Brothers Tuvia, Alexander, and Asael Bielski headquarter their partisan brigade in the Naboliki forest. Their numbers continue to grow as more and more Jews escaping from nearby ghettos find their way to the group. They establish a more permanent camp with diversified workshops that provide services to members of other partisan groups as well as their own.
Concerned about the recent Jewish uprisings, Himmler orders the liquidation of all remaining Jews in the Lublin District of the Generalgouvernement. Operation "Harvest Fest" takes place on two days in November 1943. More than 40,000 Jewish prisoners at Majdanek, Trawniki, Poniatowa and smaller camps in the district are murdered in mass shootings.
Some of the remaining Jews in the ghetto are deported to Sobibor, and the rest--approximately 4,000 people--are killed.
Under German occupation, Jews in Italy are subject to deportation. Some 8,000 Italian Jews are rounded up and deported to Auschwitz-Birkenau from areas under Nazi control.
Jewish prisoners plot and launch an armed revolt at Sobibor. They kill SS and Ukrainian camp guards and flee but are pursued by Nazi forces who ultimately capture and execute most escapees. Sobibor soon ceases operation and Nazi forces dismantle the camp and attempt to conceal its existence.
