On 4 August 1995, with a huge Croatian military force poised to attack the Serb-held region in central Croatia, Radovan Karadžić announced he was removing Mladić from his post and assuming personal command of the VRS himself. Karadžić blamed Mladić for the loss of two key Serb towns in western Bosnia that had recently fallen to the Croatian army, and he used the loss of the towns as an excuse to announce his surprising changes in the command structure. Mladić was demoted to an "adviser". He refused to go quietly, claiming the support of both the Bosnian Serb military as well as the people. Karadžić countered by denouncing Mladić as a "madman" and attempting to remove his political rank, but Mladić's obvious popular support forced Karadžić to rescind his order on 11 August. His actions during the war led to many dubbing him "The Butcher of Bosnia".
