	From 11–14 October 1942, the Military Commander in Serbia launched a large-scale Axis offensive against Mihailović's Chetniks under command of Keserović in the region around Kriva Reka on Kopaonik mountain. The operation was a punitive expedition aimed against Mihailović's Chetniks, the chief target of German commanders who wanted to secure control of Serbia before important battles in North Africa.
