British agents working in Albania during the war fed the Albanian resistance fighters with false information that the Allies were planning a major invasion of the Balkans and urged the disparate Albanian groups to unite their efforts. In August 1943, the Allies convinced communist and Balli Kombëtar leaders to sign the Mukje Agreement that would coordinate their guerrilla operations. The two groups eventually ended all collaboration, however, over a disagreement on the postwar status of Kosovo. The communists supported returning the region to Yugoslavia after the war with the hope that Tito would cede Kosovo back to Albania peacefully, while the nationalist Balli Kombëtar advocated keeping the province.
