HMS Alert was a 10-gun cutter launched at Dover in 1777, quickly converted to a sloop in the same year to enhance its combat capabilities. Constructed as a relatively small vessel, she was armed with ten guns, which initially classified her as a cutter, but her reclassification to a sloop reflected a change in her operational role. During the American War of Independence, HMS Alert participated in notable engagements in the English Channel. On September 19, 1777, she engaged the American 16-gun brigantine Lexington. The battle lasted approximately two hours, during which Lexington managed to damage Alert’s rigging, forcing a temporary withdrawal. However, Alert’s crew swiftly repaired the damage, and the vessel resumed pursuit. Eventually, Lexington, depleted of ammunition and unable to reply effectively, surrendered after a subsequent 90-minute bombardment. The engagement resulted in American casualties of seven killed and eleven wounded, while Alert sustained two killed and three wounded. In another notable action on June 17, 1778, HMS Alert engaged the French 10-gun lugger Coureur. After about 90 minutes of combat, Alert succeeded in forcing the French vessel to strike her colors, demonstrating her effectiveness in close-quarters naval combat. However, her service was short-lived. On July 17, 1778, HMS Alert was captured in the English Channel by the French frigate Junon. French records indicate that she was renamed Alerte and served as a cutter with fourteen 4-pounder guns. She was valued at Lt 32,289 in prize money. Unfortunately, her service came to an end in December 1779 when she foundered off the coast of America. HMS Alert’s brief yet active career highlights her role during a turbulent period of naval warfare, marked by active engagements and her ultimate capture, reflecting the intense maritime conflicts of the late 18th century.
