DE RUYTER, MICHAEL ADRIANZOON (1607 1676), Dutch naval officer, was born at Flushing on March 24, 1607. In 1636 he was entrusted by the merchants of Flushing with the command of a cruiser against the French pirates. In 164o he entered the service of the United Provinces, and, being appointed rear-admiral of a fleet fitted out to assist Portugal against Spain, specially distinguished himself at Cape St. Vincent, Nov. 3, 1641. In the following year he left the service of the United Provinces to command a merchant vessel. In 1652 a squadron of seventy vessels was despatched against the English, under the command of Admiral Tromp. De Ruyter, who accompanied the admiral in this expedition, seconded him with great skill and bravery in the three battles which were fought with the English off Plymouth, the Kentish Knock, and Dungeness. He was afterwards stationed in the Mediterranean, where he captured several Turkish vessels. In 1659 he received a commission to join the king of Denmark in his war with the Swedes. As a reward for his services, the king of Denmark ennobled him and gave him a pension. In 1661 he grounded a vessel belonging to Tunis, released forty Christian slaves, made a treaty with the Tunisians, and reduced the Algerine corsairs to submission. He recaptured English settlements on the west coast of Africa but was repulsed at Barkad and failed to recover New Amsterdam. He returned to take command of a large fleet which had been organized against England, and in May of the following year, after a long contest off the North Foreland, he compelled the English to take refuge in the Thames and burnt the "King Charles" and other warships in the Medway. On June 7, 1672, he fought a drawn battle with the combined fleets of England and France, in Southwold bay, and convoyed safely a fleet of merchantmen. In 1676 he assisted Spain against France in the Mediterranean, and, receiving a mortal wound in the battle on April 22, off Messina, died on the 29th at Syracuse. His body was carried to Amsterdam, where a magnificent monu ment to his memory was erected by command of the States General. (See also DUTCH WARS.)
