On April 19, 1943, the Warsaw ghetto uprising began after German troops and police entered the ghetto to deport its surviving inhabitants. By May 16, 1943, the Germans had crushed the uprising and left the ghetto area in ruins. Surviving ghetto residents were deported to concentration camps or killing centers.
Between July 22 and September 12, 1942, the German authorities deported or murdered around 300,000 Jews in the Warsaw ghetto. SS and police units deported 265,000 Jews to the Treblinka killing center and 11,580 to forced-labor camps. The Germans and their auxiliaries murdered more than 10,000 Jews in the Warsaw ghetto during the deportation operations. The German authorities granted only 35,000 Jews permission to remain in the ghetto, while more than 20,000 Jews remained in the ghetto in hiding. For the at least 55,000-60,000 Jews remaining in the Warsaw ghetto, deportation seemed inevitable.
