In 1780, a fleet with 6,000 troops commanded by Lieutenant General Jean-Baptiste, comte de Rochambeau landed at Newport, Rhode Island; shortly afterward, the British blockaded the fleet. In early 1781, Washington and de Rochambeau planned an attack against the British in the Chesapeake Bay area to coordinate with the arrival of a large fleet under Vice Admiral François, comte de Grasse. Washington and de Rochambeau marched to Virginia after successfully deceiving the British that an attack was planned in New York, and de Grasse began landing forces near Yorktown, Virginia. On September 5, 1781 de Grasse and the British met in the Battle of the Virginia Capes, which ended with the French fleet in control of Chesapeake Bay. Protected from the sea by the French fleet, American and French forces surrounded, besieged, and forced the surrender of the British forces under Lord Corwallis, effectively winning the war and leading to peace two years later.
