The Partisan defeat of the Chetniks during the Battle of the Neretva, which routed the Chetnik forces from the Neretva and Drina rivers, largely ended this genocidal assault by March 1943. According to German verified data from the territory within their zone, in six east Bosnian and four central Bosnian districts, 8,400 Croats and 24,400 Muslims were killed by Chetnik forces, making a total of 32,800 people.
