Oberkommando des Heeres
Early in 1942 Strik-Strikfeldt was transferred to the "Oberkommando des Heeres" (OKH) "War Booty Collection Centre" office in Angerburg, East Prussia, to sort through captured Russian military papers and documents for the "Fremde Heere Ost" ("Foreign Armies East") of the Army General Staff. In the spring and summer he worked briefly with Gehlen and Claus von Stauffenberg.
