​Memories of a POW camp outside Washington, D.C.

"P.O. BOX 1142" . . . an ordinary-sounding address for a place that played an extraordinary role during the Second World War. Seth Doane has been digging into its past:

It may seem hard to believe, but an open field in Alexandria, Va. -- a mere 13 miles from Washington, D.C. -- was once a top-secret military site.

Now all that is left are some stories and old pieces of cinderblock.

"It was pretty intentionally wiped clean and gotten rid of," said Brandon Bies, a history buff and National Park Service Ranger, who has spent the last eight years trying to uncover the hidden history of this place.

It's a journey that led him into the past -- and to 94-year-old Rudy Pins.

Doane asked Pins, "How was it to live with a secret like that?"

"Well, you get used to it," he replied. "Your fellow soldiers had the same secret."

Today, Pins is finally free to talk about his time as a U.S. Army intelligence officer at this prisoner-of-war camp during World War II.

"It was a secret installation for the interrogation of POWs -- Japanese, Italian and German, but mainly German," he said. He had no idea beforehand that it existed. Very few knew of the classified camp, code-named "P.O. Box 1142," located in Alexandria, even though 3,400 high-ranking prisoners of war were interrogated there between 1942 and 1945.

After the war, buildings were bulldozed, records were sealed, and those who knew anything about P.O. Box 1142 were sworn to secrecy -- including the German-born, Jewish Rudy Pins.

Doane asked, "What did the Nazis, what did Hitler do to your family?"

"Destroyed it. Humiliated it," he replied.

His parents were executed in the Holocaust.

On his balcony overlooking Honolulu, Pins showed Doane pictures of his brother and the family he left when he fled Germany in 1934. As a 14-year-old refugee, he was raised by American foster parents in Ohio.

"It was sad, but I don't know whether I had the full grasp and meaning of it -- and maybe that was good," Pins said.

His first-hand knowledge of Germany and its language made him an ideal recruit for U.S. Army Intelligence. At age 24 he started interrogating German POW's at the camp -- a secret part of Fort Hunt.

"I used to sit across from enemy soldiers who in combat would've killed me, and I probably would've killed them," he said. "My job was to get as much useful information as possible."

"You were face-to-face with the forces that destroyed your family?"

"They were the enemy. They were treated as the enemy. But you can't let your emotions get away from you. You also have a job to do."

Ranger Bies said, "It's an amazing story to try and think about what was going through the minds of these German-born Jewish American interrogators as they were sitting face-to-face, with someone who might have been responsible for interning relatives of theirs in a concentration camp.

On June 15, 1944, a captured Germany U-Boat commander, Werner Henke -- fearing he would be turned over to the British, who sought him as a war criminal -- attempted to escape from P.O. Box 1142. Henke vaulted an inner, 10-foot-high fence at Enclosure A and made a run for the main wire. He was shot and killed as he scaled the second wall.

Bies' quest to uncover what happened here all started with a chance encounter in 2006. A fellow Ranger had given a tour of the old military base Fort Hunt, and referenced some sort of secret activities that the Park Service thought had happened on these grounds.

"Someone raised their hand and said, 'My next-door neighbor used to be an interrogator here at Fort Hunt, and I'm sure he'd love to talk to you,'" said Bies.
