An armed uprising against the German occupiers of Warsaw by the Home Army (AK), lasting from August 1 to October 2, 1944. During the fighting, the occupation authorities expelled the civilian population from the city in order to facilitate operations against the insurrectionists. Civilians were mostly directed to a transit camp in Pruszków, from where a significant proportion were later deported to conscript labor camps in the Third Reich or to concentration camps. In August and September more than 13,000 people, including 1,500 children and youths, were sent to Birkenau. They were directed to the camp and went through the complete registration procedure with the exception of the tattooing of numbers. The majority were soon transferred to camps in the depths of the Reich as part of the preliminary evacuation of Auschwitz that was already underway, and forced to labor in German industry.
