EDWARD, a brave British admiral, was the second son of Hugh Lord Viscount Falmouth. Having early entered into the navy, he was, in 1740, captain of the Shoreham; and behaved with great intrepidity as a volunteer under Admiral Vernon, at the taking of Porto-Bello. At the siege of Carthagena, in March 1741, he had the command of a party of seamen who resolutely attacked and took a battery of fifteen twenty-four-pounders, though exposed to the fire of another fort of five guns. Lord Aubrey Beauclerc having been killed at the attack of Boca-Chica, Captain Boscawen succeeded him in the command of the Prince Frederick of seventy guns. In May 1742 he returned to England, and married Frances, daughter of William Glanville, Esq.; and the same year he was elected representative for Truro in Cornwall. In 1744 he was made captain of the Dreadnought of sixty guns; and soon after he captured the Medea, a French man of war commanded by M. Hoquart, the first ship taken in that war. In May 1747 he signalized himself under the admirals Anson and Warren, in an engagement with the French fleet off Cape Finisterre, and was wounded in the shoulder with a musket ball. Here M. Hoquart, who then commanded the Diamond of fifty-six guns, again became his prisoner; and all the French ships of war, ten in number, were taken. On the 15th of July he was made rear-admiral of the blue, and commander-in-chief of the sea and land forces employed on an expedition to the East Indies; and on the 4th of November he sailed from St Helen's, with six ships of the line, five frigates, and 2000 soldiers. On the 29th of July 1748 he arrived at St David's, and soon after laid siege to Pondicherry; but the men growing sickly, and the monsoons being expected, the siege was raised, and Mr Boscawen showed himself as much the general as the admiral in his retreat. Soon afterwards he received news of the peace, and Madras was delivered up to him by the French. In April 1750 he arrived at St Helen's in the Exeter, and found that in his absence he had been appointed rear-admiral of the white. He was the next year made one of the lords commissioners of the admiralty, and chosen an elder brother of the Trinity-house. In February 1755 he was appointed vice-admiral of the blue. On the 19th of April, sailing in order to intercept a French squadron bound to North America, he fell in with the Alcide and Leyes of sixty-four guns each, which were both taken. On this occasion M. Hoquart became his prisoner for the third time, and he returned to Spithead with his prizes and 1500 prisoners. In 1756 he was appointed vice-admiral of the white, and in 1758 admiral of the blue and commander-in-chief of the expedition to Cape Breton, when, in conjunction with General Amherst, and a body of troops from New England, the important fortress of Louisbourg and the whole island of Cape Breton were taken; services for which he afterwards received the thanks of the House of Commons. In 1759, being appointed to command in the Mediterranean, he arrived at Gibraltar, where hearing that the Toulon fleet, under M. de la Clue, had passed the Straits in order to join that at Brest, he got under sail, and on the 18th of August saw, pursued, and engaged the enemy. His ship, the Namur of ninety guns, losing her mainmast, he shifted his flag to the Newark; and, after a sharp engagement, took three large ships and burnt two, in Lagos Bay, after which he returned to Spithead with his prizes and 2000 prisoners. On the 8th December 1760 he was appointed general of the marines with a salary of £3000 per annum, and was also sworn a member of the privy council. He died in 1761.
