By the end of the Siege of Breslau, 50% of the old town, 90% of the western and southern and 10–30% of the northern and northeastern quarters of the city had been destroyed. 40,000 inhabitants, including forced labourers, lay dead in the ruins of homes and factories. After a siege of nearly three months, "Fortress Breslau" surrendered on 7 May 1945. It was one of the last major cities in Germany to fall.
