Nathan Hale was considered the first American spy in history. Fighting for the Continental Army during the American Revolutionary war, he voluntarily undertook a dangerous mission behind enemy lines. Dressed in disguise, he was sent on an intelligence gathering mission in New York City. However, he was subsequently caught by the British and executed for espionage. His last words ring in American history, "I only regret that I have but one life to give for my country." There now stands a statue of this American hero In Langley, Virginia, at the Central Intelligence Agency's headquarters.
