In the decisive battle of the American Revolution, Cornwallis surrendered his army to Washington on October 19, 1781 at Yorktown.
The Battle of Yorktown occurred during the months of September and October 1781, at Yorktown, Virginia. American and French ground forces under the commands of General George Washington and General Jean Comte de Rochambeau, in concert with French naval forces under the command of Admiral François-Joseph, Comte de Grasse, surrounded and entrapped the British army commanded by Lieutenant General Charles Cornwallis. Following a siege and bombardment lasting about 20 days, Cornwallis surrendered his army to Washington on October 19, 1781. Although sporadic and bitter fighting continued in the South for several months, the victory at Yorktown was the last major engagement of the American Revolution and effectively ended the conflict in the Americans’ favor.
