Lt. Col. Duncan Chaplin Lee (died 1988) was confidential assistant to Maj. Gen. William ("Wild Bill") Donovan, founder and director of the Office of Strategic Services (OSS), World War II-era predecessor of the CIA, during 1942-46. Lee is identified in Venona as the Soviet double agent operating inside OSS under the cover name "Koch,"[1] making him the most senior alleged source the Soviet Union ever had inside American intelligence.
As an OSS officer, Lee served as head of the China section of SI, the Secret Intelligence Branch.[2] While an officer, according to Soviet courier Elizabeth Bentley, Lee -- reportedly a descendant of Confederate Gen. Robert E. Lee[3] -- covertly furnished her with information on “anti-Soviet work by OSS” and other topics of interest to Moscow,[4] which was technically an ally (in Europe) following the collapse of the Nazi-Soviet pact. As Bentley told the FBI when she defected in 1945, she transferred this information to her Soviet handlers.[5]
In her August 1948 appearance before the House Committee on Un-American Activities (HCUA), Bentley testified that Lee furnished her “various types of information,” which she then turned over to her Soviet handlers, including, in Bentley’s words, details on “whether the OSS had spotted any of our people [Communists]” in that organization. As the Germans were retreating from Eastern Europe and the Balkans, Bentley reported Lee as identifying groups working with the OSS to keep Soviet troops out of their countries. Lee also told her, she said, that “something very secret was going on” at Oak Ridge, Tenn., an apparent reference to the Manhattan Project.[6]
Lee, a former Rhodes scholar who attended Oxford University with fellow OSS staffer Donald Niven Wheeler (identified in Venona as the Soviet agent operating in OSS under cover name "Izra"[7]), repeatedly denied Bentley's allegations, under oath[8], but acknowledged he and his wife knew Bentley as a family friend (albeit under an assumed name)[9] and that he had met her several times while an OSS officer in various locations, as well as with Mary Price (identified in Venona as the Soviet agent operating in the office of columnist Walter Lippmann under the code names "Dir"[10] and "probably" "Arena"[11]), and veteran NKVD rezident Jacob Golos, identified in Venona as Zvuk ("Sound"). Lee said he eventually realized that Bentley held "communistic"[12] views and terminated their relationship[8], but never reported these meetings as regulations would seem to require.[13]
Lee’s testimony elicited from one HCUA member, Rep. John McDowell (R-Penn.), the comment: For the first time “since the conspiracy of Aaron Burr, a high officer of the Army has been accused publicly of the violation of the Articles of War, which he must certainly realize the penalties and the punishment.”[14] Lee was in fact never indicted much less convicted of perjury or any other crime despite the accusations of his alleged co-conspirator Bentley[15]. According to Bentley, Lee refused to meet with her in the presence of others when divulging classified information to her and refused to give her any classified documents; there was as a consequence virtually no credible evidence to corroborate Bentley’s accusations[16]. Bentley herself was not an effective witness. Only one of the dozens of people she denounced were ever convicted of any crime arising out of her accusations, but only a few were even prosecuted. Many freely admitted their espionage in public hearings once the statute of limitations had run, and most of those she named were independently proved guilty by the testimony of other eyewitnesses, if not eventually by the Venona files.[17].
The VENONA decrypts that refer to Koch only confirm that Bentley passed on to Moscow the information she claimed to have received from Lee and do not in themselves provide independent evidence to corroborate Bentley’s accusation that Lee was the source of that information[18]. A 1944 Venona decrypt confirms that Lee tipped off Bentley about Donovan sending him on a secret mission to China.[19]
According to the Moynihan Commission, "It would ... appear from the VENONA messages that Duncan Chaplin Lee, Special Assistant to OSS Director William J. Donovan, was a Soviet agent."[20]
Lee went on to have a successful career as a lawyer in the private sector[21]. Lee continued to represent clients such as Claire Chennault and Whiting Willaurer. In 1949, following the fall of China to the communists, Lee represented a CIA-front company in the Hong Kong and UK courts in a successful effort to keep a large fleet of transport aircraft in Hong Kong, once owned by the Nationalist Chinese government, from being turned over to the new communist Chinese regime after its recognition by the British.[22] Lee joined insurance giant American International Group in 1953, rising to serve as AIG’s chief in-house lawyer in New York City prior to his retirement in 1974[23]. He subsequently moved to Toronto with his Canadian wife, Frances Lee Smith, where he died in 1988[24].
