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 accused were 24 former SS leaders who, as commanders of the Einsatzgruppen of the Security Police and the SD, bore responsibility for the crimes committed by the Einsatzgruppen in the occupied Soviet Union. The indictment was based on the Einsatzgruppen reports of more than a million victims. 
The trial ended without acquittals: 14 defendants were sentenced to death, two were sentenced to life imprisonment and five were sentenced to prison terms ranging from 10 to 20 years. One accused committed suicide before the start of the trial, one dropped out of the trial due to illness, and another was released after serving the pre-trial detention. In 1950, the U.S. High Commissioner for Germany, John J. McCloy, taking into account the recommendations of the "Peck Panel", commuted ten of the 14 death sentences against those imprisoned in Landsberg in the Einsatzgruppe trial, ten sentences were converted into prison sentences. Of these, four death sentences were commuted to life imprisonment and six prison sentences were reduced to ten or twenty-five years. Four death sentences were carried out on June 7, 1951. The prison sentences of other prisoners were also shortened. The last three prisoners in the Einsatzgruppe trial were released from prison in May 1958.
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:
... in this case the defendants are not simply accused of planning or directing wholesale killings through channels. They are not charged with sitting in an office hundreds and thousands of miles away from the slaughter. It is asserted with particularity that these men were in the field actively superintending, controlling, directing, and taking an active part in the bloody harvest.
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. The indictment was filed initially on July 3 and then amended on July 29, 1947, to also include the defendants Steimle, Braune, Haensch, Strauch, Klingelhöfer, and von Radetzky. The trial lasted from September 29, 1947, until April 10, 1948.
- Crimes against humanity through persecutions on political, racial, and religious grounds, murder, extermination, imprisonment, and other inhumane acts committed against civilian populations, including German nationals and nationals of other countries, as part of an organized scheme of genocide.
- War crimes for the same reasons, and for wanton destruction and devastation not justified by military necessity.
- Membership of criminal organizations, the SS, the Sicherheitsdienst (SD), or the Gestapo, which had been declared criminal organizations previously in the international Nuremberg Military Tribunals.
All defendants were charged on all counts. All defendants pleaded "not guilty". The tribunal found all of them guilty on all counts, except Rühl and Graf, who were found guilty only on count 3. Fourteen defendants were sentenced to death. However, only four of them were executed. Nine of those condemned had their sentences reduced. Another, Eduard Strauch, couldn't be executed since he had been transferred to Belgian custody after his conviction.

The presiding judge, Michael Musmanno, explained his rationale for sentencing while testifying at the Frankfurt Auschwitz trials in the 1960s. He had chosen to impose death sentences in all cases where the defendant had actively participated in murder and failed to present mitigating circumstances. For example, although Erwin Schulz confessed to presiding over the execution of 90 to 100 men in Ukraine, he received a 20-year sentence since he had protested an order to exterminate all Jewish women and children, and immediately resigned when he was unable to get the order retracted. Superior orders was rejected as a defense.
Of the 14 death sentences, only four were carried out; the others were commuted to prison terms of varying lengths in 1951. In 1958, all convicts were released from prison.
Quotes from the judgment
The Nuremberg Military Tribunal in its judgement stated the following:
[The facts] are so beyond the experience of normal man and the range of man-made phenomena that only the most complete judicial inquiry, and the most exhaustive trial, could verify and confirm them. Although the principal accusation is murder, ... the charge of purposeful homicide in this case reaches such fantastic proportions and surpasses such credible limits that believability must be bolstered with assurance a hundred times repeated.
... a crime of such unprecedented brutality and of such inconceivable savagery that the mind rebels against its own thought image and the imagination staggers in the contemplation of a human degradation beyond the power of language to adequately portray.
The number of deaths resulting from the activities with which these defendants have been connected and which the prosecution has set at one million is but an abstract number. One cannot grasp the full cumulative terror of murder one million times repeated.
It is only when this grotesque total is broken down into units capable of mental assimilation that one can understand the monstrousness of the things we are in this trial contemplating. One must visualize not one million people but only ten persons – men, women, and children, perhaps all of one family – falling before the executioner's guns. If one million is divided by ten, this scene must happen one hundred thousand times, and as one visualizes the repetitious horror, one begins to understand the meaning of the prosecution's words, "It is with sorrow and with hope that we here disclose the deliberate slaughter of more than a million innocent and defenseless men, women, and children."
