CREQUY, FRANCOIS, CHEVALIER DE, marquis de Marines (1625-1687), marshal of France, grandson of the preceding, took part as a boy in the Thirty Years' War. At the age of 26 he was made marechal de cam* and lieutenant-general before he was thirty. He won the favour of Louis XIV. by his fidelity to the court during the second Fronde. In 1667 he served on the Rhine, and in 1668 he commanded the covering army during Louis XIV.'s siege of Lille, after the surrender of which the king made him marshal. In 167o he overran the duchy of Lorraine. Shortly afterward, Turenne, his old commander, was made mar shal-general, and all the marshals were placed under his orders. Crequy went into exile rather than serve under Turenne. After the death of Turenne and the retirement of Conde, he became the most important general officer in the army. He was defeated at Conzer Briicke on the Moselle (1675) by the duke of Lorraine and was taken prisoner. After his release he took the field again in 1676 in Lorraine, and showed himself again a cool, daring and success ful commander. (See DUTCH WARS.) The marshal had two sons. The elder, Francois Joseph, marquis de Crequy (1662-1702), already held the grade of lieutenant general when he was killed at Luzzara ; and Nicolas Charles, sire de Crequy, was killed before Tournai in 1696 at the age of twenty-seven.
