SS-Hauptsturmfuehrer Kramer and 44 other Nazi SS guards who had been in charge of Bergen-Belsen camp were tried by a British military court at Lueneburg. The trial lasted from 17 September to 17 November 1945. The prosecution case was based on the grounds that Allied nationals, who had been ‘captured by surrender or extradition or otherwise,’ had been killed there. The prosecution council established that the actions constituted war crimes. Thirty of those on trial were found guilty. Those sentenced to death appealed to the convening officer, Field Marshal Montgomery. All the appeals for clemency were rejected. Ten, including Kramer, the camp doctor and female SS leaders, were hanged on 13 December 1945. The other 20 found guilty were sentenced to varying terms of imprisonment.
