Benedict Arnold (June 14, 1801) was a general during the American Revolutionary War who originally fought for the American Continental Army but defected to the British Army. While a general on the American side, he obtained command of the fortifications at West Point, New York (future site of the U.S. Military Academy after 1802), overlooking the cliffs at the Hudson River (upriver from British- occupied New York City), and planned to surrender it to the British forces. After the plan was exposed in September 1780, he was commissioned into the British Army as a brigadier general.
