The Mont Blanc was a 74-gun ship of the line belonging to the Téméraire class, built for the French Navy during the 1790s. Originally constructed at Rochefort in 1791, she was initially named Pyrrhus before being renamed Mont Blanc in 1793. She underwent several name changes during her career, reflecting the tumultuous political climate of the French Revolution; she was also called Trente-et-un Mai in 1794 and Républicain in 1795 before reverting to Mont Blanc in 1796. Designed as a formidable warship, the Mont Blanc featured the typical armament of a 74-gun ship of her class, which was considered a balanced combination of firepower and maneuverability. Throughout her service, she participated in numerous significant naval engagements, including the last actions of the Glorious First of June, the Croisière du Grand Hiver, the Battle of Hyères Islands, and Bruix's expedition of 1799. She also took part in the Saint-Domingue expedition in 1802. A notable moment in her history was her presence at the Battle of Trafalgar on 21 October 1805, where she served in the vanguard under Rear-Admiral Lepelley, commanded by Captain Ganteaume. However, her division was cut off from the main battle and saw little action. Following the defeat of the French fleet, Mont Blanc was captured during the subsequent Battle of Cape Ortegal on 4 November 1805, when a British squadron under Sir Richard Strachan defeated and took control of the remnants of the French fleet. After her capture, the Royal Navy commissioned her as HMS Mont Blanc. Her subsequent service was limited; by 1811, she was repurposed as a gunpowder hulk, a static storage vessel, and she remained in this role until she was sold in 1819. Her career reflects the shifting alliances and naval conflicts of the late 18th and early 19th centuries, making her a significant vessel in both French and British maritime history.
