WALKER, Sir Hovenden, British officer, born in Somersetshire, England, about 1660; died in Dublin, Ireland, in January, 1726. He entered the navy in his youth, became a captain in 1692, and rear-admiral of the white in 1710, and in 1711 was knighted by Queen Anne. In the last-named year he commanded the fleet that sailed from Boston on 30 July, for the conquest of Canada. Delays, a badly organized method of supplies, and the incompetency of its leaders made the expedition a failure. Half of Walker's ships were wrecked in a storm on Isle aux (Eufs, on St. Lawrence river, and Walker returned to England, where he charged that his troubles had been due to want of proper co-operation on the part of the New Englanders. These charges were answered by Jeremiah Dummer in a " Letter to a Noble Lord concerning the Late Expedition to Canada" (London, 1712). In 1715 Walker's ship, the." Edgar," of seventy-four guns, blew up at Spithead, and nearly all the crew perished. He was blamed for negligence in the matter, and, his Canadian experience being still fresh in the public mind, he was dismissed the service. He then settled on a plantation in South Carolina. Admiral Walker published in his vindication "A Journal or Full Account of the Late Expedition to Canada" (London, 1720).
