Reginald Augustine served in the Army Air Corps during World War II. In 1944, he was assigned to the Alsos Mission, the Manhattan Project’s counterintelligence mission in Europe to determine how far Nazi Germany had gotten on the path to building an atomic bomb. Augustine served under Colonel Boris Pash, and accompanied the Mission’s scientists in France and Germany. He also escorted some of the German scientists captured by the Allies to Farm Hall in England, including Otto Hahn. Augustine describes how the Mission also investigated German scientists, and recovered the world atomic standards. He also explains some of the logistics of the Alsos Mission and how they endeavored to keep from both the Germans and the Soviets the true nature of their work.
