Friedrich Paulus
Hitler gave orders to examine the possibility of a prisoner exchange with the Soviets for Stalin's son Yakov Dzhugashvili, who had been captured by the Germans on 16 July 1941. Stalin refused to exchange him either for Raubal or for Friedrich Paulus, and said "war is war." Raubal was detained in Moscow's jails and was released by the Soviets on 28 September 1955, and returned to Austria.
