At the beginning of
World War II in Yugoslavia, Rogatica and all of eastern
Bosnia along with Sandžak in
Serbia became part of the
Independent State of Croatia. The military units of the Independent State of Croatia in eastern Bosnia consisted of regular units of the
Croatian Home Guard and members of the local Muslim population who were recruited into units of
Ustaše militia that distinguished itself in the persecution of Serbs from the beginning of the war. During the war, Rogatica was captured many times by different belligerents. The first capture by combined Chetnik-Partisan forces occurred on 6 September 1941. The rebel forces that attacked Rogatica had around 400 men in total, consisting of 240 Partisans and 160 Chetnik forces commanded by Aćim Babić. The rebels forced the town's garrison, consisting of the Croatian Home Guard, Ustaše and the local Muslim Militia, to flee toward
Mesići. That afternoon, Muslim Militia forces commanded by Zulfo Dumandžić recruited reinforcement in
Višegrad and with support of Ustaše and Croatian Home Guard returned to recapture Rogatica, burning
Zagorice along the way and massacring its population. Approximately 100 civilians were killed during this assault. Ustaše commander Marko Vrkljan began taking Serb men and women as hostages. Some were immediately killed, while most survived until rebels captured the town in October 1941. One of the most important consequences of this first attack was additional fortification, both in the town and around it. The main aim of the Chetnik-Partisan offensive on Rogatica,
Knežina and
Žepa in October 1941 was to connect rebel-controlled territories in eastern Bosnia and western Serbia. Muslims from Rogatica were evacuated to
Sarajevo following an order issued on 11 October. In mid-October 1941, Rogatica was completely surrounded by Partisan and Chetnik forces, forcing its garrison to be supplied by aeroplanes that quickly became an easy target for the besieging forces. == Forces ==
