Marshal of France in the reign of Louis XIV.; military engineering was his great forte, and as such he "conducted 53 sieges, was present at 104 battles, erected 33 fortresses, and restored the works of 300 old ones"; he was originally in the service of Spain, and was enlisted in the French service by Cardinal Mazarin; he was a political economist as well as engineer, but his animadversions only procured for him the royal disfavour (1633-1707).
