World War II

World War II, or the Second World War, was a global military conflict, the amalgamation of what had initially been two separate conflicts. The first began in Asia in 1937 as the Second Sino-Japanese War; the other began in Europe in 1939 with the German invasion of Poland. This global conflict split the majority of the world's nations into two opposing military alliances: the Allies and the Axis Powers. Spanning much of the globe, World War II resulted in the death of over 60 million people, making it the deadliest conflict in human history.

World War II involved the mobilization of over 100 million military personnel, making it the most widespread war in history. The war placed the participants in a state of "total war", erasing the distinction between civil and military resources. This resulted in the complete activation of a nation's economic, industrial, and scientific capabilities for the purposes of the war effort; nearly two-thirds of those killed in the war were civilians. Nearly 11 million of these civilian casualties were victims of the Holocaust—which was conducted by Nazi Germany—largely in Eastern Europe and the Soviet Union. The financial cost of the war is estimated at about a trillion 1944 U.S. dollars worldwide, making it the most expensive war in capital as well as lives.

The Allies were victorious, and, as a result, the United States and Soviet Union emerged as the world's two leading superpowers. This set the stage for the Cold War, which lasted for the next 45 years. The United Nations was formed in hopes of preventing another such conflict. The self determination spawned by the war gave rise to decolonization movements in Asia and Africa, while Europe itself began moving toward integration.

Japan invaded Manchuria in September 1931, capturing it from the Chinese. Two years later in 1933, the Nazi Party came to power in Germany. Under Nazi leader Adolf Hitler, Germany began to rearm and to pursue a new nationalist foreign policy. By 1938, Hitler was starting to make moves to expand Germany eastwards.

In July 1937, Japan launched a large-scale invasion of mainland China, beginning with the bombing of Shanghai and Guangzhou and followed by the Nanking massacre in December.

Meanwhile, in Europe, Germany — and to a somewhat lesser extent, Italy — increasingly became more aggressive in their foreign policies.

The British government under Neville Chamberlain however, regarded the Soviet Union as a greater threat to Europe. The United Kingdom and France eventually adopted a policy of appeasement, hoping to maintain a strong, anti-communist Germany to block Soviet expansion.

Finally, in September 1939, Germany invaded Poland in cooperation with the Soviet Union, and Europe was once again at war.

Initially, the French and British did not declare war against Germany, instead they tried to persuade Hitler through diplomacy, but Hitler did not respond. The United Kingdom and France then declared war, but during the winter of 1939–1940, there was little fighting done as neither side was willing to engage the other directly. This period is often referred to as the Phoney War.

In the spring of 1940, Germany invaded Denmark and Norway, followed by France and the Low Countries in early summer. Italy also declared war against Britain and France in June 1940.

An attack on the United Kingdom was then engaged, with the Germans attempting to cut the island off from vitally needed supplies and obtain air superiority in order to enable a sea borne invasion.

This sea borne invasion never happened, but the Germans continued to attack the British mainland throughout the war. Unable to engage German forces on the European continent, the United Kingdom instead concentrated on combating German and Italian forces in the Mediterranean Basin.

They had limited success however, as they failed to prevent the Axis' conquest of the Balkans and were stalemated in the Western Desert Campaign.

The British had greater success in the theater of the Mediterranean Sea, dealing severe damage to the Italian Navy, and inflicting the first major defeat on Germany at the Battle of Britain.

The extent of the war increased in June 1941, when Germany invaded the Soviet Union, forcing them into an alliance with the United Kingdom. The German attack was initially highly successful, overrunning great tracts of Soviet territory, but by winter, it had begun to stall.

After invading mainland China and French Indochina in 1940, Japan was subjected to increasing economic sanctions by the United States, Great Britain and Netherlands. The Japanese were attempting to reduce these sanctions through diplomatic negotiations. These negotiations did not go well, and in December 1941 the war expanded once more when Japan launched nearly simultaneous attacks against the United States and British assets in Southeast Asia. Four days after Pearl Harbor, Germany also declared war on the United States. This brought the United States and Japan into the greater conflict and turned the previously separate Asian and European wars into a single global one.

Although Axis forces continued to make gains, in 1942 the tide began to turn. Japan suffered its first major defeat against American forces in the Battle of Midway, where four of Japan's aircraft carriers were destroyed. German forces in Africa were being pushed back by Anglo-American forces, and Germany’s renewed summer offensive in the Soviet Union had ground to a halt.

This was followed In 1943 by a German defeat in which they suffered devastating losses to the Soviets at Stalingrad, and then again at the Battle of Kursk, widely considered the greatest tank battle in military history. German forces were expelled from Africa, and Allied forces began driving northward up through Sicily and Italy. Italy was forced to sign the Italian Armistice in September 1943. The Japanese continued to lose ground as the American forces seized island after island in the Pacific Ocean.

In 1944, the course of the war had clearly become unfavourable for the Axis. Germany became boxed in as the Soviet offensive became a juggernaut in the east, pushing the Germans out of Russia and pressing into Poland and Romania. In the west, the Allies invaded mainland Europe, liberating France and the Low Countries and reaching Germany’s western borders. While Japan did launch a successful major offensive in China, their navy suffered continued heavy losses in the Pacific, as American forces captured airfields within bombing range of Tokyo.

The war finally ended in 1945; in Europe, the Battle of the Bulge, a final German counter-attack in the west, failed, while Soviet forces captured Berlin in May. These losses forced Germany to surrender. The Asian theater saw American forces capturing the Japanese islands of Iwo Jima and Okinawa while British forces in South East Asia managed to expel Japanese forces there. Though initially unwilling to surrender, Japan finally capitulated after the Soviet Union invaded Manchukuo and the United States dropped atomic bombs on mainland Japan.

Events leading up to the war in Europe

Germany and France had been struggling for dominance in Continental Europe for 80 years and had fought two previous wars, the Franco-Prussian War and World War I.

Following the Russian Revolution of 1917, Communist revolutionary movements began spreading across Europe, briefly taking power in both Budapest and Bavaria. As a reaction to these movements, fascist and nationalist groups were born.

In 1922, Italian dictator Benito Mussolini and his fascist party took control of the Kingdom of Italy and set the model for German dictator Adolf Hitler's Nazi Party, which, aided by the civil unrest caused by the Great Depression, took power in Germany and eliminated its democratic government, the Weimar Republic.

These two leaders began to re-militarise their countries and became increasingly hostile.

Mussolini first conquered the African nation of Abyssinia and then seized Albania, with both Italy and Germany actively supporting Francisco Franco's fascist Falange party in the Spanish Civil War against the Second Spanish Republic (which was supported by the Soviet Union).

Hitler then broke the Treaty of Versailles by increasing the size of the Germany’s military, and remilitarized the Rhineland.

He started his own expansion of Germany by annexing Austria and also the German-speaking regions (Sudetenland) of Czechoslovakia.

The British government under Neville Chamberlain saw the Soviet Union as a greater threat to Europe and he pursued a policy of appeasement towards Germany, hoping to maintain a strong, anti-communist Germany to block Soviet expansion.

This policy culminated in the Munich Agreement in 1938, which gave the Sudetenland to Germany. In March 1939, Germany occupied the remainder of Czechoslovakia. Mussolini also invaded and annexed Albania in April.

These events caused the United Kingdom and France to prepare for war against Germany. France and Poland pledged on May 19, 1939, to provide each other with military assistance in the event either was attacked. The following August, the British guaranteed the same.

On August 23, 1939, Germany and the Soviet Union signed the Molotov-Ribbentrop Pact which provided for sales of oil and food from the Soviets to Germany, thus reducing the danger of a British blockade such as the one that had nearly starved Germany in World War I. Also included was a secret agreement that would divide Central Europe into German and Soviet areas of interest, including a provision to partition Poland. Each country agreed to allow the other a free hand in its area of influence, including military occupation.  

Germany’s war against the Western Allies

Blitzkrieg

On September 1, 1939, Germany invaded Poland, using the false pretext of a staged "Polish attack" on a German border post. On September 3, the United Kingdom issued an ultimatum to Germany. No reply was received, and Britain, Australia and New Zealand declared war on Germany, followed later that day by France. Soon afterwards, South Africa, Canada and Nepal also declared war on Germany. Immediately, the UK began seizing German ships and implementing a blockade.

Despite the French and British treaty obligations and promises to the Polish government, both France and the UK were unwilling to launch a full invasion of Germany. The French mobilized slowly and then mounted only a short token offensive in the Saar; neither did the British send land forces in time to support the Poles. The geographical location of Poland meant that a full-scale British and French attack was unlikely. The French were firmly in the 'Maginot Mentality' to invade Germany, and the protection of the Maginot Line gave the French and British forces no reason to attack Germany directly. Meanwhile, on September 8, the Germans reached Warsaw, having ripped through the Polish defences. On September 17, the Soviet Union, pursuant to its prior agreement with Germany, invaded Poland from the east. Poland was soon overwhelmed, and the last Polish units surrendered on October 6.

After Poland fell, Germany paused to regroup during the winter while the British and French stayed on the defensive. The period was referred to by journalists as "the Phoney War" because of the inaction on both sides. In Eastern Europe, the Soviets began occupying Baltic states leading to a confrontation with Finland, a conflict which ended with land concessions to the Soviets on March 12, 1940. In early April 1940, both German and Allied forces launched nearly simultaneous operations around Norway over access to Swedish iron ore. It was a two-month campaign that resulted in complete German control of Denmark and Norway, though at a heavy cost to their surface navy. The fall of Norway led to the Norway Debate in London, which added to the call for the resignation of Prime Minister Neville Chamberlain, who was eventually replaced by Winston Churchill. After witnessing the defeat of the Appeasement Foreign Policy, used by Britain since the 1920s, Chamberlain was in the fire to be labelled as the 'Guilty Man' when in fact he had pushed forward for most of Britain's much needed defence spending in early 1938, and can be seen as the saviour of Britain during the Battle of Britain.

On May 10, 1940, the Germans invaded France and the Low Countries. The British Expeditionary Force (BEF) and the French Army advanced into Flanders and planned to fight a mobile war in the north, while maintaining a static continuous front along the Maginot Line further south. This was foiled by an unexpected German thrust through the Ardennes, splitting the Allies in two. The BEF and French forces, encircled in the north, were evacuated from Dunkirk in Operation Dynamo. Italy attacked France in the Alps in June 10 1940. France, overwhelmed by the blitzkrieg, was forced to sign an armistice with Germany on June 22 1940, leading to the direct German occupation of Paris and two-thirds of France, and the establishment of a German puppet state headquartered in south-eastern France known as Vichy France.

With only the United Kingdom remaining as an opposing force in Europe, Germany began to prepare Operation Sealion, the invasion of Britain. Most of the British Army's heavy weapons and supplies had been lost at Dunkirk, but the Royal Navy was still stronger than the Kriegsmarine and kept control of the English Channel. The Germans then attempted to gain air superiority by destroying the Royal Air Force (RAF) using the Luftwaffe. The ensuing air war in the late summer of 1940 became known as the Battle of Britain. The Luftwaffe initially targeted RAF Fighter Command aerodromes and radar stations, but Luftwaffe Commander Hermann Göring and Hitler switched their attention towards bombing British cities, an offensive which became known as The Blitz. This diversion of resources allowed the RAF to rebuild their airbases, eventually leading Hitler to give up on his goal of establishing air superiority over the English Channel; this in turn led to the permanent postponement of Operation Sealion.

With Germany and her allies having total control of the continent, the United Kingdom and its allies settled for strategic bombing and special forces operations in mainland Europe. Many of the conquered nations formed governments in exile and military units within the United Kingdom as well as domestic resistance movements. Germany, meanwhile, fortified its position by constructing the Atlantic Wall.

