Before we detail his operations there, it may be of interest to give some sketch of this very remarkable man. Abraham, Marquis Duquesne, one of the greatest seamen France ever produced, was born in Dieppe, an important seaport in the north of France. He entered the navy early, and soon rose to the command of a ship, in which he joined in the recapture of some of the French islands from the Spaniards, for which service he was reported most favorably to the great Richelieu. During these operations he learned of the death of his father, in action with the Spaniards, and Duquesne seems ever after to have entertained the greatest dislike for this nation, causing them to feel the effects of his resentment on numberless occasions. In 1638 he, under circumstances of great difficulty and danger, rescued from under the guns of St. Sebastian several French vessels which had been stranded there. The same year, at the battle of Gattari, Duquesne decided the victory by blowing up the Spanish admiral’s flag-ship, by means of a fire-vessel. The next year he served on the Biscayan coast, and, at Santona, was dangerously wounded in the jaw by a bullet, while boarding a Spanish galleon. During 1641 he served against Spain in the Mediterranean, was constantly engaged, and again wounded. In succeeding years he was actively employed, at Cape de Gatte, and at Carthagena, and was again wounded. Already a veteran, Duquesne was obliged, by the neglect into which the French navy fell after Richelieu’s death, to take service under the Swedes, then engaged in a naval war with Denmark. Queen Christina, who knew his merit, received him cordially, and made him a vice-admiral. In this capacity he was engaged in the naval battle of 1644, under Fleming and Torstensen, against the old king, Christian IV, of Denmark. He also served in other naval battles, in the north, under Admiral Wrangel. Peace being concluded between Denmark and Sweden, Duquesne left the service of the latter State, and returned to his own country; and, in 1645, was again actively employed against Spain, and was again wounded. In 1647, being then a _capitaine de vaisseau_, he was sent to Sweden to purchase four vessels of the line for the French navy. After this he had command of Dunkirk, in French Flanders, for five years. In 1653 occurred the naval operations of the Duke de Vendome, about the mouth of the Gironde, in consequence of the civil war of the Fronde. The French navy had at this time so decreased that the Duke, in summoning Duquesne from the North Sea to his assistance, was obliged to ask the latter to man and equip some of the vessels at his own expense.
