On Friday 4 August 1995, with a massive Croatian military force poised to attack the Serb-held Krajina region in central Croatia, Karadžić announced he was removing General Ratko Mladić from his commandant post and assuming personal command of the VRS himself. Karadžić blamed Mladić for the loss of two key Serb-held towns in western Bosnia that had recently fallen to the Croats, and he used the loss of the towns as the excuse to announce his surprise command structure changes. General Mladić was demoted to an "adviser". Mladić refused to go quietly, claiming the support of the Bosnian Serb military and the people. Karadžić countered by attempting to pull political rank as well as denouncing Mladić as a "madman", but Mladić's popular support forced Karadžić to rescind his order on 11 August.