Battle of the Atlantic

Main article: Battle of the Atlantic (1939–1945)

File:Aerial view of a convoy.jpg

The Battle of the Atlantic, a nautical campaign which lasted the duration of the war, started after the German invasion of Poland with the torpedoing of the British liner SS Athenia by a German submarine (U-boat). Having faced raids on shipping during the First World War, the British quickly implemented a convoy solution to protect merchant vessels; they were short of escort ships though, so many merchant ships had to sail without protection. At first, U-boats primarily operated within British waters while German surface vessels covered the Atlantic Ocean. The British attempted to counter the U-boat threat by forming anti-submarine hunting groups, which were ultimately ineffective because the U-boats proved too elusive.

With the German conquest of Norway and France by June 1940, U-boats enjoyed decreased resistance. The French Navy was removed as an Allied force, and additional ports in France on the Atlantic Ocean became available to the German Navy (Kriegsmarine), allowing them to increase the range of their vessels. The Royal Navy became severely stretched, having to remain stationed in the English Channel to protect against a German invasion, send forces to the Mediterranean Sea to make up for the loss of the French fleet, and provide escort for merchant vessels. This was somewhat mitigated by the Destroyers for Bases Agreement with the United States Navy in September 1940, in which the British exchanged several of their overseas bases for fifty destroyers which were then used for escort duties. The success of U-boats in this period led to an increase of their production and the development of the wolf pack technique.

The German surface navy, which had suffered substantial losses in the capture of Norway, had mixed results. While there were several successful merchant raids, such as Operation Berlin, they also suffered several losses, such as the heavy cruiser Graf Spee and battleship Bismarck. The loss of the Bismarck had deeper ramifications on naval policy though, because as a result Hitler ordered all heavy surface vessels to Norwegian waters [1], shifting them from raiding operations to protection from a potential Allied invasion of Scandinavia. While the Royal Navy also suffered the loss of capital ships, such as the aircraft carrier HMS Courageous, the battleship HMS Royal Oak and the battlecruiser HMS Hood, their larger surface navy was better able to absorb the losses.

In May 1941, the British captured an intact Enigma machine, which greatly assisted in breaking German codes and allowed for plotting convoy routes, which evaded U-boat positions. In the summer of 1941, the Soviet Union entered the war on the side of the Allies, but they lost much of their equipment and manufacturing base in the first few weeks following the German invasion. The Western Allies attempted to remedy this by sending Arctic convoys, which faced constant harassment from German forces. In September, many of the U-boats operating in the Atlantic were ordered to the Mediterranean to block British supply routes. When the United States entered the war that December, they did not take precautionary anti-submarine measures; this resulted in shipping losses so great that the Germans referred to it as a second happy time.

In February 1942, several German capital ships that were stationed in the port of Brest, France, managed to comply with Hitler's earlier order and slipped through the English Channel to their home bases in German waters, dealing a significant blow to the Royal Navy's reputation. In June, the Leigh light allowed Allied aircraft to illuminate U-boats that had been detected by the aeroplanes radar, but this was soon negated by the Germans with Metox, a radar detection system that gave them advance notice of such an aircraft's approach. In American waters, the institution of shore blackouts and an interlocking convoy system resulted in a drop in attacks, and the U-boats shifted their operations back to the mid-Atlantic by August. In December, a strong German surface navy force engaged an Arctic convoy destined for the Soviet Union and failed to destroy a single merchant ship; this resulted in the resignation of Grand Admiral (Großadmiral) Erich Raeder, supreme commander of the Kriegsmarine. He was replaced by Commander of Submarines Karl Dönitz, and all naval building priorities turned to the U-boats.

In January 1943, the British developed the H2S radar system, which was undetectable by Metox. As before, this was followed by a counter-invention on the German side, the Naxos radar detector, which allowed German fighters to home in on Allied aircraft utilizing the H2S. In the spring, the Battle of the Atlantic began to turn in favour of the Allies with the pivotal point being Black May, a period where the Allies had fewer ships sunk and the Kriegsmarine lost 25% of their active U-boats. That December, the German surface fleet lost their last active battlecruiser in the Battle of North Cape. By this time, the Kriegsmarine was unable to regain the initiative; Allied production, such as the mass-produced Liberty ships, improved antisubmarine warfare tactics, sea route patrols with long range attack aircraft, and ever-improving technology led to increasing U-boat losses and more supplies getting through. This allowed for the massive supply build up in the United Kingdom needed for the eventual invasion of Western Europe in mid-1944.

Mediterranean, Africa, and the Middle East

Main articles: Mediterranean Theatre of World War II, Middle East Theatre of World War II, and African campaigns of World War II

Control of Southern Europe, the Mediterranean Sea and North Africa was important because the British Empire depended on shipping through the Suez Canal. If the canal fell into Axis hands or if the Royal Navy lost control of the Mediterranean, then transport between the United Kingdom, India, and Australia would have to go around the Cape of Good Hope, an increase of several thousand miles.

Almost immediately after declaring war on France and the United Kingdom in June 1940, Italy initiated the siege of Malta, an island under British control located in the Mediterranean between mainland Italy and its colony in Libya. Both sides initially placed minimal resources though, the Italians needing to reserve their strength for other planned invasions and the British not believing they could effectively defend it. As the importance of the campaigns in North Africa increased though, so did that of Malta and the disruptions of Axis supply lines that Allied forces stationed there could provide.

Following the French surrender, the British attacked the French Navy anchored in North Africa in July 1940, out of fear that it might fall into German hands; this contributed to a souring of British-French relations for the next few years. Soon following this action was the Battle of Calabria, the first large conflict between the Allied navies and the Italian Navy (Regia Marina).

With France no longer a threat, the Kingdom of Italy was able to relax its guard on its western possessions in Africa which bordered French territory and focus on the British Commonwealth forces in the east. In June 1940 the Italians made small incursions into British-protected Egypt, starting the North African campaign, and into Sudan and Kenya. In August, Italy invaded British Somaliland, located in the Horn of Africa, expelling British Commonwealth forces and enlarging the Italian Empire in Italian East Africa.

The Allies, including Free French Forces, under Charles de Gaulle, then attempted to replace Vichy control over French territories with that of the Free French. In September 1940, they made a failed attempt to capture French West Africa, though in November, they later succeeded in French Equatorial Africa. Between these attempts, the Italians launched their own offensive from Albania and attacked Greece.

Starting in November 1940, the Allies had a string of successful operations against Italian forces. On November 12 they launched the first all-aircraft naval attack against the Italian fleet at Taranto. Then, in December, British Commonwealth forces under General Archibald Wavell, launched Operation Compass, expelling Italian forces from Egypt and pushing them all the way west across Libya. Starting in January 1941, British Commonwealth forces began an offensive into Italian East Africa, culminating in an Italian defeat. Italy was also facing problems in the Balkans, where the Greek Army had pushed the Italians out of Greece and were now stalemated in southern Albania.

Alarmed by the Italian setbacks, Hitler authorized reinforcements, and sent German forces to Africa in February. British Commonwealth leader started redeploying their forces, sending soldiers from North Africa to Greece starting in early March; in an effort to secure their transportation lines, the Allied navies managed to engage the Regia Marina in the Battle of Cape Matapan, doing significant damage to the Italian fleet. The German forces in Africa, led by German General Erwin Rommel, however, launched an offensive against the now depleted British Commonwealth forces near the end of March. During this offense, the Allies also feared having their oil supply cut due to a coup d'état in Iraq in early April. They were further pressed when the Germans invaded Greece and Yugoslavia. By the middle of April, Rommel's forces had pushed British Commonwealth forces back into Egypt with the exception of the port of Tobruk, which he encircled and besieged. Shortly after, the British responded to the coup in Iraq by invading and occupying the country. By the end of April, German forces (with Italian and other Axis Armies) had conquered Yugoslavia, mainland Greece and further captured the island of Crete, forcing a withdrawal of all British Commonwealth forces from the Balkans.

In June 8, British Commonwealth and Free French forces invaded Vichy controlled Syria and Lebanon due to the Vichy allowance of Axis forces to pass through the area and utilize military bases. A week later, Wavell launched Operation Battleaxe, which was intended to be a major offensive in the Western Desert, but resulted in the loss of nearly half of the British Commonwealth tanks in the region. Frustrated by the lack of success, Churchill had Wavell replaced with Claude Auchinleck in early July. In late August, after the German invasion of the Soviet Union, the British and the Soviets launched a joint invasion of Iran to secure its oilfields and the Persian Corridor supply route for Soviet use.

There was then a lull in activity. The Soviet-German war had significantly reduced the importance of the Mediterranean theatre to the Germans and the British Commonwealth armies were re-grouping. On November 18, the Allies launched Operation Crusader, an offensive in the Western Desert, which pushed Rommel back to his original starting point at El Agheila in Libya. The British suffered a significant blow in the Mediterranean sea though, losing several ships shortly after the First Battle of Sirte.

With the entry of Japan into the war in December 1941, the British Commonwealth forces were again forced to withdraw units in North Africa, transferring some to Burma. In a show of support to their ally, Germany and Italy both declared war on the United States on 11-December-1941.

Once again, Rommel took advantage of the situation, and on January 21, launched an offensive, which pushed the British Commonwealth forces back to Gazala, just west of Tobruk. There was another lull in activity as both sides built up their forces. In May, after the Japanese Indian Ocean raid, British Commonwealth forces invaded Vichy controlled Madagascar to prevent the Imperial Japanese Navy from using as launch point for further such attacks. Rommel (with his Afrika Korps and the Italian Army) launched his own attack in late May, overrunning successively the British position in the Western Desert (Battle of Tobruk) and chasing them well into Egypt, being halted at El Alamein. Shortly after, the Royal Navy suffered significant damage getting much needed supplies to Malta from the Italian Regia Marina.

Like Wavell before him, Auchinleck's perceived failures led to his replacement by Churchill, this time by Harold Alexander with Bernard Montgomery taking over Allied land forces in Egypt.

In late October, after building up his forces, Montgomery launched his offensive, pushing the Axis forces back and pursuing them across the desert. In November, Allied forces landed in Vichy-controlled Northwest Africa with minimal resistance; in retaliation, the Germans seized the remainder of mainland France, though they failed to capture the remainder of the French Navy. Soon, Rommel's forces were pincered in Tunisia and by May 1943, were forced to evacuate Africa entirely.

In July, the Italian Campaign began with the Allied invasion of Sicily. The continued series of Italian defeats led to Mussolini being dismissed by the King of Italy, Victor Emmanuel III and subsequently arrested. His successor, Pietro Badoglio, then began negotiating surrender with the Allies. On September 3 the Allies invaded Italy itself and the Italians signed an armistice. This was made public on September 8; the same day the Allies launched a subsequent invasion of the Italian held Dodecanese islands. Germany had been planning for such an event though, and executed Operation Achse, the seizure of northern and central Italy. A few days later, Mussolini was rescued by German special forces and before the end of September created the Italian Social Republic, a German client state.

From October until mid-1944, the Allies fought through a series of defensive lines and fortifications designed to slow down their progress. One of strongest of the German defensive lines, the Winter Line, was breached nearly simultaneously in May at Monte Cassino by British-led forces and at Anzio by the Americans; though the Allies could have encircled and potentially destroyed the bulk of German forces in Italy, the American forces instead moved towards Rome, capturing the city on June 4.

In August, Allied forces in Italy were divided, with a significant portion sent to southern France to assist in the liberation of Western Europe while the remainder pressed north to engage the remaining German forces, notably at the Gothic Line. On April 25, 1945, a little over a year and half after its creation, the Italian Social Republic was overthrown by Italian partisans; Mussolini, his mistress and several of his ministers were captured by the partisans while attempting to flee and executed. Fighting in Italy would continue until early May 1945, only a few days before the general German surrender.

