In 1667, d'Artagnan was promoted to captain-lieutenant of the Musketeers, the effective commander as the nominal captain was the king. As befitted his rank and position, he could be identified by his striking burgundy, white, and black livery—the colours of the commanding officer of the Musketeers. Another of d'Artagnan's assignments was the governorship of Lille, which was won in battle by France in 1667. D'Artagnan was an unpopular governor and longed to return to battle. He found his chance when Louis XIV went to war with the Dutch Republic in the Franco-Dutch War. After being recalled to service, d'Artagnan was subsequently killed in battle on 25 June 1673, when a musket ball tore into his throat at the Siege of Maastricht.
