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.
