 Another Chetnik commander to cooperate with the Soviets was Captain Predrag Raković of the Second Ravna Gora Corps, whose men participated in the capture of Čačak, where they captured 339 soldiers of the "Russisches Schutzkorps Serbien" (whom they turned over to the Soviets).Raković apparently had a written agreement with the local Soviet commander, placing himself and his men under Soviet command in return for recognition that they were Mihailović's men.After a protest from Tito to Marshal Fyodor Tolbukhin, commander of the front, Keserović's and Raković's cooperation came to an end.
