Washington did not know whether the British might reopen hostilities after Yorktown. They still had 26,000 troops occupying New York City, Charleston, and Savannah, together with a powerful fleet. The French army and navy departed, so the Americans were on their own in 1782–83. The treasury was empty, and the unpaid soldiers were growing restive, almost to the point of mutiny or possible "coup d'état". Washington dispelled the unrest among officers of the Newburgh Conspiracy in 1783, and Congress subsequently created the promise of a five years bonus for all officers.
