In the closing phase of the Second World War, the SS took prisonders out of concentration camps that were about to be liberated and forced them into transports moving on foot or by train for days or weeks to reach other camps. Many people didn't survive these transports, anyone who could no longer walk was murdered by the guards. In the final months of the war, the Mauthausen concentration camp was the destination for death marches. In April 1945, Hungarian Jews were forced to walk from Mauthausen to Gunskirchen on a death march.
