Naval officer; born in
Provence, France; was one of the
chief officers of the
Marquis de Ternay, commander of the French squadron sent to aid the
Americans in 1781.
He was designated to represent the navy in the conference between
Washington and
Rochambeau in Wetherfield, Conn., May 23, 1781, but was unable to be present on account of the sudden appearance of the British squadron off
Block Island.
In September following he effected a junction with the squadron of
De Grasse in
Chesapeake Bay, and the enlarged French fleet prevented the British fleet from going to the rescue of Lord Cornwallis, and so made certain the surrender of the
British at
Yorktown.
He died about 1800.
