Counterintelligence: Operation Showdown

Counterintelligence can be described as activities designed to prevent or thwart spying, intelligence gathering, and sabotage by an enemy or other foreign entity. This guide provides books, articles, reports, websites, and videos on the subject.

Operation Showdown

Operation Showdown occurred in the early 1980's and targeted the East German Intelligence Service, utilizing a Navy civilian employee as a Double Agent.   In November 1983, East German physicist Alfred Zehe was arrested in Boston and later pleaded guilty to espionage.


Bill Tanner, a double agent working for the FBI and the Naval Investigative Service, began a sting operation by walking into the East German Embassy in Washington DC and offering to sell classified information he obtained while working as a civilian engineer at the Naval Electronic Systems Engineering Center in South Carolina.  The operation ultimately lead to the 1983 arrest of Alfred Zehe.