You are about to embark upon the Great Crusade, toward which we have striven these many months. The eyes of the world are upon you. The hopes and prayers of liberty-loving people everywhere march with you. In company with our brave Allies and brothers-in-arms on other Fronts, you will bring about the destruction of the German war machine, the elimination of Nazi tyranny over the oppressed peoples of Europe, and security for ourselves in a free world. – Dwight D. Eisenhower

In the East, the vastness of space will … permit a loss of territory … without suffering a mortal blow to Germany’s chance for survival. Not so in the West! If the enemy here succeeds … consequences of staggering proportions will follow within a short time. – Adolf Hitler

Supplies coming ashore during the Battle of Normandy.

By the spring of 1944, the Allied preparations for the invasion of France and the initial stages for the liberation of Western Europe (Operation Overlord) were complete. They had assembled around one hundred twenty Divisions, consisting of over two million men, of whom 1.3 million were Americans, 600,000 were British and the rest Canadian, Free French and Polish. The invasion, code-named Operation Neptune but commonly referred to as D-Day, was set for June 5 but bad weather postponed the invasion to June 6, 1944. Almost 85–90% of all German troops were deployed on the Eastern Front and only 400,000 Germans in two armies, the German Seventh Army and the newly created Fifth Panzer Army, were stationed in the area. The Germans had also constructed an elaborate series of fortifications along the coast called the Atlantic Wall, but in many places the Wall was incomplete. The Allied forces under supreme command of Dwight D. Eisenhower had launched an elaborate deception campaign to convince the Germans that the landings would occur in the Calais area, which caused the Germans to deploy many of their forces in that sector. Only 50,000 Germans were deployed in the Normandy sector on the day of the invasion.

The invasion began with 17,000 airborne troops being dropped in Normandy to serve as a screening force to prevent the Germans from attacking the beaches. During the early morning, a massive naval flotilla bombarded German defenses on the beaches, but due to lack of visibility, most of the shots missed their targets. Additionally, most of the troop transport ships (with personnel, trucks, and equipment) were off-course, some as much as thousands of yards from their respective landing zone amongst the five beach areas (Utah, Omaha, Sword, Juno and Gold). The Americans in particular suffered heavy losses on Omaha beach due to the German fortifications being left intact. However, by the end of the first day, most of the Allied objectives were accomplished even though the British and Canadian objective of capturing Caen proved too optimistic. The Germans launched no significant counter-attack on the beaches, as Hitler believed the landings to be a decoy. Only three days later, the German High command realized that Normandy was the actual invasion, but by then the Allies had already consolidated their beachheads.

The bocage terrain of Normandy where the Americans had landed made it ideal ground for defensive warfare. Nevertheless, the Americans made steady progress and captured the deep-water port of Cherbourg on June 26, one of the primary objectives of the invasion. However, the Germans had mined the harbor and destroyed most of the port facilities before surrendering, and it would be another month before the port could be brought back into limited use. The British launched another attack on June 13 to capture Caen but were held back as the Germans had moved in large number of troops to hold the city. The city was to remain in German hands for another 6 weeks. It finally fell to British and Canadian forces on July 9.

Allied firepower, improved tactics, and numerical superiority eventually resulted in a breakout of American mechanized forces at the western end of the Normandy pocket in Operation Cobra on July 23. The allied advance to this point had been considerably slower than expected. Seven weeks after D-Day, U.S. First Army was holding an east–west line that ran from Caumont to Saint-Lô to Lessay on the Channel. Pre-D-Day projections had put the Americans on that line by D Plus Five. When Hitler learned of the American breakout, he ordered his forces in Normandy to launch an immediate counter-offensive. However the German forces moving in open countryside were now easily targeted by Allied aircraft, as they had initially escaped Allied air attacks due to their well camouflaged defensive positions.

The Americans placed strong formations on their flanks which blunted the attack and then began to encircle the 7th Army and large parts of the 5th Panzer Army in the Falaise Pocket. Some 50,000 Germans were captured, but 100,000 managed to escape the pocket. Worse still, the British and Canadians — whose initial strategic objective to draw in enemy reserves and protect the American flanks so as to promote a later turning movement north had been achieved — now began to break through the German lines. Any hope the Germans had of containing the Allied thrust into France by forming new defensive lines was now gone. The Allies raced across France, advancing as much as 600 miles (970 km) in two weeks. The German forces retreated into Northern France, Holland and Belgium.

By August 1944, Allied forces stationed in Corsica launched Operation Dragoon, invading the French Riviera on August 15 with the 6th Army Group, led by Lieutenant General Jacob Devers), and linked up with forces from Normandy. The clandestine French Resistance in Paris rose against the Germans on August 19, and the Free French 2nd Armoured Division under General Philippe Leclerc, pressing forward from Normandy, received the surrender of the German forces on behalf of General von Choltiz from Paris and liberated the city on August 25.

Around this time the Germans began launching V-1's (known as the "buzz bomb"), the world's first cruise missile, at targets in southern England and Belgium. Later they would employ the much larger V-2 rocket, a liquid-fuelled guided ballistic missile. These weapons were inaccurate and could only target large areas such as cities; they had little military effect and were intended to demoralize and/or terrorize Allied civilians.

Logistical problems plagued the Allies as they fanned out across France and the Low Countries, advancing towards the German border. With the supply lines still running back to Normandy, and critical shortages in fuel and other supplies all along the front, the Allies slowed the general advance and focused the available supplies on a narrow front strategy. Allied paratroopers and armour attempted a war-winning advance through the Netherlands and across the Rhine River with Operation Market Garden in September (the goal was to end the war by Christmas). The plan was to land paratroopers near bridges on the Rhine River, hold the position, and wait for the armour to cut through enemy lines to reinforce them and then cross into Germany. The plan was conceived and led by British General Montgomery, and included British, American, Polish, and Canadian forces. Although the plan encountered some initial success, many of the bridges were blown up, and the advancing armoured columns ran into delays. As a result, the British 1st Airborne Division, holding the last bridge, was nearly annihilated. The Germans were able to entrench all along the front and the war continued through the winter.

In order to improve the supply situation, the Canadian First Army was assigned to clear the entrance to the port of Antwerp, the Scheldt estuary, which they successfully accomplished by late November 1944 making Canada the only country to successfully complete all D-Day objectives. In October, the Americans captured Aachen, the first major German city to be occupied.

Hitler had been planning to launch a major counter-offensive against the Allies since mid-September. The objective of the attack was to capture Antwerp. Not only would the capture or destruction of Antwerp prevent supplies from reaching the allied armies, it would also split allied forces in two, demoralizing the alliance and forcing its leaders to negotiate. For the attack, Hitler concentrated the best of his remaining forces in the west, launching the attack through the Ardennes in southern Belgium, a hilly and in places a heavily wooded region, and the site of his victory in 1940. Dense cloud cover denied the Americans the use of their reconnaissance and ground attack aircraft.

Parts of the attack managed to break through the thinly held American lines (about 4 divisions which were either new or refitting to cover about 70 miles (110 km) of the front-line), and dash headlong for the Meuse. However, the northern section of the line held, constricting the advance to a narrow corridor. The German advance was delayed at St. Vith, which American forces defended for several days. At the vital road junction of Bastogne, the American 101st Airborne Division held out, surrounded, for the duration of the battle. Patton's 3rd Army to the South made a rapid 90 degree turn and rammed into the German southern flank, relieving Bastogne.

The weather by this time had cleared unleashing allied air power as the German attack ground to a halt at Dinant. In an attempt to keep the offensive going, the Germans launched a massive air raid on Allied airfields in the Low Countries on January 1, 1945. The Germans destroyed 465 aircraft but lost 277 of their own planes. Whereas the Allies were able to make up their losses in days, the Luftwaffe was not capable of launching a major air attack again.

Allied forces from the north and south met up at Houffalize and by the end of January they had pushed the Germans back to their starting positions. Many German units were caught in the pocket created by the Bulge and forced to surrender or retreat without their heavy equipment. Months of the Reich's war production were lost whereas German forces on the Eastern front were virtually starved of resources at the very moment the Red Army was preparing for its massive offensive against Germany. The final obstacle to the Allies was the river Rhine, which was crossed in late March 1945, aided by the fortuitous capture of the Ludendorff Bridge at Remagen. Also, Operation Varsity, a parachute-assault in late March, got a foothold on the east bank of the Rhine River. Once the Allies had crossed the Rhine, the British fanned out northeast towards Hamburg, crossing the river Elbe and moving on towards Denmark and the Baltic Sea.

The U.S. 9th Army went south as the northern pincer of the Ruhr encirclement, and the U.S. 1st Army went north as the southern pincer of the Ruhr encirclement. These armies were commanded by General Omar Bradley who had over 1.3 million men under his command (the 12th Army Group). On April 4, the encirclement was completed, and the German Army Group B, which included the 5th Panzer Army, 7th Army and the 15th Army and was commanded by Field Marshal Walther Model, was trapped in the Ruhr Pocket. Some 300,000 German soldiers then became prisoners of war. The 1st and 9th U.S. Armies then turned east, halting their advance at the Elbe river where they met up with Soviet troops in mid-April.

German-Soviet War

Main article: Eastern Front (World War II)

The Eastern Front of the European Theatre of World War II encompassed the conflict in central and Eastern Europe from June 22, 1941 to May 8, 1945. It was the largest theatre of war in history in terms of numbers of soldiers, equipment and casualties and was notorious for its unprecedented ferocity, destruction, and immense loss of life. It was here that the bulk of the European war was fought; where the Red Army halted the Germans in 1941 and then inflicted the first major defeats at Stalingrad and Kursk in 1943. The fighting involved millions of German and Soviet troops along a broad front hundreds of kilometres long. It was by far the deadliest single theatre of World War II, with over 5 million Axis deaths; Soviet military deaths were about 10.6 million (out of which 2.8 – 3.5 million Soviet prisoners of war (of 5.5 million) died in German captivity), and civilian deaths were about 14 to 19 million. More people fought and died on the Eastern Front than in all other theatres of World War II combined; the German army suffered 80% to 93% of all its casualties there. Although the Soviet Union was victorious in the war, the cost to the nation was an estimated 27 million dead, about half of all World War II casualties and the vast majority of Allied deaths, and had devastated the Soviet economy in the struggle. In Soviet and Russian sources, the conflict is referred to as the Great Patriotic War.

Invasion of the Soviet Union

We have only to kick in the door and the whole rotten structure will come crashing down. – Adolf Hitler

For the campaign against the Soviet Union, the Germans allotted three army groups, totalling about 3.3 million men, along with 1 million from other Axis countries. Among these were 19 panzer divisions, and in total the “Barbarossa” force had about 3,000 tanks, 7,000 artillery pieces, and 2,500 aircraft. It was in effect the largest and most powerful invasion force in human history. Their Soviet opponents had just recently seen a drastic purge in 1933 that had crippled the Red Army, reducing its morale and efficiency just before the German invasion. With up to 50% of army officers executed, the result was that the Red Army officer corps in 1941 had many inexperienced senior officers.

The battle of Greece and the invasion of Yugoslavia delayed the German invasion of the Soviet Union by a critical six weeks, but on June 22, 1941, Germany launched its invasion of the Soviet Union.

Germany’s Army Group North was deployed in East Prussia. Its main objectives were to secure the Baltic states and seize Leningrad. Opposite Army Group North were two Soviet armies. The Germans threw their 600 tanks at the junction of the two Soviet Armies in that sector. The 4th Panzer Army's objective was to cross the Neman River and the Dvina River which were the two largest obstacles in route to Leningrad. On the first day, the tanks crossed the Neman and penetrated 50 miles (80 km). Near Rasienai, the panzers were counterattacked by 300 Soviet tanks; it took 4 days for the Germans to encircle and destroy the Soviets. The panzers then crossed the Dvina near Dvinsk, and approached Leningrad.

