As the allied armies approached, a prisoner re-location from Mittelbau-Dora to Bergen-Belsen camp was stalled due to Allied bombing of the rail lines. 1,016 prisoners were herded into a barn near Gardelegen and burned alive. Most died from the burning; those who tried to escape were shot. The US 102nd Infantry Division discovered the atrocity on April 15th, 1945, before the SS had time to cover it up. The 102nd Commander, Major General Keating, ordered the citizens of Gardelegen to recover the bodies and inter them in a cemetery on the premises, to be maintained in perpetuity.  Link. Map
