Who forced Cornwallis?

Cornwallis was forced to surrender at the Siege of Yorktown in 1781 during the American Revolutionary War. The combined forces of American troops, led by General George Washington, and French forces, commanded by General Rochambeau, effectively besieged his position. The strategic blockade by the French navy prevented Cornwallis from receiving reinforcements or supplies, ultimately leading to his capitulation. This defeat marked a significant turning point in the war, contributing to the eventual independence of the American colonies.
