 On 10 May 1943 , Oberstleutnant ( Lieutenant Colonel ) Heinz , commander of the 4th Regiment of the Brandenburg Division , met Đurišić at Kolašin with the intent of engaging him to help the Germans against the Partisans . Đurišić said he was willing to do this , and once the Partisans were defeated he said he would be ready to fight alongside the Germans on the Russian Front . During the meeting , Đurišić told Heinz that Mihailović had left Kolašin at the end of 1942 and that he refused to accept Mihailović 's current policy . Đurišić said Mihailović had been distracted by propaganda and was over @-@ rated , and described him as " an unsteady visionary wandering through the land " . Đurišić also said Josip Broz Tito and his Partisans were the only serious enemy . On 11 May 1943 , Heinz submitted a proposal to General der Infanterie ( Lieutenant General ) Rudolf Lüters , the German Commanding General in Croatia , regarding the Chetniks who had been " legalised " by the Italians . He suggested the Germans also " legalise " Đurišić 's Chetniks and use them to disarm " non @-@ legalised " Chetniks groups . Heinz also proposed that after the Partisans had been destroyed , the Germans " legalise " only weak detachments of Đurišić 's Chetniks . Subsequent events indicate Heinz 's approach to Đurišić may not have been authorised by his superiors and that his suggestions were not acted upon .
