John André

Major John André (May 2, 1750 – October 2, 1780) was a British Army officer who served as the head of Britain's intelligence operations during the American War for Independence. In September 1780, he negotiated with Continental Army officer and turncoat Benedict Arnold, who secretly offered to turn over control of the American fort at West Point, New York to the British. Due to a series of mishaps and unforeseen events, André was forced to return to British lines from a meeting with Arnold through American-controlled territory while wearing civilian clothes.

André was captured by three Americans and was quickly identified and imprisoned; he was subsequently convicted of espionage by the Continental Army and executed by hanging on George Washington's orders. His execution led to an outburst of anti-Americanism in Great Britain, and American painter John Trumbull was imprisoned as a result. André is typically remembered positively by historians, and several prominent leaders of the Patriot cause, including Alexander Hamilton and the Marquis de Lafayette, disagreed with the American decision to execute him.
