In recognition of his brilliant achievement, Louis XV conferred on him the Château de Chambord for life, and in April 1746, he was naturalised as a French subject. Until the end of the war, he continued to command in the Netherlands, always with success. Besides Fontenoy he added Rocoux (1746) and Lawfeldt or Val (1747) to the list of French victories. He led the French force which captured Brussels and it was under his orders that Marshal Löwendahl captured Bergen op Zoom. He himself won the last success of the war in capturing Maastricht in 1748. In 1747 the title once held by Turenne and Villars, "Marshal General of the King's camps and armies", was revived for him. But on 20 November 1750 he died at the Château de Chambord "of a putrid fever".
