Soviet subjects who had volunteered for the German Army "Ostlegionen" and/or "Waffen SS" units were forcibly repatriated. These included Russian Cossacks of the XVth SS Cossack Cavalry Corps with their relatives, who were transported from the Western occupation zones of Allied-occupied Austria to the Soviet occupation zones of Austria and Allied-occupied Germany. Among those handed over were White émigré-Russians who had never been Soviet citizens, but who had fought for Nazi Germany against the Soviets during the war, including General Andrei Shkuro and the "Ataman" of the Don Cossack host Pyotr Krasnov. This was done despite the official statement of the British Foreign Office policy after the Yalta Conference, that only Soviet citizens who had been such after 1 September 1939, were to be compelled to return to the Soviet Union or handed over to Soviet officials in other locations (see the Repatriation of Cossacks after World War II).
