 According to Tomasevich , the killing of the Montenegrin Chetniks by the Partisans at Kočevski Rog was an " act of mass terror and brutal political surgery " similar to that carried out by the Chetniks earlier in the war . It was partly an act of revenge for the mass terror carried out by the Chetniks against the Partisans and pro @-@ Partisan segments of the population and partly to stop the Chetniks from continuing an armed struggle against the communists , perhaps with Western assistance . Less than a quarter of the force that began with Đurišić in Montenegro , and other Chetniks who joined him during the journey north and west , survived . A few weeks later , Drljević , who had fled to Austria , was discovered by followers of Đurišić and killed . Đurišić was one of the most able Yugoslav Chetnik leaders ; his fighting skills were respected by his allies and opponents .
