paragraph_text: West Point espionage
  
  Washington became America's first spymaster by designing an espionage system against the British. In 1778, Major Benjamin Tallmadge formed the Culper Ring at Washington's direction to covertly collect information about the British in New York. Washington had disregarded incidents of disloyalty by Benedict Arnold, who had distinguished himself in many campaigns, including his invasion of Quebec and the Battle of Saratoga.
  
  In 1780, Arnold began supplying British spymaster John André with sensitive information intended to compromise Washington and capture West Point, a key American defensive position on the Hudson River. Historians Nathaniel Philbrick and Ron Chernow noted possible reasons for Arnold's defection to be his anger at losing promotions to junior officers, or repeated slights from Congress. He was also deeply in debt, profiteering from the war, and disappointed by Washington's lack of support during his eventual court-martial.
  
  After repeated requests, Washington agreed to give Arnold command of West Point in August. On September 21, Arnold met André and gave him plans to take over the garrison. While returning to British lines, André was captured by militia who discovered the plans; upon hearing the news of André's capture on September 24, while waiting to greet and have breakfast with Washington, Arnold immediately fled to HMS Vulture, the ship that had brought André to West Point, and escaped to New York.
  
  Upon being told about Arnold's treason, Washington recalled the commanders positioned under Arnold at key points around the fort to prevent any complicity. He assumed personal command at West Point and reorganized its defenses. André's trial for espionage ended in a death sentence, and Washington offered to return him to the British in exchange for Arnold, but Clinton refused. André was hanged on October 2, 1780, despite his request for a firing squad, to deter other spies.
