After the 1941 split between the Partisans and the Chetniks in Serbia, the Chetnik groups in central, eastern, and northwestern Bosnia found themselves caught between the German and Ustaše (NDH) forces on one side and the Partisans on the other. In early 1942 Chetnik Major Jezdimir Dangić approached the Germans in an attempt to arrive at an understanding, but was unsuccessful, and the local Chetnik leaders were forced to look for another solution. The Chetnik groups were in fundamental disagreement with the Ustaše on practically all issues, but they found a common enemy in the Partisans, and this was the overriding reason for the collaboration which ensued between the Ustaše authorities of the Independent State of Croatia and Chetnik detachments in Bosnia.
