Benedict Arnold was an American military officer who served during the Revolutionary War. He fought with distinction for the American Continental Army and rose to the rank of major general before defecting to the British side of the conflict in 1780. General George Washington had given him his fullest trust and had placed him in command of West Point in New York. Arnold was planning to surrender the fort there to British forces, but the plot was discovered in September 1780, whereupon he fled to the British lines. In the later part of the conflict, Arnold was commissioned as a brigadier general in the British Army, and placed in command of the American Legion. He led the British army in battle against the soldiers whom he had once commanded, after which his name became synonymous with treason and betrayal.
