The Grossaktion Warsaw ("Great Action") was the Nazi code name for the deportation and mass murder of Jews from the Warsaw Ghetto during the summer of 1942, beginning on 22 July. During the Grossaktion, Jews were terrorized in daily round-ups, marched through the ghetto, and assembled at the Umschlagplatz station square for what was called in the Nazi euphemistic jargon "resettlement to the East". From there, they were sent aboard overcrowded Holocaust trains to the extermination camp in Treblinka.
