They were held by the American Military Tribunal, without a jury, but instead by a panel of seven men, one of whom was versed in international military law.[5] The prosecution was different from most trials, in that the burden of proof was on the defense.[6] The charges to be carried out by the United States Military were against Germans such as camp guards, some SS units and medical personnel, who had taken part in war crimes against allied nationals.[7] The Dachau Trials consisted of 465 trials from not only the Dachau concentration camp, but also Flossenbürg concentration camp, Mauthausen-Gusen concentration camp complex, Nordhausen concentration camp, Buchenwald concentration camp, and Mühldorf concentration camp complex and consisted of four main categories of charges: main camp offense, subsidiary camp offenses, atrocities against downed fliers, and then a catchall category mainly consisting of details about the Malmedy Massacre.[8] On December 13, 1947[9] when the trials adjourned, roughly 1200 defendants had been tried with roughly a 73% conviction rate.[10]
