 In May 1942 , Đurišić attacked and defeated the last significant Partisan detachment in Montenegro . In June 1942 , Đurišić collaborated with the Ustaše in Foča in south @-@ eastern Bosnia . After being forced out of Serbia by the Germans , Mihailović arrived in Montenegro as the Italians and Chetniks were fighting the Partisans . Mihailović was accompanied by his staff and a British Special Operations Executive ( SOE ) liaison officer . He eventually established his base in the village of Gornje Lipovo , a few miles from Đurišić 's headquarters at Kolašin . Mihailović and his staff had few troops and relied on Đurišić for protection . Soon after Mihailović arrived in Montenegro , Đurišić told Mihailović 's SOE liaison officer that he was available to act independently and in defiance of Mihailović . Đurišić and the other Chetnik commanders in Montenegro nominally recognised Mihailović as their supreme commander but they rarely obeyed him .
