On October 3, General Tadeusz Bór-Komorowski signed the capitulation of the remaining Polish forces (Warszawski Korpus Armii Krajowej or Home Army Warsaw Corps) in the German headquarters in the presence of General Erich von dem Bach-Zelewski.
Many soldiers, fearing German atrocities in captivity, chose to blend into the civilian population, escape Warsaw among them and continue the fight later.
During the Warsaw Uprising the Red Army stood on the other bank of the Vistula River and only elements from the Polish 1 Armia Wojska Polskiego attempted to make a crossing and received artillery support.
The decision to start the Uprising was rushed several times: first on 20 July, when plans for Operation Tempest were changed to include Warsaw (after the series of reports on aggressive actions by Soviets toward Home Army units in the eastern territories), then on 31 July when exaggerated reports of approaching Russian forces convinced some decision makers that if they did not start the Uprising soon it would be too late to aid the Russians and 'make a stand'.
Most civilians were not killed and many were released into the country west of Warsaw, but some were sent to concentration camps or subjected to slave labour.
