The French ship Tonnant was an 80-gun ship of the line constructed in Toulon between 1740 and 1744. As a formidable warship, she served as the flagship of the French Navy during significant naval engagements of the 18th century. Her armament comprised 80 cannons, making her a powerful vessel capable of engaging multiple adversaries in fleet battles. Tonnant played a prominent role as the flagship of Louis XV's fleet, serving as the admiral vessel under Marquis de l'Estenduère. She notably participated in the Second Battle of Cape Finisterre in 1747, a fierce engagement where the French sacrificed eight ships in a strategic effort to protect merchant convoys against the British fleet commanded by Admiral Hawke. During this battle, Tonnant was partly dismasted but managed to escape destruction by being towed to safety by the ship Intrépide of Vaudreuil, which crossed British lines to secure her. The vessel also took part in the Battle of Quiberon Bay in 1759, a decisive British victory that thwarted French plans to invade Britain. During this engagement, Chevalier de Bauffremont was aboard Tonnant. After the battle, she sought refuge in Rochefort. Refurbished in 1770, Tonnant saw renewed service during the American War of Independence. She participated in Admiral Estaing’s campaign in America from 1778 to 1779, engaging in key actions such as the attack on Newport in 1778 and the Battle of Grenada on July 6, 1779. Her service record highlights her as a significant player in France’s maritime efforts during this period. Ultimately, Tonnant was broken up in 1780, marking the end of her nearly four-decade-long service. Her participation in major naval battles and her status as a flagship underscore her importance in 18th-century French naval history.
