The César was a mercantile brig launched in 1802, likely built as a corvette-senault with a snow rig, measuring approximately 88 feet in length and 23 feet in beam. She was initially a civilian vessel, but the French Ministry of Marine authorized her purchase from citizen Dupuch on August 29, 1803. After her acquisition, she was armed with 18 guns and commanded by Lieutenant de Vaisseau Louis François Hector Fourré, with a crew of 86 men. During her service with the French Navy, César participated in notable naval operations, including a cutting-out expedition on July 15, 1806, off the entrance to the Garonne River. British boats from the squadron under Lord St. Vincent attempted to capture her and a French convoy. Although César was successfully taken during this action—despite resistance from the French convoy—most of the attacking boats were heavily damaged or swamped, leading to the capture of César and the loss of several British men. The operation was significant enough to earn the participants the Naval General Service Medal with the clasp "16 July Boat Service 1806" in later years. The Royal Navy seized César in July 1806 following her capture, and she was taken into British service as HMS Cesar. She was described as "fit for His Majesty's Service," with her copper sheathing still intact. However, her service with the Royal Navy was short-lived; she was wrecked near the Gironde in early 1807, resulting in only 45 survivors from the disaster. César’s brief but active career highlights her role in early 19th-century naval warfare, particularly her participation in daring cutting-out operations and her transition from a French civilian vessel to a British warship before her tragic loss.
