(Abraham du), marquis of Quesne, admiral of the naval forces of France, and one of the greatest men of the last age, was born in Normandy in 1610. He contributed to the defeating of the naval power of Spain before Gattari; was dangerously wounded before Barcelona in 1642, and on other occasions; he went into the service of the Swedes, and became vice-admiral; gave the Danes an entire defeat, killed their admiral, and took his ship. He was recalled into France in 1647, and commanded the squadron sent to Naples. The sea-affairs of France being much fallen, he fitted out divers ships for the relief of the royal army that blocked up Bordeaux; which was the principal cause of the surrender of the town. He was very fortunate in the last wars of Sicily, where he beat the Dutch thrice, and De Ruyter was killed. He also obliged the Algerines to sue for peace from France in a very humble manner. In short, Asia, Africa, and Europe, felt the effects of his valour. He was a Protestant; yet the king bestowed on him the land of Bouchet, and to immortalize his memory gave it the name of that great man. He died in 1688.
