Beginning in 1944 the entire range of OSS planning documents on the postwar occupation of Germany were supplied to KGB head General [[Pavel Fitin]] in Moscow through Wheeler. Wheeler was considered the most active operative within the Perlo group. His complicity in espionage was corroborated by information exhumed from the NKVD archives in the 1990s. Wheeler appears in [[Venona]] as a Soviet source under the cover name "Izra". | Beginning in 1944 the entire range of OSS planning documents on the postwar occupation of Germany were supplied to KGB head General [[Pavel Fitin]] in Moscow through Wheeler.
