On what date did the Siege of Yorktown's British surrender ceremony occur?

The Siege of Yorktown's British surrender ceremony occurred on October 19, 1781.

American and French forces surrounded the British army commanded by Lieutenant General Charles Cornwallis at Yorktown, Virginia. George Washington led the Continental Army, while French land forces and the French navy played crucial supporting roles.

A French naval victory in the Chesapeake helped prevent British relief by sea. Allied artillery then weakened the defenses, and American and French troops captured key redoubts on October 14.

Cornwallis did not attend the ceremony, claiming illness. His deputy, Brigadier General Charles O'Hara, formally offered the sword on his behalf. Yorktown was the last major land engagement of the Revolutionary War, although fighting at sea continued until peace negotiations produced the Treaty of Paris.
