The Ritchie Boys, part of the U.S. Military Intelligence Service (MIS) at the War Department, were an organization of soldiers in World War II with sizable numbers of German-Austrian recruits who were used primarily for interrogation of prisoners on the front lines and counter-intelligence in Europe. Trained at secret Camp Ritchie in Washington County, Maryland, many of the total 22,000 service men and women were German-speaking immigrants to the United States, often Jews, who fled Nazi persecution.[1][2] In addition to interrogation and counter-intelligence they were also trained in psychological warfare in order to study and demoralize the enemy, and served as prosecutors and translators in the Nuremberg trials.[3]
The parent organization of the Ritchie Boys, the MIS, was commanded in Washington by Brigadier General Hayes Adlai Kroner for most of the war.[4]
