After the Warsaw Ghetto Uprising was crushed in 1943, Rabbi Shapira was taken to the Trawniki work camp near Lublin. Although offered the opportunity to escape from the concentration camp, he apparently refused. Following the Jewish uprising in the Treblinka death camp (August 2, 1943) and in Sobibor extermination camp (October 14, 1943), there was increasing concern among the Nazi authorities that there would be further outbreaks of violence at other concentration camps. For this reason, Aktion Erntefest (Operation Harvest Festival) was launched. During this operation, carried out on November 3, 1943, all the remaining Jews in Trawniki, including Rabbi Shapira, were shot to death.
