Book on OSShttp://www.amazon.ca/World-War-II-Tragedy-Slovakia/dp/0971748209
This is a true account of a secret Office of Strategic Services (forerunner of the CIA) mission into Slovakia in the fall of 1944. A national uprising against a pro-German government was underway in the small country when the OSS, led by two U.S. Navy Lieutenants (in uniform!), sent the DAWES team into Slovakia on two flights of B-17's in September and October. The planes were forced to land on a grass airfield with German SS units only a few miles away and converging on the rebel capital where Lt. Holt Green had his OSS headquarters. Green and his men had been rounding up downed American airmen, as well as giving weapons training to Slovak Partisan units. Additionally the OSS was collecting order of battle intelligence on the Germans.
When the SS units overran the rebel capital three weeks later, the Slovaks and the OSS, plus a British intelligence team, were forced to flee into the mountains. In what became the coldest winter in a half century, the OSS hiked through waist-deep snow just ahead of a German Abwehr (counterintelligence) unit. Major Erwein Graf Thun-Hohenstein, an Austrian nobleman, was the relentless Abwehr commander intent on capturing the Anglo-American intelligence agents. He finally tracked them to a small hunting cabin where he captured them in a surprise attack.
In Berlin, SS leader Heinrich Himmler ordered the prisoners sent to Mauthausen concentration camp in Austria where they were tortured and finally shot.
