The eastern Bosnia area, which during the Independent State of Croatia (NDH), included the area of its eleven districts was in the period of 1942 the main rebel center. In the first half of 1942 the rebel forces, which were largely composed of local Serbian population, controlled the central part of the eastern Bosnian area. Their main opponent were the NDH institutions which by the end of 1941 lost control over the whole territory of eastern Bosnia with the exception of its northern part and the city of Sarajevo, due to the underdevelopment of their administrative apparatus. As a result, the German Army actively engaged in the combat against the rebel forces to counteract their influence and renew the work of NDH institutions. As opposed to that, the Italian Army, which supervised over the southern district up to the town of Višegrad, which was the most important eastern Bosnia traffic center after Sarajevo, had a different attitude towards these events than the German Army, which manifested itself in the fact that the Italian squad in Višegrad accepted the Chetniks as allies. This fact led to the redefinition of allied relations in eastern Bosnia in 1942 between the Italian Army on the one hand and the German Army and the NDH Administration on the other hand, since the Italian army provided protection to the Chetniks who were considered by the German military institutions and the NDH authorities as their opponents. This opposing relationship was followed up by the conflict between these four listed military-political factors against the partisans who were a threat to all. By suppressing the majority of Partisan forces from eastern Bosnia in mid-1942, this area became a relatively quiet in the second half of 1942, where the only obstacle for stabilization of the NDH Administration were the Chetniks who were in an alliance with the Italian army. However, in the interests of NDH, the German Army also attempted to establish a co-operation with the Chetniks, but this cooperation was spatially and temporally limited, and had never been carried out in the same intensity as it was between the Chetniks and the Italian Army.
