John Andre entered the British army in 1771 and joined the 7th Regiment of Foot in Canada in 1774. Captured when American forces took Fort Saint-Jean in 1775, he spent time as a prisoner before exchange. Alongside military work, he drew, wrote and helped organize the elaborate Mischianza entertainment in occupied Philadelphia in 1778. In 1779 Andre became a major and Clinton's adjutant general, also directing British intelligence operations in America. In September 1780 Andre sailed upriver aboard HMS Vulture and went ashore to meet Arnold and obtain details of the defenses. His captors discovered military papers concealed in his stockings, exposing the plan and allowing Arnold to escape to British protection. A board of American generals judged Andre a spy. His remains were transferred to Westminster Abbey in 1821. In September 1780, André negotiated with Continental Army general Benedict Arnold, who secretly offered to turn over control of the American fort at West Point, New York, to the British. Clinton personally detested Arnold, but declined to hand him over to the Americans. André was hanged by the Continental Army as a spy in Tappan on October 2, 1780. According to witnesses, he placed the noose around his own neck and tightened it. The day before his hanging, André drew a likeness of himself with pen and ink, which is now owned by Yale College. A religious poem was found in his pocket after his execution, written two days beforehand. Lafayette was reported to have wept at the execution of André.
