HMS Sans Pareil was an 80-gun third rate ship of the line of the Royal Navy, originally built as the French ship Sans Pareil at Brest. She was a Tonnant-class vessel designed by Groignard and launched on 8 June 1793. Her construction reflected the typical robust design of ships of her class, intended for line-of-battle engagements. However, her service with the French navy was brief; she entered Atlantic operations in May 1794 under Captain Courand, serving as the flagship of Rear-Admiral Joseph-Marie Nielly during an operation to escort a French corn convoy from North America. During her initial French service, Sans Pareil participated in actions including the capture of HMS Castor during a confrontation with a British squadron. She also captured several British merchant vessels, such as Gordon, Irton, Edward, and Active. Her engagement in the Atlantic was marked by her involvement in the events leading up to the Battle of the Glorious First of June, 1794, where she formed part of the French rear. At that battle, she was heavily damaged; HMS Royal George broke her line ahead of Sans Pareil, damaging her fore and mizzen masts, and HMS Glory further shot away her main mast. Disabled, Sans Pareil drifted until captured by HMS Majestic. The battle resulted in significant casualties, with estimates of up to 260 killed and 120 wounded. After her capture, Sans Pareil was commissioned into the Royal Navy and served as a flagship, initially commanded by Captain Lord Hugh Seymour. She participated in subsequent fleet actions, including the Battle of Groix in June 1795, where she engaged French ships Formidable and Peuple. Her operational tactics included flying the French ensign to lure privateers during her service off the French coast. She captured several vessels during her career, notably the Spanish trader Guachapin in 1800 and two French privateer schooners, Pensee and Sapajon, in 1801. Following her active service, she was placed in reserve and later converted into a prison hulk after an extensive refurbishment costing £35,000. By 1807, she served as a prison for French prisoners-of-war, and eventually as a sheer hulk from 1810. She remained in service in this capacity until she was broken up in October 1842. Throughout her long career, Sans Pareil exemplified the transition from active line-of-battle ship to a stationary prison hulk, marking her as a vessel of notable maritime history during the Napoleonic era.
