The Warsaw Uprising (Powstanie Warszawskie) was a World War II struggle by the PolishHome Army (Armia Krajowa) to liberate Warsaw from German occupation. The Uprising began on August 1, 1944, as part of a nationwide rebellion, Operation Tempest. It was intended to last for only a few days until the Soviet Army would reach the city. The Soviet advance stopped short, however, while Polish resistance against the German forces continued for 63 days (until October 2).
