On 11 February 1945, at the conclusion of the Yalta Conference, the United States and United Kingdom signed a Repatriation Agreement with the USSR. British and U.S. civilian authorities ordered their military forces in Europe to deport to the Soviet Union millions of former residents of the USSR (some of whom collaborated with the Germans), including numerous persons who had left Russia and established different citizenship many years before.
