GRASSE, FRANOIS-JOSEPH-PAUL, COUNT (COMTE) DE, MARQUIS D

born Sept. 13, 1722, Le Bar, France died Jan. 11, 1788, Paris French naval commander who engaged British forces during the U.S. War of Independence (1775-83). De Grasse took service in 1734 on the galleys of the Knights of Malta, and in 1740 he entered the French service. Shortly after France and the United States joined forces in the Revolutionary War, he was dispatched to America as commander of a squadron. In 1779-80 he fought the English off the West Indies. In 1781 he was promoted to the rank of admiral and was successful in defeating Admiral Samuel Hood and in taking Tobago. When the American commander George Washington and the French general the Count de Rochambeau determined to march to Virginia to join forces with the Marquis de Lafayette's army against the British commander Lord Cornwallis, Washington requested the cooperation of de Grasse's fleet. De Grasse therefore sailed from the West Indies to the Chesapeake River, where he was joined by a fleet under Count de Barras. A British force under Admiral Thomas Graves attempted to prevent this juncture by engaging de Grasse's fleet when it arrived at the Chesapeake Bay but was unsuccessful. French naval supremacy in the waters off Yorktown was instrumental in the success of the siege of that city. After Cornwallis' surrender, de Grasse returned to the West Indies, where he captured the island of St. Kitts in January 1782. In April, however, he was defeated by Admiral George Rodney and taken prisoner. On his return to France, he published a Mmoire justificatif and was acquitted by a court-martial in 1784.
