HMS Unicorn was a 28-gun Unicorn-class sixth-rate frigate of the Royal Navy, built as a modification of the original draft of the French privateer Tyger. This vessel was one of the first true frigates constructed for the Royal Navy, distinguished by its unique design features, including a beakhead bow, a unicorn figurehead, two-light quarter galleries, and five pairs of quarterdeck gunports—although it was initially commissioned with 24 guns, it was completed with 28, incorporating four additional smaller weapons on the quarterdeck. Notably, HMS Unicorn was the third ship to bear this name, and it shared design similarities with HMS Lyme, its near-sister ship, though they differed in details such as bow shape, figurehead, and gunport arrangement. Commissioned in March 1749 under Captain Molyneaux Shuldham, Unicorn’s early service was based in the Mediterranean, where she served until she paid off at Deptford in June 1752. After repairs, she was recommissioned in 1753 under Captain Matthew Buckle and again sailed to the Mediterranean. Throughout her career, she saw multiple commanders, including Captain James Galbraith and Captain John Rawling. HMS Unicorn’s most notable engagement occurred on 8 January 1761, when she captured the French frigate Vestale after a two-hour battle off the Penmarks. During the fight, Unicorn’s captain, Hunt, was wounded and died from his injuries shortly afterward. The engagement resulted in five British killed and ten wounded, with the French suffering many casualties, including their captain, Boisbertelot, who lost a leg and succumbed to his wounds the following day. The captured Vestale was taken into Royal Navy service as HMS Flora. The following days saw Unicorn pursuing other French vessels, including L'Aigrette, although she was hampered by damage sustained in battle. After active service during the Seven Years’ War, HMS Unicorn paid off in late 1763 and was ultimately broken up in 1771. Her service marked an important step in the development of true frigates in the Royal Navy and demonstrated her role in significant naval actions during her active years.
