 Some of Đurišić 's troops escaped and travelled west . Some were killed by Partisan forces , who were to the south of their intended withdrawal route west to Slovenia . The majority , left without a leader , were integrated into Drljević 's Montenegrin National Army and withdrew towards the Austrian border . Portions of both groups were later captured in Slovenia by the Partisans . About 1 @,@ 000 of Đurišić 's Chetniks crossed into Austria but were forced to return to Yugoslavia , where some were killed by the Partisans near the Yugoslav – Austrian border . Most were taken to southern Slovenia , where they were killed and their bodies thrown into deep abysses in the Kočevski Rog area .
