John Andre was a British officer hanged as a spy during the American Revolutionary war. At the age of 20 he joined the British Army and moved to North America to join the occupying forces.
He was a great favourite in society, both in Philadelphia and New York during their occupation by the British Army.
During his nearly nine months in Philadelphia, André occupied Benjamin Franklin's house, where it is said he took items from Franklin's home when the British left Philadelphia.
In 1779, he became adjutant-general of the British Army with the rank of Major. In April, he was placed in charge of the British Secret Intelligence. By the next year (1780) he had begun to plot with American General Benedict Arnold, who commanded West Point, and had agreed to surrender it to the British for £20,000 — a move that would enable the British to cut New England off from the rest of the rebellious colonies.
Using common clothes and a false passport, Andre travelled toward New York with documents supplied by Arnold. He was stopped by three men at gunpoint.
During the following conversation in which both parties were confused over the allegiance of the others, Andre admitted he was British. The three men searched him and found the papers he was hiding.
He was put on trial before a board of senior officers. On September 29, 1780, the board found Andre guilty of being behind American lines “under a feigned name and in a disguised habit”.
He was hanged as a spy at Tappan on October 2, 1780.