Army Group Centre was deployed in Poland. Its main objective was to capture Moscow. Opposite Army Group Center were four Soviet armies occupying a salient that jutted into German territory with its center at Bialystok. Beyond Bialystok was Minsk which was a key railway junction and guardian of the main highway to Moscow. 3rd Panzer Army punched through the junction of the two Soviet armies from the North and crossed the Neman River, and the 2nd Panzer Army crossed the Bug River from the south. While the panzers attacked, the infantry armies struck at the salient and encircled Soviet troops at Bialystok. The panzer armies' objective was to meet at Minsk and prevent any Soviet withdrawal. On June 27, 2nd and 3rd Panzer Armies met up at Minsk advancing 200 miles (320 km) into Soviet territory. In the vast pocket between Minsk and the Polish border, 32 Soviet infantry and eight tank divisions were encircled and were destroyed. Soviet soldiers numbering 135,000 were killed or wounded, 290,000 were captured, while another 250,000 managed to escape.

Army Group South was deployed in southern Poland and Romania and also included two Romanian armies and several Italian, Slovakian and Hungarian divisions. Its objective was to secure the oil fields of the Caucasus. Opposite the Germans in the south were three Soviet armies. The majority of the Axis forces struck at the junctions of the Soviet armies but 1st Panzer Army struck right through the Soviet Army with the objective of capturing Brody. On June 26, Soviet commanders reacted to the German attack and mounted a massive counter-attack on 1st Panzer Army with five mechanized corps with over 1,000 tanks. The battle was among the fiercest of the invasion, lasting over 4 days. In the end the Germans prevailed but the Soviets inflicted heavy losses on the 1st Panzer Army. With the failure of the Soviet armoured offensive, the last substantial Soviet tank forces in the south were now spent.

On July 3, Hitler finally gave permission to proceed for the panzers to resume their drive east after the infantry armies had caught up. The next objective of Army Group Center was the city of Smolensk, which commanded the road to Moscow. Facing the Germans was an old Russian defensive line where the Soviets had deployed six armies. On July 6, the Soviets launched an attack with 700 tanks against the 3rd Panzer Army. The Germans, using their overwhelming air superiority, wiped out the Soviet tanks. The 2nd Panzer Army crossed the Dnieper River and closed on Smolensk from the south while 3rd Panzer Army, after defeating the Soviet counter-attack, approached Smolensk from the north. Trapped between their pincers were three Soviet armies. On July 26, the panzers closed the gap and then began to eliminate the pocket, which yielded over 300,000 Soviet prisoners, although 200,000 evaded capture. Hitler by now had lost faith in battles of encirclement and wanted to defeat the Soviets by inflicting severe economic damage which meant seizing the oil fields in the south and Leningrad in the north. Tanks from Army Group Centre were diverted to Army Group North and South to aid them. Hitler's generals vehemently opposed this as Moscow was only 200 miles (320 km) away from Army Group Centre and the bulk of the Red Army was deployed in that sector and only an attack there could hope to end the war quickly. However, Hitler was adamant and the tanks from Army Group Centre arrived and reinforced the 4th Panzer Army in the north which subsequently broke through the Soviet defenses on August 8 and by the end of August was only 30 miles (48 km) from Leningrad. Meanwhile the Finns had pushed southeast on both sides of Lake Ladoga reaching the old Finnish-Soviet frontier.

In the South by mid-July below the Pinsk Marshes, the Germans had gotten to within a few miles of Kiev. The 1st Panzer Army then went South while the German 17th Army, which was on 1st Panzer Army's southern flank, struck east and between them trapped 3 Soviet armies near Uman. As the Germans eliminated the pocket, their tanks turned north and crossed the Dnieper. Meanwhile, 2nd Panzer Army, which was diverted from Army Group Centre, had crossed the Desna River with 2nd Army on its right flank. This move resulted in the trapping of four Soviet armies and parts of two others. The encirclement of Soviet forces in Kiev was achieved on September 16. The encircled Soviets did not give up easily, a savage battle ensued, lasting for 10 days, after which the Germans claimed over 600,000 Soviet soldiers captured. Hitler called it the greatest battle in history. After Kiev, the Red Army no longer outnumbered the Germans and there were no more reserves. To defend Moscow, Stalin had only 800,000 men left.

The Red Army was outflanked and on September 8, 1941, the Germans had fully encircled Leningrad and Hitler ordered the city to be besieged. The siege lasted for a total of 900 days, from September 8, 1941 until January 27, 1944. The city's almost 3 million civilians (including about 400,000 children) refused to surrender and endured rapidly increasing hardships in the encircled city. Food and fuel stocks were limited to a mere 1–2 month supply, public transport was not operational and by the winter of 1941–42 there was no heating, no water supply, almost no electricity and very little food. In January 1942 in the depths of an unusually cold winter, the city's food rations reached an all time low of only 125 grams (about 1/4 of a pound) of bread per person per day. In just two months, January and February 1942, 200,000 people died in Leningrad of cold and starvation. Despite these tragic losses and the inhuman conditions the city's war industries still continued to work and the city did not surrender.

The Soviets had mounted an increasing number of attacks against Army Group Centre, but lacking tanks, it was in no position to go on the offensive. Hitler had changed his mind and decided that tanks be sent back to Army Group Center for its all out drive on Moscow. Operation Typhoon, the drive on Moscow began on October 2. In front of Army Group Center was a series of elaborate defence lines. The Germans easily penetrated the first line as 2nd Panzer Army, returning from the south, took Orel which was 75 miles (121 km) behind the Soviet first defence line. The Germans then pushed in and the vast pocket yielded 663,000 Soviet prisoners. Soviet forces now had only 90,000 men and 150 tanks left for the defense for Moscow.

Almost from the beginning of Operation Typhoon the weather had deteriorated steadily, slowing the German advance on Moscow to as little as 2 miles (3 km) a day. On October 31, the German High Command ordered a halt on Operation Typhoon, as the armies were re-organized. The pause gave the Soviets time to build up new armies and bring in the Soviet troops from the east as the neutrality pact signed by the Soviets and Japanese in April, 1941 assured Stalin that there was no longer a threat from the Japanese.

On November 15, the Germans resumed the attack on Moscow. Facing the Germans were six Soviet armies. The Germans intended to let the 3rd and 4th Panzer Armies cross the Moscow Canal and envelop Moscow from the North East. The 2nd Panzer Army would attack Tula and then close in on Moscow from the south and the 4th Army would smash in the center. However, on November 22, Soviet Siberian troops were unleashed on the 2nd Panzer Army in the South, which inflicted a shocking defeat on the Germans. The 4th Panzer Army succeeded in crossing the Moscow canal and on December 2 had penetrated to within 15 miles (24 km) of the Kremlin. However, by then, the first blizzards of the winter began and the Wehrmacht was not equipped for winter warfare. Frostbite and disease had caused more casualties than combat; dead and wounded had already reached 155,000 in 3 weeks. Some divisions were now at 50% strength and the bitter cold had caused severe problems for weapons and equipment. Weather conditions grounded the Luftwaffe. Hitler's plans miscarried at the onset of severe winter weather; he was so confident of a lightning victory that he did not prepare for even the possibility of winter warfare. Yet, his eastern army suffered more than 734,000 casualties (about 23% of its average strength of 3,200,000 troops) during the first five months of the invasion, and on 27 November 1941, General Eduard Wagner, the Quartermaster General of the German Army, reported, "We are at the end of our resources in both personnel and materiel. We are about to be confronted with the dangers of deep winter." Newly built up Soviet troops near Moscow now numbered over 500,000 men and Zhukov on December 5 launched a massive counter attack which pushed the Germans back over 200 miles (320 km) but no decisive breakthrough was achieved. The invasion of the Soviet Union had so far cost the Germans over 250,000 dead, 500,000 wounded and most of their tanks.

Germany’s second offensive

On January 6, 1942, Stalin, confident after his earlier victory, ordered a general counter-offensive. Initially the attacks made good ground as Soviet pincers closed around Demyansk and Vyazma and threatening attacks were made towards Smolensk and Bryansk. Despite these successes, the Soviet offensive soon ran out of steam. By March, the Germans had recovered and stabilized their line and secured the neck of the Vyazma Pocket. Only at Demyansk was there any serious prospect of a major Soviet victory. Here a large part of the German 16th Army had been surrounded. Hitler ordered no withdrawal and the 92,000 men trapped in the pocket were to hold their ground while they were re-supplied by air. For ten weeks, they held out until April when a land corridor was opened to the west. The German forces retained Demyansk until they were permitted to withdraw in February 1943.

In May, the Soviets attempted to retake the city of Kharkov, in Eastern Ukraine. They opened with concentric attacks on either side of Kharkov and in both sides broke through German lines and a serious threat to the city emerged. In response, the Germans accelerated the plans for their own offensive and launched it 5 days later. The German 6th Army struck at the salient from the south and encircled the entire Soviet army assaulting Kharkov. In the last days of May, the Germans destroyed the forces inside the pocket. Of the Soviet troops inside the pocket, 70,000 were killed, 200,000 captured and only 22,000 managed to escape.

Hitler had by now realized that his Armies were too weak to carry out an offensive on all sectors of the Eastern Front, but if the Germans could seize the oil and fertile rich area of the Southern Soviet Union this would give the Germans the means to continue with the war. Operation Blue attempted the destruction of the Red Army's southern front, consolidation of the Ukraine west of the River Volga, and the capture of the Caucasus oil fields. The Germans reinforced Army Group South by transferring divisions from other sectors and getting divisions from Axis allies. By late June, Hitler had 74 Divisions ready to go on the offensive, 51 of them German.

The Soviets did not know where the main German offensive of 1942 would come. Stalin was convinced that the German objective of 1942 would be Moscow and over 50% of all Red Army, troops were deployed in the Moscow region. Only 10% of Soviet troops were deployed in the Southern Soviet Union.

On June 28, 1942, the German offensive began. Everywhere Soviet forces fell back as the Germans sliced through Soviet defenses. By July 5, forward elements of 4th Panzer Army reached the River Don near Voronezh and got embroiled in a bitter battle to capture the city. The Soviets, by tying down 4th Panzer Army, gained vital time to reinforce their defenses. The Soviets for the first time in the war were not fighting to hold hopelessly exposed positions but were retreating in good order. As German pincers closed in, they only found stragglers and rear guards. Angered by the delays, Hitler re-organized Army Group South to two smaller Army Groups, Army Group A and Army Group B. The bulk of the Armored forces were concentrated with Army Group A which was ordered to attack towards the Caucasus oil fields while Army Group B was ordered to capture Stalingrad and guard against any Soviet counter attacks.

By July 23, the German 6th Army had taken Rostov but Soviet troops fought a skillful rearguard action, which embroiled the Germans in heavy urban fighting to take the city. This also allowed the main Soviet formations to escape encirclements. With the River Don's crossing secured in the south and with the 6th Army's advance flagging, Hitler sent the 4th Panzer Army back to join up with 6th Army. In late July, 6th Army resumed its offensive and by August 10, 6th Army cleared the Soviet presence from the west bank of the River Don but Soviet troops held out in some areas, further delaying 6th Army's march east. In contrast, Army Group A after crossing the River Don on July 25 had fanned out on a broad front. The German 17th Army swung west towards the Black Sea, while the 1st Panzer Army attacked towards the south and east sweeping through country largely abandoned by Soviet troops. On August 9, 1st Panzer Army reached the foothills of the Caucasus Mountains, an advance of more than 300 miles (480 km).

