Which 1781 battle was the last major land battle of the American Revolutionary War?

The Siege of Yorktown was the last major land battle of the American Revolutionary War.

American and French forces trapped the British army commanded by Lord Cornwallis at Yorktown, Virginia, in 1781. General George Washington led the American army, while French troops and the French fleet played essential roles in surrounding the British position.

Cornwallis surrendered on October 19, 1781. The defeat did not instantly end the war, but it convinced the British government that continuing large-scale operations in North America was too costly. Peace negotiations followed, leading to the Treaty of Paris in 1783.

Yorktown is sometimes called a battle even though the campaign was primarily a siege lasting several weeks. Earlier engagements, including Saratoga and Trenton, were crucial turning points, but Yorktown produced the decisive surrender that brought major combat to a close.
