Background and detail

Background. Arnold, a major general who had fought with distinction for the Continental Army, obtained command of West Point on August 3, 1780. As the summer of 1780 ended, he had at last taken command and was positioned to facilitate a British takeover of the forts. He had already been providing the British with troop locations and strengths since 1779.

The Plot with André. In September 1780, Arnold negotiated with Major John André, the British Army officer who headed Britain's intelligence operations, secretly offering to turn over control of the American fort at West Point, New York, to the British. Arnold planned to surrender the fort to British forces.

Exposure and Flight. Due to a series of mishaps, André was forced to return to British lines from a meeting with Arnold through American-controlled territory while wearing civilian clothes. American militiamen captured him carrying papers revealing the plot, exposing Arnold's plan to surrender the fort. Arnold fled to the British lines.
