 Despite his possession of Mihailović 's instructions , Đurišić initially had minimal influence on the non @-@ communist elements of the Montenegrin resistance and was unable to develop an effective strategy against the Italians or Partisans in the months after his return to Montenegro . In early 1942 , his Chetnik detachment became more active against local Muslims , especially in eastern Montenegro and the Sandžak . The Partisans occupied Kolašin in January and February 1942 , and turned against all real and potential opposition ; they killed about 300 people and threw their corpses into pits they called the " dogs ' cemetery " . Because of this and other examples of communist terror , some Montenegrins turned against the Partisans . On 23 February , Đurišić captured Kolašin and held it as a Chetnik bastion until May 1943 . Chetnik terror against political opponents intensified following the town 's capture and manifested in show trials and mass executions that lasted until late June .
