The evacuation of the Janowska camp began in November 1943. As the Germans attempted to destroy the traces of mass murder (Aktion 1005), they forced the prisoners to open the mass graves and burn the bodies in Lesienicki forest. On November 19, 1943, inmates staged an uprising against the Nazis and a mass escape attempt. A few succeeded in escaping, but most were recaptured and killed. The SS staff and their local auxiliaries murdered at least 6,000 Jews who had survived the uprising killings, as well as Jews in other forced labor camps in Galicia, at the time of the Janowska camp's liquidation.
