Arnold Betrays West Point: Symbol of Treachery Born

Benedict Arnold, once one of George Washington's most trusted generals, negotiated the sale of West Point's defensive plans to the British for 20,000 pounds while serving as the fortress's commander in September 1780. The plot was discovered when American militiamen captured British Major John Andre carrying Arnold's documents in his stockings on September 23. Arnold learned of Andre's capture just in time to flee down the Hudson River aboard the British sloop HMS Vulture. Washington arrived at West Point hours later to find both Arnold and the fortress's defense plans gone. Andre was hanged as a spy. Arnold received his payment and a British commission but was distrusted by both sides for the rest of his life. His name became the American synonym for traitor.
