According to a history cobbled together by the
National Park Service, the unit was conceived as an Army/Navy installation to gather information from prisoners who had been captured or surrendered and were brought to the United States for questioning. Germany had superior technology, particularly in rocketry and submarines, and the information that was gleaned from interrogations gave the United States an advantage going into the Cold War and the space age.
In the beginning, the prisoners were mostly U-boat crew members who had survived the sinking of their submarines in the Atlantic Ocean. As the war progressed, P.O. Box 1142 shifted its attention to some of the most prominent scientists in Germany, many of whom surrendered and gave up information willingly, hoping to be allowed to stay in the United States.
The prisoners stayed at Fort Hunt for as little as two or three weeks and as long as nine months. They were held incommunicado; when they had told everything they knew, they were transferred to regular POW camps elsewhere in the United States, and the Red Cross was then notified of their capture. After the war, some returned to Germany, and some stayed in the United States, slipping into the fabric of American life.