Soviet soldiers fighting during the Battle of Stalingrad, 1942 – a turning point in the war

In order to protect their forces in the Caucasus, the Germans attempted to capture Stalingrad, on their northeastern flank, crossing the Don River and advancing on the city. Germans bombers killed over 40,000 people and turned much of the city into rubble. The Soviet leadership realized that the German plan was the seizure of the oil fields and began sending large number of troops from the Moscow sector to reinforce their troops in the South. Zhukov, one of Stalin's most trusted generals, assumed command of the Stalingrad front in early September and mounted a series of attacks from the North which further delayed the German 6th Army's attempt to seize Stalingrad. On September 13, the Germans advanced through the southern suburbs and by September 23, 1942, the main factory complex was surrounded and the German artillery was within range of the quays on the river, across which the Soviets evacuated wounded and brought in reinforcements. Ferocious street fighting, hand-to-hand conflict of the most savage kind now ensued in the ruins of the city. Besides being a turning point in the war, Stalingrad was also revealing in terms of the discipline and determination of both the German Wehrmacht and the Soviet Red Army.

Captured German soldiers during the Battle of Stalingrad, 1943.

The Soviets first defended Stalingrad against a fierce German onslaught. So great were Soviet losses that at times, the life expectancy of a newly arrived soldier was less than a day, and life expectancy of Soviet officer was three days. Their sacrifice is immortalized by a soldier of General Rodimtsev, about to die, who scratched on the wall of the main railway station (which changed hands 15 times during the battle) “Rodimtsev’s Guardsmen fought and died here for their Motherland.” Exhaustion and deprivation gradually sapped men's strength. Hitler, who had become obsessed with the battle of Stalingrad, refused to countenance a withdrawal. General Paulus, in desperation, launched yet another attack early in November by which time the Germans had managed to capture 90% of the city. The Soviets, however, had been building up massive forces on the flanks of Stalingrad, which were by this time undermanned as the bulk of the German forces had been concentrated in capturing the city, and Axis satellite troops were left guarding the flanks. The Soviets launched Operation Uranus on November 19, 1942, with twin attacks that met at the city of Kalach four days later, encircling the 6th Army in Stalingrad.

The Germans requested permission to attempt a breakout, which was refused by Hitler, who ordered Sixth Army to remain in Stalingrad where he promised they would be supplied by air until rescued. About the same time, the Soviets launched Operation Mars in a salient near the vicinity of Moscow. Its objective was to tie down Army Group Center and to prevent it from reinforcing Army Group South at Stalingrad.

Meanwhile, Army Group A's advance into the Caucasus had stalled as Soviet troops had destroyed the oil production facilities and a year's work was required to bring them back up, the other remaining oil fields lay south of the Caucasus Mountains. Throughout August and September, German Mountain troops probed for a way through but by October, with the onset of winter, they were no closer to their objective. With German troops encircled in Stalingrad, and Soviet armies threatening their lines of retreat, Army Group A began to fall back.

By December, Field Marshal von Manstein hastily put together a German relief force of units composed from Army Group A to relieve the trapped Sixth Army. Unable to get reinforcements from Army Group Center, the relief force only managed to get within 50 kilometers (30 mi) before they were turned back by the Soviets. By the end of the year, the Sixth Army was in desperate condition, as the Luftwaffe was able to deliver only about a sixth of the supplies needed.

Shortly before surrendering to the Red Army on February 2, 1943, Friedrich Paulus was promoted to Field Marshal. This was a message from Hitler, because no German Field Marshal had ever surrendered his troops or been taken alive. Of the 300,000 strong 6th Army, only 91,000 survived to be taken prisoner, including 22 generals, of which only 5,000 men ever returned to Germany after the war. This was to be the greatest, and most costly, battle in terms of human life in history. Around 2 million men were killed or wounded on both sides, including civilians, with Axis casualties estimated to be about 850,000 and 750,000 for the Soviets.

After the surrender of the German Sixth Army at Stalingrad on February 2, 1943, the Red Army launched eight offensives during the winter. Many were concentrated along the Don basin near Stalingrad. These attacks resulted in initial gains until German forces were able to take advantage of the over extended and weakened condition of the Red Army and launch a counter attack to re-capture the city of Kharkov and surrounding areas. This was to be the last major strategic German victory of World War II.

The rains of spring inhibited campaigning in the Soviet Union, but both sides used the interval to build up for the inevitable battle that would come in the summer. The start date for the offensive had been moved repeatedly as delays in preparation had forced the Germans to postpone the attack. By July 4, the Wehrmacht, after assembling their greatest concentration of firepower during the whole of World War II, launched their offensive against the Soviet Union at the Kursk salient. Their intentions were known by the Soviets, who hastened to defend the salient with an enormous system of earthwork defenses. The Germans attacked from both the north and south of the salient and hoped to meet in the middle, cutting off the salient and trapping 60 Soviet divisions. The German offensive in the Northern sector was ground down as little progress was made through the Soviet defenses but in the Southern Sector, there was a danger of a German breakthrough. The Soviets then brought up their reserves to contain the German thrust in the Southern sector, and the ensuing Battle of Kursk became the largest tank battle of the war, near the city of Prokhorovka. The Germans lacking any sizable reserves had exhausted their armored forces and could not stop the Soviet counteroffensive that threw them back across their starting positions.

The Soviets captured Kharkov following their victory at Kursk and with the autumn rains threatening, Hitler agreed to a general withdrawal to the Dnieper line in August. As September proceeded into October, the Germans found the Dnieper line impossible to hold as the Soviet bridgeheads grew. Important Dnieper towns started to fall, with Zaporozhye the first to go, followed by Dnepropetrovsk. Early in November, the Soviets broke out of their bridgeheads on either side of Kiev and recaptured the Ukrainian capital. The 1st Ukrainian Front attacked at Korosten on Christmas Eve, and the Soviet advance continued along the railway line until the 1939 Soviet-Polish border was reached.

Soviet offensive

Main articles: Operation Bagration and Lvov-Sandomierz Offensive

The Soviets continued to advance in a series of offensives that began in January 1944 and lasted right through spring. By the time the Soviet offensives ran out of steam in mid-April, they had nearly reached the Carpathian Mountains and Poland in the south and had pushed the Germans one hundred miles back away from Leningrad in the north. German units had to occupy Hungary to keep its government from pulling out of the War. Germany’s co-belligerent, Finland, had sought a separate peace with Stalin in February 1944, but would not accept the initial terms offered. On June 9, the Soviet Union began the Fourth strategic offensive on the Karelian Isthmus that, after three months, forced Finland to accept an armistice.

Before the Soviets could begin their summer offensive into Belarus, they had to clear the Crimea peninsula of Axis forces. Remnants of the German Seventeenth Army of Army Group South and some Romanian forces were cut off and left behind in the peninsula when the Germans retreated from the Ukraine. In early May, the Red Army's 3rd Ukrainian Front attacked the Germans and the ensuing battle was a complete victory of the Soviet forces and a botched evacuation effort across the Black Sea by Germany failed.

With the Crimea cleared, the long awaited Soviet summer offensive codenamed, Operation Bagration, began on June 22, 1944 which involved 2.5 million men and 6,000 tanks. Its objective was to clear German troops from Belarus and crush German Army Group Center that was defending that sector. The offensive was timed to coincide with the Allied landings in Normandy but delays caused the offensive to be postponed for a few weeks. The Soviets had fooled German intelligence into thinking the attack would come against Army Group North Ukraine, but instead they launched a gigantic pincer attack against Army Group Center. Within twelve days, twenty-five German divisions — at least three hundred thousand men — disappeared from the German order of battle. The Soviets only stopped in mid-July to bring up supplies and repair the transport net before pushing on. The Soviets swept forward, reaching the outskirts of Warsaw on July 31, advancing more than two hundred miles. It was the greatest defeat for the Wehrmacht during the war.

The proximity of the Red Army led the Poles in Warsaw to believe they would soon be liberated. On August 1, they revolted as part of the wider Operation Tempest. Nearly 40,000 Polish resistance fighters seized control of the city. The Soviets, however, did not advance any further. The only assistance given to the Poles was artillery fire, as German army units moved into the city to put down the revolt. The resistance ended on October 2. German units then destroyed most of what was left of the city.

The Soviets widened their initial drive with attacks against two other army groups, North and North Ukraine, starting in mid-July. By the end of the first week of August, they had nearly cut off Army Group North from the rest of the front, and from there south had reached the border of East Prussia, the Vistula River below Warsaw, and the Hungarian border along the Carpathian Mountains. Later in August the Soviets advanced into Romania. The Romanians opted not to fight and the Germans lost over 380,000 men in about two weeks of fighting withdrawal. Over the course of the next three months, the Soviets occupied Bulgaria — which declared war on Germany as soon as the Russians arrived — and advanced northwestward from Romania across Transylvania into Hungary.

Following the German retreat from Romania, the Soviets entered Hungary in October 1944 but the Germans managed to encircle and defeat the initial Soviet drive near Debrecen, Hungary. The rapid assault the Soviets had hoped that would lead to the capture of Budapest was now halted and Hungary would remain Germany’s ally until the end of the war in Europe. This battle would be the last German victory in the Eastern Front. In Yugoslavia, the tide of the civil war was turning to favor the Partisans. On 16 June 1944, the Treaty of Vis was signed between the Partisans and the Royal Government, officially making the Partisans the regular army of Yugoslavia. By the end of August, Josip Tito was appointed as the Chief-of-Staff of the Yugoslav Army in the Fatherland, although his Royalist rival Mihajlović and many Chetniks continued fighting their own resistance until their final defeat in the Battle on Lijevča field by a Croatian coalition.

As the Red Army continued their advance into the Balkans, Bulgaria left the Axis on September 9, and German troops abandoned Greece on October 12. Concurrently, Yugoslav Partisans shifted operations into Serbia, freed Belgrade on October 20 with Soviet help, and assisted the Albanian Resistance rout the Germans by November 29. By year-end, the Partisans controlled the eastern half of Yugoslavia and the Dalmatian coast, and were ready for a final westward offensive by late March 1945. In the meantime, the Red Army had also driven Army Group North out of most of the Baltic States and trapped the remainder on the Courland Peninsula in Latvia where the 18th and 16th German Armies, numbering over 250,000 men were trapped and would remain there till the end of the war.

The Soviets recovered from their defeat in Debrecen and advancing columns reached Budapest on December 29, 1944 and en-circled the city where over 188,000 Axis troops were trapped including many German Waffen-SS. The Germans held out until February 13, 1945 and the siege became one of the bloodiest of the war.

Invasion of Germany

Main articles: Vistula-Oder Offensive and Battle of Berlin

With the Balkans and most of Hungary cleared of German troops by late December 1944, the Soviets began a massive re-deployment of their forces to Poland for their upcoming winter offensive. Soviet preparations were still on going when Churchill asked Stalin to launch his offensive as soon as possible to ease German pressure in the West. Stalin agreed and the offensive was set for January 12, 1945. Konev’s armies attacked the Germans in southern Poland and expanded out from their Vistula River bridgehead near Sandomierz. On January 14, Rokossovskiy’s armies attacked from the Narew River north of Warsaw. Zhukov's armies in the center attacked from their bridgeheads near Warsaw. The combined Soviet offensive broke the defenses covering East Prussia, leaving the German front in chaos.

Zhukov took Warsaw by January 17 and by January 19, his tanks took Łódź. That same day, Konev's forces reached the German prewar border. At the end of the first week of the offensive, the Soviets had penetrated 160 kilometers (100 mi) deep on a front that was 650 kilometers (400 mi) wide. The Soviet onslaught finally halted on the Oder River at the end of January, only 60 kilometers (40 mi) from Berlin.

