HMS Achilles was a 60-gun fourth-rate ship of the line built for the Royal Navy, launched on 6 February 1757 at Harwich by Barnard and Turner. Constructed according to the draught specified by the 1745 Establishment, amended in 1750, Achilles was part of the Dunkirk-class, along with HMS Dunkirk and HMS America. The vessel measured approximately 60 guns, characteristic of fourth-rate ships of the line, designed to serve both in fleet actions and as a versatile combatant during the mid-18th century. Throughout her service, HMS Achilles participated in notable engagements. In April 1758, she was involved in the pursuit of the French 64-gun ship Raisonnable, engaging her alongside HMS Dorsetshire, which first engaged Raisonnable. After a fierce encounter resulting in 35 casualties, Raisonnable was captured and subsequently purchased by the Royal Navy. The ship also distinguished itself in April 1759 when, under Lieutenant Samuel Barrington, Achilles captured the French coastguard vessel St Florentine after a two-hour battle, suffering 2 killed and 23 wounded. In July 1759, Achilles served as the flagship of Rear-Admiral George Rodney during a mission to Le Havre, where the British fleet aimed to destroy French invasion preparations. The operation involved a fleet of four 50-gun ships, frigates, a sloop, and bomb ketches, with Achilles remaining at Le Havre for the remainder of the year. In 1762, Achilles played a strategic role in the Battle of Belleisle, sailing with a large force to attack the French-held island. Although the initial assault was repelled, the subsequent successful siege led to the French surrender in June 1762. Following her active service, Achilles became Portsmouth's guardship in 1763. In 1782, she was hulked—meaning she was converted into a stationary ship—before being sold in 1784 to merchants for use as a cargo vessel. Remarkably, she remained in sound condition until her final dismantling in 1791, when she was broken up for timber, marking the end of her maritime career.
