By July 1944, the Red Army was deep into Polish territory and pursuing the Nazis toward Warsaw. The Polish government-in-exile in London gave orders to the underground Home Army (AK) to try to seize control of Warsaw before the Red Army arrived. Thus, on 1 August 1944, as the Red Army was nearing the city, the Warsaw uprising began. The armed struggle, planned to last 48 hours, was partially successful, however, it went on for 63 days. Eventually, the Home Army fighters and civilians assisting them were forced to capitulate. They were transported to PoW camps in Germany, while the entire civilian population was expelled. Polish civilian deaths are estimated at between 150,000 and 200,000.
