Benedict Arnold was an American-born military officer who served during the American Revolutionary War. He fought with distinction for the American Continental Army and rose to the rank of major general before defecting to the British 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 to British forces, but the plot was discovered in September 1780, whereupon he fled to the British lines. In the later part of the war, 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, and his name became synonymous with treason and betrayal in the United States.

West Point is the oldest continuously occupied military post in the United States. Located on the Hudson River in New York, General George Washington stationed his headquarters in West Point in the summer and fall of 1779 during the American Revolutionary War, and later called it "the most important Post in America" in 1781 following the war's end. West Point also was the site of General Benedict Arnold's infamous and failed attempt at treason during the Revolutionary War.
