<Li> Spencer's Ordinary </Li> <Li> (order of battle) </Li> <P> The Siege of Yorktown, also known as the Battle of Yorktown, the Surrender at Yorktown, German Battle or the Siege of Little York, ending on October 19, 1781, at Yorktown, Virginia, was a decisive victory by a combined force of American Continental Army troops led by General George Washington and French Army troops led by the Comte de Rochambeau over a British Army commanded by British peer and Lieutenant General Charles Cornwallis . The culmination of the Yorktown campaign, the siege proved to be the last major land battle of the American Revolutionary War in the North American theater, as the surrender by Cornwallis, and the capture of both him and his army, prompted the British government to negotiate an end to the conflict . The battle boosted faltering American morale and revived French enthusiasm for the war, as well as undermining popular support for the conflict in Great Britain . </P> <P> In 1780, approximately 5,500 French soldiers landed in Rhode Island to assist their American allies in operations against British - controlled New York City . Following the arrival of dispatches from France that included the possibility of support from the French West Indies fleet of the Comte de Grasse, Washington and Rochambeau decided to ask de Grasse for assistance either in besieging New York, or in military operations against a British army operating in Virginia . On the advice of Rochambeau, de Grasse informed them of his intent to sail to the Chesapeake Bay, where Cornwallis had taken command of the army . Cornwallis, at first given confusing orders by his superior officer, Henry Clinton, was eventually ordered to build a defensible deep - water port, which he began to do in Yorktown, Virginia . Cornwallis' movements in Virginia were shadowed by a Continental Army force led by the Marquis de Lafayette . </P>
