The city also endured heavy Allied and Soviet air raids. Those who survived and could not escape had to face the Soviet Army, which captured the heavily damaged city on 30 March 1945, followed by large-scale rape and looting. In line with the decisions made by the Allies at the Yalta and Potsdam conferences, the city was integrated with Poland. The remaining German residents of the city who had survived the war fled or were expelled to postwar Germany. The city was repopulated by ethnic Poles; up to 18 percent (1948) of them had been deported by the Soviets in two major waves from Polish areas annexed by the Soviet Union, such as the eastern portion (Kresy) of pre-war Poland.
