Brigadier General Benedict Arnold was an American-born senior officer of the British Army who commanded the American Legion in the later part of the Revolutionary War. He is best known for his defection from the Continental Army to the British side of the conflict in 1780.

Arnold planned to surrender the fort to British forces, but the plot was discovered in September 1780 and he fled to the British lines. Arnold's name quickly became a byword in the United States for treason and betrayal because he led the British army in battle against the very men whom he had once commanded.

Their numbers were boosted by the addition to their fleet of two more ships, one of which was commanded by Stede Bonnet; but Hornigold retired from piracy toward the end of 1717, taking two vessels with him.
