 In September 1943 , the Italians capitulated and the Germans occupied Montenegro , establishing an area command ( German : Feldkommandantur 1040 ) under Generalmajor ( Brigadier ) Wilhem Keiper . Soon after , the German Special Envoy in Belgrade Hermann Neubacher , Milan Nedić , and the German Military Commander in south @-@ east Europe General Hans Felber arranged for Đurišić to be released . Neubacher had developed a plan to establish a union between Serbia and Montenegro and submitted it to Foreign Minister Joachim von Ribbentrop in October 1943 . Đurišić was an important part of this plan . He was well regarded by the Chetniks and pro @-@ Chetnik populace in Montenegro , and Stanišić and Đukanović had been killed . Neubacher , Nedić and Felber believed Đurišić could be used to fight the Partisans in Montenegro and help form closer relations between Serbia and Montenegro . Although Neubacher 's plan did not gain Hitler 's approval , Đurišić received supplies including arms and ammunition from the Germans and in November 1943 he returned to Montenegro to fight against the Partisans . At this time he established closer ties with Dimitrije Ljotić , whose Serbian Volunteer Corps ( SDK ) provided him with weapons , food , typewriters , and other supplies . He also worked with Nedić , who promoted him to the rank of lieutenant colonel , and appointed him assistant to the commander of the SDK . According to Pajović , Đurišić was promoted in early to mid @-@ 1944 by the Yugoslav government @-@ in @-@ exile on the advice of Mihailović .
