HMS Argonaut was a 64-gun third-rate ship of the line in the Royal Navy, launched in 1779. Originally built as the French vessel Jason, she was captured by the British in 1782 during the ongoing conflicts of the American Revolution and the French Revolutionary Wars, and subsequently commissioned into Royal Navy service under the name HMS Argonaut. Constructed as a ship of the line, she featured a robust armament of 64 guns, typical of third-rate vessels designed for fleet battles. Her early service included participation in significant naval expeditions, notably serving as part of the expedition under Admiral Ternay in 1780, which supported American revolutionary forces. During this campaign, she was part of a fleet that departed Brest with transports and troops destined for North America, arriving at Boston in June 1780. In her service history, HMS Argonaut is notable for her engagement on 8 January 1795, when under Captain Alexander John Ball, she captured the French Republican warship Esperance. This vessel was armed with 22 guns and had a crew of 130 men. The capture led to a diplomatic dispute, with the French ambassador protesting to the United States over the vessel's entry into Lynnhaven Bay, which the French claimed was a violation of treaty obligations. The matter was ultimately resolved diplomatically, with Argonaut paroling her prisoners and rearming the captured Esperance for further patrols. HMS Argonaut continued active service until 1797, after which she was repurposed for harbor service. In 1804, she was converted into a hospital ship and permanently moored off Chatham Dockyard. Her role as a hospital ship lasted for several decades until she was decommissioned in 1828. The vessel was broken up in 1831, marking the end of her maritime career. Throughout her service, HMS Argonaut played a role in key naval operations of her era, illustrating the versatility and durability of third-rate ships of the line in both combat and auxiliary roles within the Royal Navy.
