After the war ended, Wagner was taken prisoner by the Americans. He was extradited to Yugoslavia in 1947. There, he was put on trial before the military tribunal of the 3rd Yugoslav Army from 29 May to 6 June 1947 in Zrenjanin. It is not precisely known for what he was indicted. However, his orders for the mass executions of civilians in 1941 and later on reportedly played a role in his conviction. Found guilty of the charges, he was sentenced to death by firing squad and executed on 27 June 1947.[2]
