While working there, Vassall provided thousands of classified documents on British naval policy and weapons development (British radar, torpedoes, anti-submarine equipment, etc) to the Soviet Union. For years, Vassall’s cover was completely untraceable and he kept supplying documents to the Soviet Union. However, his secrecy came to light when a senior member of KGB, Anatoli Golitsin, defected to the CIA and identified Vassall as a potential spy. Upon hearing this, Vassall put a break on his work and handed in the camera that he used to photograph classified documents. In June 1962, another KGB officer defected to the CIA. The one thing that was different about this member, Yuri Nosenko, was he was a Soviet spy recruiter and identified Vassall as a spy. In September 1962, Vassall resumed his work as a spy, unaware that his cover was blown. He was quickly arrested and gave a full confession to everything that he did. The next month, he was sentenced to 18 years in prison. However Vassall only served 10 years and was released in 1972. In 1975, Vassal released an autobiography entitled Vassall: An Autobiography of a Spy. John Vassall died on November 18th,
