The Yorktown campaign, also known as the Virginia campaign, was a series of military maneuvers and battles during the American Revolutionary War that culminated in the siege of Yorktown in October 1781. The result of the campaign was the surrender of the British Army force of General Charles Earl Cornwallis, an event that led directly to the beginning of serious peace negotiations and the eventual end of the war. The campaign was marked by disagreements, indecision, and miscommunication on the part of British leaders, and by a remarkable set of cooperative decisions, at times in violation of orders, by the French and Americans.
