Which 1781 battle is remembered as the last major land engagement linked to America250?

The Siege of Yorktown is remembered as the last major land engagement linked to America250.

The siege took place in Virginia in 1781, when American forces under George Washington and French forces under the Comte de Rochambeau trapped the British army commanded by Lord Cornwallis. French naval power helped prevent British relief by sea, while allied artillery and siege operations steadily tightened the position.

Cornwallis surrendered on October 19, 1781. The victory did not legally end the Revolutionary War, but it made continued British military operations in North America increasingly difficult and encouraged peace negotiations. The Treaty of Paris, signed in 1783, formally recognized American independence.

Yorktown is sometimes called the Battle of Yorktown or the surrender at Yorktown. It should not be confused with Saratoga, the major American victory of 1777 that helped secure French support, or with the later 1783 peace settlement. Its importance lies in its military and diplomatic consequences.
