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 battles.
