was housed on the 35th and 36th floors of the International Building,
Rockefeller Center, New York City After
World War II began (and over the objections of
Sir Stewart Menzies, wartime head of
British intelligence) now-Prime Minister
Winston Churchill sent Stephenson to the United States on 21 June 1940, to covertly establish and run
British Security Coordination (BSC) in New York City, over a year before U.S. entry into the war. His deputy at BSC was the Australian-born MI6 intelligence officer
Dick Ellis, who has been credited with writing the blueprint for William Donovan's
Coordinator of Information and the
Office of Strategic Services. Ellis wrote an Historical Note for William Stevenson's 1976 biography of Stephenson,
A Man Called Intrepid. BSC was registered by the State Department as a foreign entity. It operated out of Room 3603 at
Rockefeller Center and was officially known as the British Passport Control Office from which it had expanded. BSC acted as the administrative headquarters more than the operational one for the
Secret Intelligence Service (MI6) and the
Special Operations Executive (SOE) and was a channel for communications and liaison between US and British security and intelligence organisations. Stephenson's initial directives for BSC were to • investigate enemy activities; • institute security measures against sabotage to British property; and • organize American public opinion in favour of aid to Britain. Later this was expanded to include "the assurance of American participation in secret activities throughout the world in the closest possible collaboration with the British". Stephenson's official title was British
Passport Control Officer. His unofficial mission was to create a secret British intelligence network throughout the western hemisphere, and to operate covertly and broadly on behalf of the British government and the
Allies in aid of winning the war. Stephenson was soon a close adviser to Roosevelt, and suggested that he put Stephenson's good friend
William J. "Wild Bill" Donovan in charge of all U.S. intelligence services. Donovan founded the U.S.
Office of Strategic Services (OSS), which in 1947 would become the
Central Intelligence Agency (CIA). As senior representative of British intelligence in the
Western Hemisphere, Stephenson was one of the few persons in the hemisphere who were authorized to view raw
Ultra transcripts of German
Enigma ciphers that had been
decrypted at Britain's
Bletchley Park facility. He was trusted by Churchill to decide what Ultra information to pass along to various branches of the U.S. and Canadian governments. in Bermuda, home to British Imperial Censorship during the war, and to Sir William Stephenson after the war. While it was still neutral, agreement was made for all trans-Atlantic mails from the U.S. to be routed through the
British colony of
Bermuda, 640 miles off the
North Carolina coast. Airmails carried by both British and American aircraft were landed at
RAF Darrell's Island and delivered to 1,200 censors of
British Imperial Censorship, part of BSC, working in the
Princess Hotel. All mail, radio and telegraphic traffic bound for Europe, the U.S. and the Far East were intercepted and analyzed by 1,200 censors, of
British Imperial Censorship, part of
British Security Coordination (BSC), before being routed to their destination with no indication that they had been read. With BSC working closely with the FBI, the censors were responsible for the discovery and arrest of a number of Axis spies operating in the US, including the
Joe K ring. was an IBM Telex machine adapted by Pat Bayly to operate on a one time cypher, allowing secure communication among the Allies throughout the war. It continued to be used in peacetime until the 1970s. He hired hundreds of people, mostly Canadian women, to staff his organization and covered much of the expense out of his own pocket. His employees included secretive communications genius
Benjamin deForest "Pat" Bayly and future advertising wizard
David Ogilvy. Stephenson employed
Amy Elizabeth Thorpe, codenamed CYNTHIA, to seduce
Vichy French officials into giving up Enigma ciphers and secrets from their Washington embassy. At the height of the war Bayly, a
University of Toronto professor from
Moose Jaw, created the
Rockex, the fast secure communications system that would eventually be relied on by all the Allies. Located in
Whitby, Ontario, this was the first such training school in North America. Estimates vary, but between 500 and 2,000 British, Canadian and American covert operators were trained there from 1941 to 1945. Reports indicate that
Camp X graduates worked as "secret agents, security personnel, intelligence officers, or psychological warfare experts, serving in clandestine operations. Many were captured, tortured, and executed; survivors received no individual recognition for their efforts." ==Honours==
