Near this spot, a musket ball crashed into General Benedict Arnold's leg as he led a charge to the rear of the fortified camp, breaking the bone in his ankle and leaving him injured for life. After eight months of healing, George Washington named Arnold military governor of Philadelphia to stabilize the city after the British ended their occupation in 1778. Arnold's resentment of perceived mistreatment boiled into a rage against the United States, and he secretly sought British support and shared military intelligence. Exposed as a traitor at West Point in 1780, Arnold escaped. His very name came to mean traitor to generations of Americans, even as his role in winning the Battles of Saratoga was celebrated without naming him.
