The Warsaw Ghetto was the largest of all ghettos established by the Nazis. At its height, as many as 460,000 Jews were imprisoned there, in an area of 840 acres, with an average of 9.2 persons per room, barely subsisting on meager food rations.
Abraham Lewin kept a diary of his life there before the entire ghetto was liquidated.
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.
