JOHN BYRON, the second son of William, the fourth Lord Byron, by his third wife, was born at Newstead Abbey, November 8th, 1723, and at an early age entered as a midshipman in the British navy. He still held that rank in 1740, when the expedition to the South Sea against the Spaniards took place under the command of Commodore Anson. The Wager, Captain Cheap, to which Mr. Byron belonged, was separated from the rest of the squadron, and wrecked on a desert island to the southward of Chiloe (47° south lat.) After encountering the most dreadful sufferings from famine, a small number of the crew, including the Captain and Mr. Byron, reached the isle of Chiloe, and surrendered themselves prisoners to the Spaniards. They were afterwards removed to Chili, and detained some time at Valparaiso and St. Jago; but were at length allowed to return to England, where they arrived after an absence of more than five years. At a subsequent period, Mr. Byron published his "Narrative." The young seaman was not deterred by his misfortunes from pursuing his naval career; he returned to the service of his country, and commanded the America, in Boscawen's action off Cape Lagos, August 18, 1759. His skill and enterprising spirit afterwards occasioned his appointment to the command of an expedition fitted out to make discoveries in the South Sea.[2] He sailed from England, June 21st, 1764, and having circumnavigated the globe, returned home in May, 1766. Several islands were explored in this voyage, which were afterwards visited by Bougainville and Cooke; and experiments were also made to determine the accuracy of Harrison's time-keeper, and its consequent value as a means of ascertaining the longitude. This officer subsequently was made an admiral, and commanded in the West Indies during the American war. Admiral Byron was much beloved in the navy, more so, perhaps, than any other officer except Nelson. He died in 1798, leaving one son, John, who dying before his uncle, Lord Byron, the title of the latter descended to his only son, George Gordon, the poet.
