Two of the most highly publicised trials concerned the activities of German forces during the Battle of the Bulge in late 1944. In the Malmedy massacre trial, 73 members of the Waffen-SS were found guilty of summarily executing 84 American prisoners of war during the attack. In another trial, former German commando Otto Skorzeny and nine officers from the Panzer Brigade 150, were found not guilty of breaching the rules of war contrary to the Hague Convention of 1907 for wearing American military uniforms in a false flag operation, Operation Greif.
