On his way down the Channel to join the Duke, Duquesne met an English squadron, which summoned him to lower his flag, a token of submission at that time imposed upon all foreigners by the English, if within Ushant or even Finisterre. To this demand Duquesne returned a haughty refusal, whereupon a very close and murderous engagement took place, which resulted in the English, although quite equal in guns to the French, being put to flight. On arriving off the Gironde a Spanish squadron, operating in connection with the insurgents, attempted to bar his progress; but he drove them off, and succeeded in joining the Duke, and greatly assisted in the reduction of Bordeaux and all Guienne. In recognition of his services Anne of Austria bestowed upon Duquesne a chateau and estate in Brittany, with a promise of reimbursement for his expenses in fitting out his squadron. The peace of 1659 relegated Duquesne to civil life; but Colbert, during this cessation of arms, had the wisdom to imitate Richelieu in fostering and rebuilding the navy of France, so that, when war broke out between France and Holland, in 1672, the former was able at once to send to sea a formidable fleet During this year Duquesne held a high command in the great naval battles in the North Sea; particularly those off Southwood, where Vice Admiral d’Estrées was opposed to the Dutch Admiral Benkaërt; as well as the two battles where the combined French and English fleets, under Prince Rupert, Admiral Spragge, and d’Estrées, fought the Hollanders under Ruyter, Cornelis, Tromp and Benkaërt. England suddenly made peace with Holland, but France continued the war, with the alliance of Spain, Germany, and the two Sicilies; and it is at this point that we take up Duquesne’s battles with the Dutch fleet. When he sailed from Toulon, in January, 1675, he had on board the Duke de Vivonne, General of the Galleys of France, who had been named Viceroy of Sicily. He had in charge a convoy, also, with a great store of wheat and other provisions for Messina. On February 11th, in sight of the Sicilian coast, Duquesne and Vivonne were attacked by a Spanish fleet of twenty men-of-war and seventeen galleys, commanded by Don Melchoir de la Cueva. Duquesne sustained the attack of this large force with such vigor and determination that he gave time for the Chevalier de Valbelle to arrive from Messina with a considerable reinforcement, when, in his turn taking the offensive, he drove off the Spanish fleet, pursued it until it took refuge in Naples, and then triumphantly entered Messina with his convoy. He soon after, in concert with Vivonne, captured the town of Agosta; after which Duquesne was sent back to France, with the greater part of the fleet, to bring back to Sicily munitions of war and reinforcements, then much needed at Messina.
