The High Command Trial (officially, The United States of America vs. Wilhelm von Leeb, et al.), also known initially as Case No. 12 (the 13 Generals' Trial), and later as Case No. 72 (the German high command trial: Trial of Wilhelm von Leeb and thirteen others), was the last of the twelve trials for war crimes the U.S. authorities held in their occupation zone of Germany in Nuremberg after the end of World War II. These twelve trials were all held before U.S. military courts, not before the International Military Tribunal, but took place in the same rooms at the Palace of Justice. The twelve U.S. 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 accused in this trial were high-ranking generals of the German Wehrmacht (including two field marshals of the Army, one field marshal of the air force and one general admiral), some of whom had been members of the High Command of Nazi Germany's military forces. They were charged with having participated in or planned or facilitated the execution of the numerous war crimes and atrocities committed in countries occupied by the German forces during the war.
The judges in this case, heard before Military Tribunal V-A, were the American John C. Young (presiding judge), Winfield B. Hale, and Justin W. Harding. The Chief of Counsel for the Prosecution was Telford Taylor. The indictment was filed on November 28, 1947; the trial lasted from December 30 that year until October 28, 1948.
The accused faced four charges of having committed war crimes and crimes against humanity:
Crimes against peace by waging aggressive war against other nations and violating international treaties.
War crimes by being responsible for murder, ill-treatment and other crimes against prisoners of war and enemy belligerents.
Crimes against humanity by participating or ordering the murder, torture, deportation, hostage-taking, etc. of civilians in military-occupied countries.
