The French ship Prince Jérôme was a late ship of the line of the French Navy, originally begun in 1827 as part of the Hercule class, specifically as the Hannibal. Construction commenced during the reign of King Louis-Philippe, but the vessel was abandoned for nearly thirty years, remaining incomplete until the Second French Empire undertook its final completion. By this time, the ship had been transformed into a steam-powered ship of the line, reflecting the maritime technological transition of the period. The vessel’s specifications as built are not detailed in the source, but she was notable for her dual propulsion system—steam power combined with traditional sailing rig. Her initial service was limited, and she was considered obsolete by the time of the French Third Republic. Consequently, she was renamed Hoche and struck from the naval lists shortly thereafter. In 1872, the ship was recommissioned as a transport vessel under the name Loire, reflecting her new role. Extensive reconstruction took place between October 1872 and February 1873, transforming her into a vessel capable of transporting large numbers of convicts and deportees. Modifications included removal of her artillery and machinery, the installation of a lighter rig, and the construction of a superstructure called a teugue—an extension at the bow—and side cylinders outside the hull. The ship was fitted with prisons that could hold approximately 350 inmates, along with provisions for free passengers and crew, accommodating a total of around 800 convicts, 200 free passengers, and 400 crew members for voyages lasting up to ten months. Throughout her service, Prince Jérôme, renamed La Loire, participated in deportation missions, notably transporting convicts and deportees to New Caledonia. She made several voyages, including a notable trip in 1874 where she carried 280 convicts and 50 Algerian deportees from France to Nouméa, with stops en route and some fatalities at sea. After her active service, she ended her career as a hulk in Saigon in 1885, marking the end of her maritime significance as a symbol of 19th-century French naval and penal transport efforts.
