against the Soviet Union in 1941 to 1945, Gehlen's FHO collected much tactical military intelligence about the Red Army, and much strategic political intelligence about the Soviet Union. Understanding that the Soviet Union would defeat and occupy the Third Reich, Gehlen ordered the FHO intelligence files copied to microfilm; the FHO files proper were stored in watertight drums and buried in various locations in the Austrian Alps. They amounted to fifty cases of German intelligence about the Soviet Union, which were at Gehlen's disposal for sale to western intelligence services. Meanwhile, as of 1946, when the Soviets consolidated their hegemony and sphere of influence in Central, Eastern, and Southeastern Europe as agreed at the Potsdam Conference of 1945 and demarcated with what became known as the Iron Curtain, the Western Allies of World War II, the U.S, Britain, and France had no sources of covert information within the countries in which the occupying Red Army had vanquished the Wehrmacht.

The American Army recognised his potential value as a spymaster with great knowledge of Soviet forces and anticommunist intelligence contacts in the Soviet Union. In exchange for his own liberty and the release of his former subordinates (also prisoners of the US Army), Gehlen offered the Counter Intelligence Corps access to the FHO's intelligence archives and to his intelligence gathering abilities aimed at the Soviet Union, known later as the Gehlen Organization. Boker removed his name and those of his Wehrmacht command from the official lists of German prisoners of war, and transferred seven former FHO senior officers to join Gehlen. The FHO archives were unearthed and secretly taken to Camp King, ostensibly without the knowledge of the camp commander. By the end of summer 1945, Captain Boker had the support of Brigadier General Edwin Sibert, the G2 (senior intelligence officer) of the U.S. Twelfth Army Group, who arranged the secret transport of Gehlen, his officers and the FHO intelligence archives, authorized by his superiors in the chain of command, General Walter Bedell Smith (chief of staff for General Eisenhower), who worked with William Donovan (former OSS chief) and Allen Dulles (OSS chief), who also was the OSS station-chief in Bern. On 20 September 1945, Gehlen
