Some senior officers were taken to Moscow and used for propaganda purposes. Some of them joined the National Committee for a Free Germany. Some, including Paulus, signed anti-Hitler statements that were broadcast to German troops. Paulus testified for the prosecution during the Nuremberg Trials. He remained in the Soviet Union until 1952, then moved to Dresden in East Germany. General Walther von Seydlitz-Kurzbach offered to raise an anti-Hitler army from the Stalingrad survivors, but the Soviets did not accept. It was not until 1955 that the last of the 5-6,000 survivors were repatriated (to West Germany).
