Between 16 May and 27 June, 131,641 Jews were deported from northern Transylvania. Wiesel, his parents and sisters—older sisters Hilda and Beatrice and seven-year-old Tzipora—were among them. On arrival Jews were "selected" for the death or forced labour; to be sent to the left meant work, to the right, the gas chamber. Sarah and Tzipora were sent to the gas chamber. Hilda and Beatrice survived, separated from the rest of the family. Wiesel and Chlomo managed to stay together, surviving forced labour and a death march to another concentration camp, Buchenwald, near Weimar. Chlomo died there in January 1945, three months before the 6th Armored Division of the United States Army arrived to liberate the camp.
