Death marches (Holocaust)
Death marches (Todesmärsche in German) refer to the forcible movements of prisoners in Nazi Germany. They occurred at various points during the Holocaust, including in 1939 in the Lublin province of Poland, in 1942 in Ukraine, and between Autumn 1944 and late April 1945 from Nazi concentration camps and prisoner of war camps near the front, to camps inside Germany away from front lines and Allied forces to remove evidence from concentration camps and to prevent the repatriation of prisoners of war.
