The Kragujevac massacre was the murder of Serbs , Jewish and Roma men and boys in Kragujevac , Serbia , by German Wehrmacht soldiers on 20 and 21 October 1941 . All males from the town between the ages of sixteen and sixty were assembled by German troops and members of the collaborationist Serbian Volunteer Command ( SDK ) and Serbian State Guard ( SDS ) , including high school students , and the victims were selected from amongst them . On 29 October 1941 , Felix Benzler , the plenipotentiary of the German foreign ministry in Serbia , reported that 2,300 people were executed . Later investigations by the post-war Yugoslavian government came up with between 5,000 and 7,000 people executed , although these figures were never proven reliable . Subsequently , Serbian and German scholars have agreed on the figure of 2,778
