The Einsatzgruppen trial (officially, The United States of America vs. Otto Ohlendorf, et al.) was the ninth of the twelve trials for war crimes and crimes against humanity that the US authorities held in their occupation zone in Germany in Nuremberg after the end of World War II. These twelve trials were all held before US military courts, not before the International Military Tribunal. They took place in the same rooms at the Palace of Justice. The twelve US trials are collectively known as the "Subsequent Nuremberg trials" or, more formally, as the "Trials of War Criminals before the Nuremberg Military Tribunals" (NMT). The case The Einsatzgruppen were SS mobile death squads, operating behind the front line in Nazi-occupied Eastern Europe. From 1941 to 1945, they murdered around 2 million people; 1.3 million Jews, up to 250,000 Romani, and around 500,000 so-called "partisans", people with disabilities, political commissars, Slavs, homosexuals and others. The 24 defendants in this trial were all commanders of these Einsatzgruppen units and faced charges of war crimes and crimes against humanity. The tribunal stated in its judgment: The judges in this case, heard before Military Tribunal II-A, were Michael Musmanno (presiding judge and Naval officer) from Pennsylvania, John J. Speight from Alabama, and Richard D. Dixon from North Carolina. The Chief of Counsel for the Prosecution was Telford Taylor; the Chief Prosecutor for this case was Benjamin B. Ferencz.
