HMS Britannia (1762)

HMS Britannia (1762) was a 100-gun first-rate ship of the line of the Royal Navy. Launched late in the Seven Years' War, she served as a flagship for several prominent admirals during the American Revolutionary War and the French Revolutionary Wars. The ship is best remembered for her role as the flagship of Admiral Charles Thompson at the Battle of Cape St. Vincent and later as the flagship of Admiral of the Fleet William Cornwallis. After a long career, she ended her service as a receiving ship and prison ship at Portsmouth before being broken up.

Construction and design

Ordered in 1751 to the dimensions of the 1745 Establishment, HMS Britannia was built at Portsmouth Dockyard under the supervision of Master Shipwright Thomas Bucknall. Her construction was protracted, spanning over a decade due to periods of inactivity, and she was finally launched in October 1762, just as the Seven Years' War was concluding. As a standard 100-gun first-rate, her armament was spread across three gundecks, carrying a powerful battery of 42-pounder, 24-pounder, and 12-pounder guns. Her design was typical of the large, three-decked man-of-war that formed the backbone of the British fleet during the age of sail, intended primarily for service as a flagship in the line of battle.

Service history

Initially placed in ordinary after launch, Britannia was not commissioned for active service until September 1778, following French entry into the American Revolutionary War. She served as the flagship for Vice Admiral George Darby during the relief of Gibraltar in 1781 and was present at the subsequent Battle of Cape Spartel. During the French Revolutionary Wars, she was the flagship of Admiral Charles Thompson at the pivotal Battle of Cape St. Vincent under the overall command of Admiral Sir John Jervis. Later, from 1801 to 1806, she served as the flagship of Admiral William Cornwallis, commander of the Channel Fleet, blockading the French port of Brest.

Commanding officers

Notable officers who commanded HMS Britannia include Captain John Moutray during her initial commissioning in 1778. At the Battle of Cape St. Vincent, she was commanded by Captain Thomas Foley, with Admiral Charles Thompson aboard as fleet commander. During her time as flagship of the Channel Fleet, her captain was Sir John Markham, serving under Admiral William Cornwallis. These officers were part of a cadre of experienced Royal Navy leaders who served during the conflicts of the late 18th and early 19th centuries.

Fate

By 1812, HMS Britannia was deemed unfit for frontline service. She was converted into a receiving ship at Portsmouth, providing accommodation for newly recruited sailors. In 1822, she was further downgraded to serve as a prison ship. After over six decades since her launch, the aged first-rate was finally broken up at Portsmouth in 1825. Some of her timbers were reputedly used in the construction of the Haslar Hospital and other buildings in the dockyard area.
