 Đurišić maintained contact with Lukačević, who at that time had begun to attack the Germans in Herzegovina with his own forces. Đurišić considered the possibility of joining Lukačević in fighting the Germans in anticipation of an Allied landing. However, because Lukačević was quickly defeated and no Allied landing occurred, Đurišić remained tied to the Germans. German intelligence closely tracked Đurišić's communications and movements, and German commands continued to make use of his forces. The Germans counted Đurišić's Chetniks as part of Army Group E in a survey of available forces dated 16 November 1944. In the survey, German forces in Montenegro at that time were estimated at 47,000 soldiers, including Đurišić's 10,000 Chetniks. On 21 October 1944, the Partisans took the Grahovo garrison after a five-day battle. On 6 November, the Partisans surrounded Cetinje, which was defended by the Germans, Black Shirts, and about 600 Chetniks. On 8 November, the Germans and Chetniks in Cetinje were reinforced with a formation of 800 – 1,000 Chetniks led by Đurišić, which eventually succeeded in breaking through the Partisan blockade.