The Soviets had hoped to capture Berlin by mid-February but that proved hopelessly optimistic. German resistance, which had all but collapsed during the initial phase of the attack, had stiffened immeasurably. Soviet supply lines were over-extended. The spring thaw, the lack of air support, and fear of encirclement through flank attacks from East Prussia, Pommern and Silesia led to a general halt in the Soviet offensive. The newly created Army Group Vistula, under the command of Heinrich Himmler, attempted a counter-attack on the exposed flank of the Soviet Army but failed by February 24. This made it clear to Zhukov that the flank had to be secure before any attack on Berlin could be mounted. The Soviets then re-organized their forces, then struck north, cleared Pomerania, and then attacked the south and cleared Silesia of German troops. In the south, three German attempts to relieve the encircled Budapest garrison failed, and the city fell to the Soviets on February 13. Again, the Germans counter-attacked; Hitler insisting on the impossible task of regaining the Danube River. By March 16, the attack had failed, and the Red Army counter-attacked the same day. On March 30, they entered Austria and captured Vienna on April 13.

Hitler had believed that the main Soviet target for their upcoming offensive would be in the south near Prague and not Berlin and had sent the last remaining German reserves to defend that sector. The Red Army's main goal was in fact Berlin and by April 16 it was ready to begin its final assault on Berlin. Zhukov's forces struck from the center and crossed the Oder river but got bogged down under stiff German resistance around Seelow Heights. After three days of very heavy fighting and 33,000 Soviet soldiers dead, the last defenses of Berlin were breached. Konev crossed the Oder river from the South and was within striking distance of Berlin but Stalin ordered Konev to guard the flanks of Zhukov's forces and not attack Berlin, as Stalin had promised the capture of Berlin to Zhukov. Rokossovskiy’s forces crossed the Oder from the North and linked up with British Field Marshal Bernard Montgomery's forces in northern Germany while the forces of Zhukov and Konev captured Berlin.

By April 24, the Soviet army groups had encircled the German Ninth Army and part of the 4th Panzer Army. These were the main forces that were supposed to defend Berlin but Hitler had issued orders for these forces to hold their ground and not retreat. Thus, the main German forces, which were supposed to defend Berlin, were trapped southeast of the city. Berlin was encircled around the same time and as a final resistance effort, Hitler called for civilians, including teenagers and the elderly, to fight in the Volkssturm militia against the oncoming Red Army. Those marginal forces were augmented by the battered German remnants that had fought the Soviets in Seelow Heights. Hitler ordered the encircled Ninth Army under General Theodor Busse to break out and link up with the German Twelfth Army under General Walther Wenck. After linking up, the armies were to relieve Berlin, an impossible task. The surviving units of the Ninth Army were instead driven into the forests around Berlin near the village of Halbe where they were involved in particularly fierce fighting trying to break through the Soviet lines and reach the Twelfth Army. A minority managed to join with the Twelfth Army and fight their way west to surrender to the Americans. Meanwhile the fierce urban fighting continued in Berlin. The Germans had stockpiled a very large quantity of panzerfausts and took a very heavy toll on Soviet tanks in the rubble filled streets of Berlin. However, the Soviets employed the lessons they learned during the urban fighting of Stalingrad and were slowly advancing to the center of the city. German forces in the city resisted tenaciously, in particular the SS Nordland which was made of foreign SS volunteers, because they were ideologically motivated and they believed that they would not live if captured. The fighting was house-to-house and hand-to-hand. The Soviets sustained 360,000 casualties; the Germans sustained 450,000 including civilians and above that 170,000 captured. Hitler and his staff moved into the Führerbunker, a concrete bunker beneath the Chancellery, where on April 30, 1945, he committed suicide, along with his bride, Eva Braun.

End of the war in Europe

Winston Churchill, Franklin D. Roosevelt, and Joseph Stalin at the Yalta Conference in 1945.

Churchill, United States President Franklin D. Roosevelt, and Soviet Union leader Joseph Stalin arranged for post-war Europe at the Yalta Conference in February 1945. Their meeting resulted in many important resolutions such as the formation of the United Nations, democratic elections in Poland, borders of Poland moved westwards at the expense of Germany, Soviet nationals were to be repatriated and it was agreed that Soviet Union would attack Japan within three months of Germany’s surrender.

After Hitler's death (on April 30), Grand Admiral Karl Dönitz became leader of the German government but the German war effort quickly disintegrated. German forces in Berlin surrendered the city to Soviet troops on May 2, 1945. The German forces in Italy surrendered on May 2, 1945, at General Alexander's headquarters, and German forces in northern Germany, Denmark, and the Netherlands surrendered on May 4. The German High Command under Generaloberst Alfred Jodl surrendered unconditionally all remaining German forces on May 7 in Rheims, France. The western Allies celebrated "V-E Day" on May 8, since the final German surrender was signed in Berlin on that day. The Soviet Union celebrated "Victory Day" on May 9 due to time zone differences; the final cessation of German military activity happened at one minute past midnight by their clock. Some remnants of German Army Group Center continued resistance until May 11 or May 12.

Hideki Tojo, Prime Minister of Imperial Japan.

After World War I, the victorious Western powers adopted policies that recognized Japan as a colonial power. Many Japanese politicians and militarist leaders, such as Fumimaro Konoe and Sadao Araki, promoted the idea that Japan had a right to conquer Asia and unify it, under the rule of Emperor Hirohito.

Japan invaded Manchuria under the diplomatic pretext of the staged Mukden Incident in 1931, and converted Manchuria into the puppet state of Manchukuo in 1932. It invaded China in 1937 to bolster its meager stock of natural resources, to relieve Japan from population pressures and to extend its colonial realm to a wider area. The Japanese made initial advances but were stalled in the Battle of Shanghai. The city eventually fell to the Japanese in December 1937, with the capital city Nanjing. As a result, the Chinese Nationalist government, run by the Kuomintang party moved its seat to Wuhan and then to Chongqing for the remainder of the war. Conquered areas of China became subject to a harsh occupation, with many atrocities against civilians, most notably the Rape of Nanking. The Japanese Army also frequently used chemical weapons. Neither Japan or China officially declared war, for a similar reason — fearing declaration of war would alienate Europe and the United States, who might then cut off supplies badly needed to continue their war efforts.

In spring 1939, Soviet and Japanese forces clashed in Mongolia. The growing Japanese presence in the Far East was seen as a major strategic threat by the Soviet Union, and Soviet fear of having to fight a two front war was a primary reason for the Molotov-Ribbentrop Pact with the Nazis (other historians mention the Munich Agreement as a supposition to this pact). The Japanese invasion of Mongolia was repulsed by Soviet units under General Georgiy Zhukov. Following this battle, the Soviet Union and Japan were at peace until 1945. Japan looked south to expand its empire, leading to conflict with the United States over the Philippines and control of shipping lanes to the Dutch East Indies. The Soviet Union and Japan eventually signed a non-aggression pact in 1941. The Soviet Union focused on the west, with their eastern flank secured, while the Japanese directed their attention south, towards the British, Dutch, and American colonies of the South Pacific.

Japanese forces invaded French Indochina on September 22, 1940. The United States (after having renounced the U.S.-Japanese trade treaty of 1911), United Kingdom, Australia and the Netherlands (which controlled the oil of the Dutch East Indies), reacted in July 1941 by instituting embargoes on exports of natural resources to Japan. The western powers also began making loans to China and providing covert military assistance.

Japan was faced with the choice of withdrawing from China and Indochina, negotiating some compromise, buying what they needed somewhere else, or going to war to conquer territories that contained oil, iron ore, bauxite and other resources necessary for continued operations in China. Japan's leaders believed that the existing Allies were preoccupied with the war against Germany, and that the United States would not be war-ready for years and would compromise before waging full-scale war. Japan thus proceeded with its plans for the war in the Pacific by launching nearly simultaneous attacks on Malaya, Thailand, Hong Kong, Hawaii, the Philippines, and Wake Island.

For propaganda purposes, Japan's leaders stated that the goal of its military campaigns was to create the Greater East Asia Co-Prosperity Sphere. This, they claimed, would be a co-operative league of Asian nations, freed by Japan from European imperialist domination, and liberated to achieve autonomy and self-determination. In practice, occupied countries and peoples were subordinate to Japanese authority.

Main article: Second Sino-Japanese War

The Chinese Nationalist Army, under Chiang Kai-shek, and the Communist Chinese Army, under Mao Zedong, had been fighting a civil war since 1927, but agreed to a truce to fight the invading Japanese. Mao's forces were incorporated into the New Fourth Army and the Eighth Route Army, subordinate units within the Nationalist Army. Following the New Fourth Army Incident, the cooperation between the KMT and CCP fell apart. Conflict between Nationalist and Communist forces emerged long before the war; it continued after and, to an extent, even during the war, though less openly.

On December 3, 1941, the Imperial General Headquarters authorized general Yasuji Okamura to implement the sanko sakusen in North China.

Japan launched a major offensive in China following the attack on Pearl Harbor. The aim of the offensive was to take the strategically important city of Changsha, which the Japanese had failed to capture on two previous occasions. For the attack, the Japanese massed 120,000 soldiers under four divisions. The Chinese responded with 300,000 men, and soon the Japanese army was encircled and had to retreat.

Following the Changsha offensive, the war in China returned to the stalemate that had existed in 1940. The Chinese did not have the strength in terms of manpower or equipment to drive the Japanese out. The Japanese had taken heavy casualties as well, and were having trouble pacifying already conquered territory. The front lines changed little until the Japanese mounted a major offensive in early 1944.

In April 1944, the Japanese launched Operation Ichigo, to secure the railway route from Peking to Nanking, and to clear southern China of American airfields under the command of General Chennault The operation was successful in that it opened a continuous corridor from Peking to Indochina, and the airfields were forced to relocate inland. However it failed to destroy the army of Chiang Kai-shek, and the Americans soon acquired the Marianas, from which they could bomb the Japanese Home Islands.

Japanese offensives (1941–1942)

I praise the Army for cutting down like weeds large numbers of the enemy… – Hirohito

The US destroyer Shaw exploding during the Attack on Pearl Harbor, December 7, 1941.

On December 7, 1941, a Japanese carrier fleet launched a surprise air attack on Pearl Harbor. The raid destroyed most of the American aircraft on the island and knocked the main American battle fleet out of action (three battleships were sunk, and five more were heavily damaged, though only USS Arizona and USS Oklahoma were permanently lost, the other six battleships were repaired and eventually returned to service). Nevertheless, the four American aircraft carriers were at sea and escaped destruction. At Pearl Harbor, the main dock, supply, and repair facilities were quickly repaired. Furthermore, the base's fuel storage facilities, whose destruction could have crippled the Pacific fleet, were untouched. The attack united American public opinion to demand vengeance against Japan. The following day, December 8, the United States declared war on Japan as did the United Kingdom.

Simultaneously with the attack on Hawaii, the Japanese attacked Wake Island, an American territory in the central Pacific. The initial landing attempt was repulsed by the garrison of Marines, and fierce resistance continued until December 23. The Japanese sent heavy reinforcements, and the garrison surrendered when it became clear that no American relief force was coming.

Japan also invaded the Philippines, a U.S. Commonwealth, on December 8, 1941. American and Filipino forces, under General Douglas MacArthur, were forced to retreat to the Bataan Peninsula. Dogged resistance continued until April, buying precious time for the Allies. Following their surrender, the survivors were led on the Bataan Death March. Allied resistance continued for an additional month on the island fortress of Corregidor, until it too surrendered. General MacArthur, who had been ordered to retreat to Australia, vowed, "I shall return."

