PIZARRO, Jose Alfonso, Marquis of Villar, Spanish naval officer, born in Murcia in 1689; died in Madrid in 1762. He entered, in his youth, the naval service of the knights of Malta, and afterward served in the Spanish navy, attaining the rank of rear-admiral. When the government heard of the expedition of the English admiral, George Anson, to the Pacific, a fleet of two ships of the line and four frigates, with a regiment of infantry for Chili, was despatched under Pizarro's command in October, 1740, and arrived, 5 January, 1741, in the river Plate. Hearing that Anson was refitting in Santa Catharina for entering the Pacific by the Strait of Lemaire, Pizarro sailed at once to intercept him, but lost one ship and one frigate in a storm, was obliged to put back for repairs, and on the second attempt, with two vessels, was again dismasted, and returned to Montevideo. Thence he despatched the frigate "Esperanza" to the Pacific, and passed across the Andes to Peru, where for some time he exercised the functions of naval commander-in-chief. After the peace with England, Pizarro left the frigate on the Pacific station and returned overland to Montevideo, where he found his flag-ship, the " Asia," refitted, and sailed in her for Europe in November, 1745. Part of the crew consisted of Indians from the pampas, who one night rose on the Spaniards, and, after killing the watch on deck, had gained possession of the vessel, when Pizarro succeeded in killing the ringleader, and in the confusion drove the mutineers into the sea. On his arrival at Cadiz in January, 1746, he was promoted vice-admiral, and in 1749 was appointed viceroy of New Granada; but he resigned in 1753 and returned to Spain.
