François Joseph Paul, comte de Grasse (13 September 1722 – 11 January 1788) was a career French officer who achieved the rank of admiral.
He is best known for his command of the French fleet at the Battle of the Chesapeake in 1781 in the last year of the American Revolutionary War.
It led directly to the British surrender at Yorktown and helped gain the rebels' victory.
After this action, de Grasse returned with his fleet to the Caribbean.
In 1782 British Admiral Rodney decisively defeated and captured Grasse at the Battle of the Saintes.
Grasse was widely criticised for his loss in that battle.
On his return to France in 1784, he demanded a court martial; it acquitted him of fault in his defeat.
His grown children from his marriages all emigrated to Saint-Domingue, his eldest son Auguste assigned there as a naval officer, and joined by his stepmother and sisters after the father's death.
They had lost property in the French Revolution.
He was among French officers who surrendered to the British during the Haitian Revolution.
Auguste and his four sisters went as refugees to Charleston, South Carolina, where two sisters died of yellow fever.
One married and founded a family line with her husband in New York City.
Grasse's natural, adopted Indian-French son, George de Grasse, emigrated to New York City by 1799, where he married and made his adult life.
The admiral's eldest son, known as Auguste de Grasse, returned to France after Napoleon came to power, and re-entered the military.
