The Mosul offensive (2015) was an offensive launched by Kurdish Peshmerga forces on 21 January 2015, with the objective of severing key ISIL supply routes to Mosul, Iraq, and to recapture neighboring areas around Mosul. The effort was supported by US-led coalition airstrikes. The Iraqi Army was widely expected to launch the planned operation to retake the actual city of Mosul in the Spring of 2015, but the offensive was postponed to October 2016, after Ramadi fell to ISIL in May 2015.
