American Revolutionary War: The siege of Yorktown comes to an end.

The American Revolutionary War, also known as the Revolutionary War or American War of Independence, was the armed conflict that comprised the final eight years of the broader American Revolution, in which American Patriot forces organized as the Continental Army and commanded by George Washington defeated the British Army. The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. The war's outcome seemed uncertain for most of the war. But Washington and the Continental Army's decisive victory in the Siege of Yorktown in 1781 led King George III and the Kingdom of Great Britain to negotiate an end to the war in the Treaty of Paris two years later, in 1783, in which the British monarchy acknowledged the independence of the Thirteen Colonies, leading to the establishment of the United States as an independent and sovereign nation.

The siege of Yorktown, also known as the Battle of Yorktown and the surrender at Yorktown, was the final battle of the American Revolutionary War. It was won decisively by the Continental Army, led by George Washington, with support from the Marquis de Lafayette and French Army troops, led by the Comte de Rochambeau, and a French Navy force commanded by the Comte de Grasse over the British Army commanded by British Lieutenant General Charles Cornwallis. The siege began on September 28, 1781, and ended on October 19, 1781, at exactly 10:30 am in Yorktown, Virginia.
