Yorktown
Vaudreuil's contribution to this effort was to provide the cavalry of Duke of Lauzun, a foreign legion that was a mixed lot of Russian, Slavic, Polish and German mercenaries in the service of France. He also provided 800 men from his ship to Gloucester Point in defence of a peninsula near Yorktown. Together with the Duke of Lauzun these men fought the cavalry of Tarleton (made famous by the Mel Gibson movie The Patriot), and defeated him.