Less than 24 hours after the attack on Pearl Harbor, Japan invaded Hong Kong. The British colonies of Malaya, Borneo, and Burma soon followed, with Japan's intention of seizing the oilfields of the Dutch East Indies. Despite fierce resistance by Philippine, Australian, New Zealand, British, Canadian, Indian, and American forces, all these territories capitulated to the Japanese in a matter of months. Singapore fell to the Japanese on February 15. About 80,000 British Commonwealth personnel (along with 50,000 taken in Malaya) went into Japanese POW camps, representing the largest-ever surrender of British-led personnel. Churchill considered the British defeat at Singapore as one of the most humiliating British defeats of all time.

Disaster struck the British on December 10, 1941, when they lost two major capital ships, HMS Prince of Wales and HMS Repulse. Eighty-five Japanese bombers had attacked both ships and torpedo planes based in Saigon, and 840 UK sailors perished. Churchill was to say of the event, "In all of the war I have never received a more direct shock." ABDACOM naval forces were all but destroyed in the Battle of the Java Sea—the largest naval battle of the war up to that point — on February 28 through March 1, 1942. The joint command was wound up shortly afterwards; to be replaced by three Allied supreme commands in southern Asia and the Pacific.

In the six months after Pearl Harbor, the Japanese had achieved nearly all of their naval objectives. Their fleet of eleven battleships, ten carriers, eighteen heavy and twenty light cruisers remained relatively intact. They had seriously damaged or sunk all U.S. battleships in the Pacific. The British and Dutch Far Eastern fleets had been destroyed, and the Royal Australian Navy had been driven back to port. Their ring of conquests settled on a defensive perimeter of their choosing, extending from the Central Pacific to New Guinea to Burma. The only significant strategic force was the U.S. Pacific Fleet's four aircraft carriers.

Allies re-group and counterattack

Main articles: Pacific Ocean theater of World War II and South West Pacific theatre of World War II

The Allies were officially formed in the Declaration by United Nations on January 1, 1942. Soon afterwards, the American-British-Dutch-Australian Command (ABDACOM) was formed to unite Allied forces in South East Asia. It was the first Allied supreme command of the war.

More significantly, in April 1942, the US-British Combined Chiefs of Staff was formed, the highest military command for the western Allies during the war. The CCS was a body constituted from the British Chiefs of Staff Committee and the United States Joint Chiefs of Staff. Although it was responsible to the British and US governments, the CCS controlled forces from many different countries, in all theatres of war.

In early May 1942, the Japanese implemented Mo Sakusen (Operation Mo), a plan to take Port Moresby, New Guinea. The first stage was thwarted by the U.S. and Australian navies in the Battle of the Coral Sea. This was both the first battle fought between aircraft carriers, and the first battle where the opposing fleets never made direct visual contact. The American aircraft carrier Lexington was sunk and the Yorktown was severely damaged, while the Japanese lost the light carrier Shōhō and the large carrier Shōkaku suffered moderate damage. Zuikaku lost half of her air complement, and along with Shōkaku, was unable to participate in the upcoming battle at Midway. The battle was a tactical victory for the Japanese, as they inflicted heavier losses on the American fleet, but it was a strategic American victory, as the Japanese attack on Port Moresby was deflected, and both Zuikaku and Shōkaku would not be ready to participate in the upcoming battle of Midway the following month.

In April, the Doolittle Raid, the first Allied air raid on Tokyo, boosted morale in the United States and caused Japan to shift resources to homeland defense, but did little physical damage. The raid was unique in that 16 land-based B-25 Mitchell bombers took off from an aircraft carrier, USS Hornet.

Both sides viewed a decisive battle between aircraft carriers as inevitable, and the Japanese were confident in that they held a numerical advantage in heavy carriers of 10:3. They also had an excellent carrier-based aircraft in the Zero fighter. The Japanese sent a task force towards Midway Island, an outlier of the Hawaiian Islands, with the goal of drawing the remainder of the American fleet to battle.

On June 5, American carrier-based dive-bombers sighted the Japanese force and sank four of Japan's best aircraft carriers in the Battle of Midway, at the cost of the carrier Yorktown. This was a major victory for the United States and, as Admiral Isoroku Yamamoto predicted would happen six months after the Pearl Harbor attack, it marked the turning point of the war in the Pacific where the USA gained the initiative. American shipbuilding and aircraft production vastly outpaced the Japanese, and the Japanese fleet would never again enjoy such numerical superiority.

New Guinea and the Solomon Islands

Main articles: New Guinea campaign and Solomon Islands campaign

In July 1942, the Japanese attempted to take Port Moresby by land, along the Kokoda Track, a rugged, single-file path through the jungle and mountains. An under-strength, poorly trained and ill-equipped Australian brigade waged a fighting retreat against a 5,000-strong Japanese force.

On August 7, U.S. Marines began the Battle of Guadalcanal. For the next six months, U.S. forces fought Japanese forces for control of the island. Meanwhile, several naval encounters raged in the nearby waters, including the Battle of Savo Island, Battle of Cape Esperance, Naval Battle of Guadalcanal, and Battle of Tassafaronga.

In late August and early September, while battle raged on the Kokoda Track and Guadalcanal, an attack by Japanese marines at the eastern tip of New Guinea was defeated by Australian forces, in the Battle of Milne Bay. This was the first defeat for Japanese land forces during the Pacific War. On January 22, 1943, after a bitter battle at Gona and Buna, Australian and U.S. forces took back the major Japanese beachheads in eastern New Guinea, before American authorities declared Guadalcanal secure on February 9.

On June 30, the Allies launched Operation Cartwheel, a grand strategy for the South and South West Pacific, aimed at isolating the major Japanese base at Rabaul, before proceeding on an "island-hopping" campaign towards Japan. Three main objectives were identified: recapturing Tulagi and the Santa Cruz Islands; recapturing the north coast of New Guinea, and the central Solomon Islands and; the reduction of Rabaul and related bases.

By September, Australian and U.S. forces in New Guinea had captured the major Japanese bases at Salamaua and Lae. Soon afterwards they launched the Huon Peninsula, the Finisterre Range, Bougainville, and New Britain campaigns.

Island hopping campaign

Main article: Gilbert and Marshall Islands campaign

In November 1943, U.S. Marines won the Battle of Tarawa. This was the first heavily opposed amphibious assault in the Pacific theater. The high casualties taken by the Marines sparked off a storm of protest in the United States, where the large losses could not be understood for such a tiny and seemingly unimportant island. The Allies adopted a policy of bypassing some Japanese island strongholds and letting them "wither on the vine” cut off from supplies and troop reinforcements.

The Allied advance continued in the Pacific with the capture of the Marshall Islands before the end of February 1944. Some 42,000 U.S. Army soldiers and U.S. Marines landed on Kwajalein atoll on January 31. Fierce fighting occurred, and the island was taken on February 6. U.S. Marines next defeated the Japanese in the Battle of Eniwetok.

The U.S. strategic objective was to gain airbases within bombing range of the new B-29s on the Mariana Islands, especially Saipan, Tinian and Guam. Following Allied victories to the east at the Marshall and Gilbert Islands in late 1943 to early 1944, the US Navy pushed into the Central Pacific. The Japanese base at Truk was neutralized by a massive air raid on February 17 and 18, 1944. On June 11, the U.S. Naval fleet bombarded Saipan defended by 32,000 Japanese troops; 77,000 Marines started landing on the 15th, and the island was secure by July 9.

The Japanese committed much of their declining naval strength in the Battle of the Philippine Sea, but suffered severe losses in both ships and aircraft. After the battle, the Japanese aircraft carrier force was no longer militarily effective. With the capture of Saipan, Japan was finally within range of B-29 bombers.

Guam was invaded on July 21 and taken on August 10, but the Japanese fought fanatically. Mopping-up operations continued long after the Battle of Guam was officially over. The island of Tinian was invaded on July 24 and was conquered on August 1. This operation saw the first use of napalm in the war.

Return to the Philippines

General MacArthur's troops liberated the Philippines, landing on the island of Leyte on October 20. The Japanese had prepared a rigorous defense and used the last of their naval forces in a failed attempt to destroy the invasion force in the Battle of Leyte Gulf, October 23 through October 26, 1944, arguably the largest naval battle in history. This was the first battle that employed Japanese kamikaze attacks, HMAS Australia being the first Allied ship targeted by such an attack. The Japanese battleship Musashi, one of the two largest battleships ever built, was sunk by 19 torpedoes and 17 bombs.

In January 1945, the U.S. Sixth Army landed on Luzon, the main island of the Philippines. Manila was recaptured by March, but mopping up operations on Luzon and other islands continued until the end of the war.

Japanese home islands

Main articles: Battle of Iwo Jima and Battle of Okinawa

US Marines pass by a dead Japanese soldier during the Battle of Okinawa, 1945.

The United States captured Iwo Jima in February. The island was psychologically important because it was traditional Japanese territory, administered by the Tokyo prefecture. It was heavily defended with many underground entrenchments, but was eventually taken by Marines after they captured Mount Suribachi, a keystone of the defense. Iwo Jima proved invaluable because of its two airfields that were used for emergency landings for B29's, and because it was close enough to provide fighter escort that could reach the Japanese Home Islands.

With the subsequent capture of Okinawa (April through June), the U.S. brought the Japanese homeland within easier range of naval and air attack. The Japanese defended the island with ground forces, kamikazes, and with the one-way suicide mission of the battleship Yamato, which was sunk by American dive-bombers. Amongst dozens of other Japanese cities, Tokyo was firebombed, and about 90,000 people died from the initial attack. The dense living conditions around production centres and the wooden residential constructions contributed to the large loss of life. In addition, the ports and major waterways of Japan were extensively mined by air in Operation Starvation, which seriously disrupted the logistics of the island nation.

South-East Asia

The Japanese had captured most of Burma, severing the Burma Road by which the Western Allies had been supplying the Chinese Nationalists. This loss forced the Allies to create a large sustained airlift from India, known as "flying the Hump". Under the American General Joseph Stilwell, Chinese forces in India were retrained and re-equipped, while preparations were made to drive the Ledo Road from India to replace the Burma Road. This effort was to prove an enormous engineering task.

While the Americans steadily built the Ledo Road from India to China, in March 1944, the Japanese began their own offensive into India. This "Delhi Chalo" ('March to Delhi') was initiated by Netaji Subhas Chandra Bose, the commander of Indian National Army (a force comprising POWs from the British Indian Army who had been captured by the Japanese and had decided to join the war in an attempt to rid India of their colonial rulers, and thereby attain independence).

The Japanese attempted to destroy the main British and Indian forces at the Battle of Imphal, resulting in ferocious fighting. While the encircled allied troops were reinforced and resupplied by transport aircraft until fresh troops broke the siege, the Japanese, in part due to torrential rains, ran out of supplies and starved. The surviving forces eventually retreated losing 85,000 men, one of the largest Japanese defeats of the war.

During the monsoon from August to November 1944, the Japanese were pursued to the Chindwin River in Burma. With the onset of the dry season in early 1945, while the American and Chinese forces finally completed the Ledo Road, although too late to have any decisive effect, the British Fourteenth Army, consisting of Indian, British, and African units, launched an offensive into Central Burma. The Japanese forces were heavily defeated, and the Allies pursued them southward, taking Rangoon on May 2 (see Operation Dracula).

Submarine warfare

After the destruction of the Pacific fleet at Pearl Harbor, one of the few resources at the American Navy's disposal was her submarine fleet. President Roosevelt ordered the boats to conduct unconditional submarine warfare within hours of the commencement of hostilities.

Throughout 1944, Allied submarines and aircraft attacked Japanese merchant shipping and deprived Japan's industry of the raw materials it had gone to war to obtain. The main target was oil, and Japan ran almost dry by late 1944. In 1944, submarines sank over two million tons of cargo, while the Japanese were only able to replace less than one million tons.

