Tito's Partisans fought the Germans more actively during this time. Tito and Mihailović had a bounty of 100,000 Reichsmarks offered by Germans for their heads. While officially remaining mortal enemies of the Germans and the Ustaše, the Chetniks were known for making clandestine deals with the Italians. The Second Enemy Offensive was a coordinated Axis attack conducted in January 1942 against Partisan forces in eastern Bosnia. The Partisan troops once again avoided encirclement and were forced to retreat over the Igman mountain near Sarajevo.
