At the Conference, the Allied leaders confirmed their previous commitment to the removal of German populations from Poland, Czechoslovakia, and Hungary; which the governments of those countries had already begun to put into effect. The three Allies at Potsdam were convinced that the transfer of these German populations should be completed as soon as possible. They emphasized that the transfers should proceed in an orderly and humane manner. However, eventually up to two million German civilians were killed during the expulsions.
