The Mittelbau camps held about 60,000 prisoners of The Holocaust between August 1943 and March 1945 . Conservative estimates assume that at least 20,000 inmates perished at the Mittelbau-Dora concentration camp . In early April 1945 , an unknown number of prisoners perished in death marches following the evacuation of prisoners from Mittelbau camps to Bergen-Belsen concentration camp in northern Germany
