Wikipedia: During the war, Dahl supplied intelligence from Washington to Stephenson and his organisation known as British Security Coordination, which was part of MI6. He was revealed in the 1980s to have been serving to help promote Britain's interests and message in the United States and to combat the "America First" movement, working with such other well-known officers as Ian Fleming and David Ogilvy. Dahl was once sent back to Britain by British Embassy officials, supposedly for misconduct ? "I got booted out by the big boys," he said. Stephenson promptly sent him back to Washington?with a promotion to Wing Commander. Towards the end of the war, Dahl wrote some of the history of the secret organisation and he and Stephenson remained friends for decades after the war.