U.S. submarines accounted for 56% of the Japanese merchantmen sunk; most of the rest were destroyed by planes at the end of the war, or were sunk by mines. U.S. submariners also claimed 28% of Japanese warships destroyed, including the carriers Taihō and Shōkaku during the Battle of the Philippine Sea. Furthermore, they played important reconnaissance roles, as at the battles of the Philippine Sea and Leyte Gulf (and, coincidentally, at Midway), when they gave accurate and timely warning of the approach of the Japanese fleet. Submarines operated from secure bases in Fremantle, Australia; Pearl Harbor; Trincomalee, Ceylon; and later Guam.

End of the war in Asia

The atomic bombings of Hiroshima & Nagasaki are the only nuclear attacks in history. Here, the mushroom cloud of the bomb Fat Man rises 18 km over Nagasaki on August 9, 1945 – the war in Asia & the Pacific is practically over.

Main articles: Potsdam Conference, Battle of Okinawa, Atomic bombings of Hiroshima and Nagasaki, Operation August Storm, and Surrender of Japan

The last Allied conference of World War II was held at the suburb of Potsdam, outside Berlin, from July 17 to August 2. During the Potsdam Conference, agreements were reached among the Allies on policies for occupied Germany. An ultimatum was issued calling for the unconditional surrender of Japan.

U.S. president Harry Truman decided to use the new atomic weapon to end the war. The battle for Okinawa had shown that an invasion of the Japanese mainland (planned for November) would result in large numbers of American casualties. The official estimate given to the Secretary of War was 1.4 to four million Allied casualties, though some historians dispute whether this would have been the case. Invasion would have meant the death of millions of Japanese soldiers and civilians, who were being trained as militia (see also Operation Downfall).

On August 6, 1945, a B-29 Superfortress, the Enola Gay, dropped a nuclear weapon dubbed Little Boy on Hiroshima, destroying the city. On August 9, a B-29 named Bockscar dropped the second atomic bomb, dubbed Fat Man, on the port city of Nagasaki.

On August 8 the Soviet Union, having renounced its nonaggression pact with Japan in April, attacked the Japanese in Manchuria, fulfilling its Yalta pledge to attack the Japanese within three months after the end of the war in Europe. 1.6 million Soviet soldiers made the attack. In less than two weeks, the Japanese army in Manchuria, consisting of over a million men, had been defeated by the battle-hardened Soviets. The Red Army moved into North Korea on August 18. Korea was subsequently divided at the 38th parallel into Soviet and U.S. zones.

The American use of atomic weapons against Japan and the Soviet invasion of Manchukuo prompted the prime minister to ask Emperor Hirohito to intervene to end the war. In his radio address to the nation, the Emperor did not mention the entry of the Soviet Union into the war, but in his "Rescript to the soldiers and sailors" of August 17, ordering them to cease fire and lay down arms, he stressed the relationship between Soviet entrance into the war and his decision to surrender, omitting any mention of the atomic bombs.

The end of the war hastened the independence of many British crown colonies (such as India) and Dutch territories (such as Indonesia) and the formation of new nations and alliances throughout Asia and Africa. The Philippines were granted their independence in 1946 as previously promised by the United States. France attempted and failed to regain control of its colonies in Indochina.

Poland's boundaries were re-drawn to include portions of pre-war Germany, including East Prussia and Upper Silesia, while ceding most of the areas taken by the Soviet Union in the Molotov-Ribbentrop partition of 1939, effectively moving Poland to the west. Germany was split into four zones of occupation, and the three zones under the Western Allies were reconstituted as a constitutional democracy. The Soviet Union's influence increased as they, with the tacit approval of the West, established hegemony over most of eastern Europe and incorporated parts of Finland and Poland into their new boundaries. This appeasement of Stalin by the West became known as the Western betrayal among the Soviet-dominated countries. Europe was informally split into Western and Soviet spheres of influence, which heightened existing tensions between the two camps and helped establish the Cold War.

To prevent (or at least minimize) future conflicts, the allied nations, led by the United States, formed the United Nations in San Francisco, California in 1945. One of the first actions of the United Nations was the creation of the State of Israel, partly in response to the Holocaust.

In 1947, U.S. Secretary of State George Marshall devised the "European Recovery Program", better known as the Marshall Plan. Effective from 1948 to 1952, it allocated 13 billion dollars for the reconstruction of Western Europe. Of Germany’s four zones of occupation, coordinated by the Allied Control Council, the American, British, and French zones joined in 1949 as the Federal Republic of Germany, and the Soviet zone became the German Democratic Republic. In Germany, economic suppression and denazification took place for several years. Millions of Germans and Poles were expelled from their homelands as a result of the territorial annexations in Eastern Europe agreed upon at the Yalta and Potsdam conferences. Mainstream estimates of German casualties from this process range one–two million. In the West, Alsace-Lorraine was returned to France, and the Saar area was separated from Germany and put in economic union with France. Austria was divided into four zones of occupation, which were united in 1955 to become the Republic of Austria. The Soviet Union occupied much of Central and Eastern Europe and the Balkans. In all the USSR-occupied countries, with the exception of Austria, the Soviet Union helped Communist regimes to power. It also annexed the Baltic countries Estonia, Latvia, and Lithuania.

In Asia, Japan was occupied by the U.S, aided by Commonwealth troops, until the peace treaty took effect in 1952. The Japanese Empire's government was dismantled under General Douglas MacArthur and replaced by a constitutional monarchy with the emperor as a figurehead. The defeat of Japan also led to the establishment of the Far Eastern commission, which set out policies for Japan to fulfill under the terms of surrender. In accordance with the Yalta Conference agreements, the Soviet Union occupied and subsequently annexed Sakhalin and the Kuril islands. Japanese occupation of Korea also ended, but the peninsula was divided between the U.S. and the Soviet Union, along 38th parallel. The U.S.-backed South Korea would fight the communist North Korea in the Korean War, with Korea remaining divided.

World War II was a pivotal point in China's history. Before the war against Japan, China had suffered nearly a century of intervention at the hands of various imperialist powers and was relegated to a semi-colonial status. However, the war greatly enhanced China's international status. The central government under Chiang Kai-shek was able to abrogate most of the unequal treaties China had signed in the past century, and China became a founding member of the United Nations and a permanent member of the Security Council. China also reclaimed Manchuria and Taiwan. Nevertheless, eight years of war greatly taxed the central government, and many of its nation-building measures adopted since it came to power in 1928 were disrupted by the war. Communist activities also expanded greatly in occupied areas, making post-war administration of these areas difficult. Vast war damages and hyperinflation thereafter demoralized the populace, along with the continuation of the Chinese Civil War between the Kuomintang and the Communists. Partly because of the severe blow his army and government had suffered during the war against Japan, the Kuomintang, along with state apparatus of the Republic of China, retreated to Taiwan in 1949 and in its place the Chinese communists established the People's Republic of China on the mainland.

Estimates for the total casualties of the war vary, but most suggest that some 60 million people died in the war, including about 20 million soldiers and 40 million civilians. Many civilians died because of disease, starvation, massacres, genocide. The Soviet Union lost around 27 million people during the war, about half of all World War II casualties. Of the total deaths in World War II, approximately 85% were on the Allied side (mostly Soviet and Chinese) and 15% on the Axis side. One estimate is that 12 million civilians died in Holocaust camps, 1.5 million by bombs, 7 million in Europe from other causes, and 7.5 million in China from other causes. Figures on the amount of total casualties vary to a wide extent because the majority of deaths were not documented.

Concentration camps and slave work

Victims of the holocaust.

The Holocaust was the killing of approximately six million European Jews, as well as another six million others who were deemed "unworthy of life" (including the disabled and mentally ill, Soviet POWs, homosexuals, Freemasons, Jehovah's Witnesses, and the Roma) as part of a program of deliberate extermination planned and executed by the National Socialist government in Germany led by Adolf Hitler. About 12 million forced laborers, most of whom were Eastern Europeans, were employed in the German war economy inside the Nazi Germany.

In addition to the Nazi concentration camps, the Soviet Gulag, or labor camps, led to the death of citizens of occupied countries such as Poland, Lithuania, Latvia, and Estonia, as well as German prisoners of war (POW) and even Soviet citizens themselves who had been or were thought to be supporters of the Nazis. Sixty percent of Soviet POWs died during the war. Vadim Erlikman puts it at 2.6 million Soviet POWs that died in German Captivity. Richard Overy gives the number of 5.7 million Soviet POW and out of those 57% died or were killed which is 3.6 million. The survivors on their return to the USSR were treated as traitors (see Order No. 270).

Japanese POW camps also had high death rates, many were used as labour camp. According to the findings of the Tokyo tribunal, the death rate of Western prisoners was 27.1% (American POWs died at a rate of 37%), seven times that of POW's under the Germans and Italians The death rate of Chinese was much larger as, according to the directive ratified on 5 August 1937 by Hirohito, the constraints of international law were removed on those prisoners. Thus, if 37,583 prisoners from the UK, 28,500 from Netherlands and 14,473 from USA were released after the surrender of Japan, the number for the Chinese was only 56.

According to a joint study of historians featuring Zhifen Ju, Mark Peattie, Toru Kubo, and Mitsuyoshi Himeta, more than 10 million Chinese were mobilized by the Japanese army and enslaved by the Kōa-in for slave labor in Manchukuo and north China. The U.S. Library of Congress estimates that in Java, between 4 and 10 million romusha (Japanese: "manual laborer"), were forced to work by the Japanese military. About 270,000 of these Javanese laborers were sent to other Japanese-held areas in South East Asia. Only 52,000 were repatriated to Java, meaning that there was a death rate of 80%. According to Mitsuyoshi Himeta, at least 2.7 million died during the Sankō Sakusen implemented in Heipei and Shantung by General Yasuji Okamura.

On February 19, 1942, Roosevelt signed Executive Order 9066, leading to the internment of thousands of Japanese, Italians, German Americans, and some emigrants from Hawaii who fled after the bombing of Pearl Harbor for the duration of the war. 150,000 Japanese-Americans were interned by the U.S. and Canadian governments, as well as nearly 11,000 German and Italian residents of the U.S.

Chemical and bacteriological weapons

Despite the international treaties and a resolution adopted by the League of Nations on 14 May 1938 condemning the use of toxic gas by Japan, the Imperial Japanese Army frequently used chemical weapons. Because of fears of retaliation, however, those weapons were never used against Westerners but only against other Asians judged "inferior" by the imperial propaganda. According to historians Yoshiaki Yoshimi and Seiya Matsuno, the authorization for the use of chemical weapons was given by specific orders (rinsanmei) issued by Hirohito himself. For example, the Emperor authorized the use of toxic gas on 375 separate occasions during the invasion of Wuhan, from August to October 1938.

The biological weapons were experimented on human beings by many units incorporated in the Japanese army, such as the infamous Unit 731, integrated by Imperial decree in the Kwantung army in 1936. Those weapons were mainly used in China and, according to some Japanese veterans, against Mongolians and Soviet soldiers in 1939 during the Nomonhan incident. According to documents found in the Australian national archives in 2004 by Yoshimi and Yuki Tanaka, cyanide gas was tested on Australian and Dutch prisoners in November 1944 in the Kai islands.

Bombings

Massive aerial bombing by both Axis and Allied air forces took the lives of hundreds of thousands of civilians. Anglo-American bombing of German cities claimed up to 600,000 civilian lives. For the first and so far only time, nuclear weapons were used in combat: two atomic bombs released by the United States over Japan devastated Hiroshima and, three days later, Nagasaki. The number of total casualties in these bombings has been estimated to 200,000.

War trials

From 1945 to 1951, German and Japanese officials and personnel were prosecuted for war crimes. The most senior German officials were tried at the Nuremberg Trials, and many Japanese officials at the Tokyo War Crime Trial and other war crimes trials in the Asia-Pacific region. Many other minor officials were convicted in minor trials.
