"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." - (en.wikipedia.org 31.01.2020)
