On 22 May 1945, General Reinhard Gehlen surrendered to the Counter Intelligence Corps (CIC) of the U.S. Army, in Bavaria, and was taken to Camp King, near Oberursel, and there interrogated by Captain John R. Boker.
The FHO archives in the control of Gehlen were unearthed and secretly taken to Camp King, ostensibly without the knowledge of the camp commander.
