Anne Hilarion De Cotentin Tourville, count de, a French admiral, born Nov. 24, 1642, died in Paris, May 28, 1701. After brilliant exploits against the pirates of N. Africa, which won for him from Venice the title of protector of commerce, Louis XIV. appointed him in 1667 naval commander. In 1676 he decided the victory of Agosta, and in 1677, off Palermo, he nearly destroyed the allied squadrons of Spain and Holland. After various other achievements he became in 1689 vice admiral of the Levant. In 1690, operating against the English and Dutch off Beachy Head, he pursued the former to the mouth of the Thames, where he destroyed many of their ships and transports. In 1691, as commander of the ocean fleet, he enabled the French troops to reach Ireland in aid of James II. In 1692, by positive order from Louis XIV., at the head of 44 ships, he engaged off the fort of La Hogue, on the E. coast of Cotentin, the English admiral Russell, whose forces were nearly double, and, after 12 hours of determined resistance, was defeated, but escaped to port with the remains of his fleet.

In 1693 he was appointed marshal, and in the same year he captured 27 Dutch and English ships off Cape St. Vincent and destroyed 59. He retired after the peace of Ryswick in 1697.
