When was Warsaw evacuated?

Warsaw was evacuated during World War II primarily in late 1944, particularly during the Warsaw Uprising, which lasted from August 1 to October 2, 1944. The population faced mass evacuations as the city was devastated by fighting and subsequent destruction by the German forces. After the uprising was suppressed, large portions of the population were forced to leave, and many were deported. The city was largely abandoned and left in ruins by the end of the war in 1945.
