By September 1993, CANBAT 1 was relocated from Sector West to Sector South (northern Dalmatia and Lika). The UNPFROFOR mandate in Croatia expired on 31 March 1995, and the United Nations Security Council adopted Resolution 981 establishing the United Nations Confidence Restoration Operation in Croatia (UNCRO) instead. Sector West was captured by the HV in Operation Flash in early May 1995, with no resistance from UN peacekeepers. The main axis of the first day's HV advance was the Zagreb–Belgrade motorway, as anticipated by the planners of Operation Backstop.
