In 1782 a captured French admiral stepped onto the beach at Southsea, England, to cheering crowds, and King George III later handed back his surrendered sword. This deep dive tells the story of Francois Joseph Paul de Grasse, who began as a 12-year-old page to the Knights Hospitaller fighting on oar-powered galleys, served in India, and helped rebuild the French Navy after the Seven Years’ War.

Answering an appeal from Washington and Rochambeau, de Grasse sailed from Saint-Domingue with 3,000 troops and defeated the British at the Battle of the Chesapeake, trapping Cornwallis at Yorktown. Months later he was captured at the Battle of the Saintes, scapegoated in France after a court martial, and died in disgrace in 1788. His family legacy spans aristocratic children fleeing the Haitian Revolution and descendants of his adopted son George, including John de Grasse, the first African American to graduate from a U.S. medical school and a Union Army surgeon.
