Overview
From 1927–34, nine submarines of the Diane class were built in Le Havre and Le Tréport. All were named after figures from Greek mythology and were intended for service in the Mediterranean. Diane, the lead boat of this class, was built in Le Havre and served as part of the 14th Submarine Division. At the start of World War II, the 14th Division—like the entire 2nd Submarine Squadron—was based in Algeria. In 1939–40, Diane carried out patrols in the Mediterranean and Atlantic. After France’s capitulation, the submarine became part of the Vichy fleet. In early July 1940, when Britain attacked the French base at Mers-el-Kébir, Diane unsuccessfully attempted to engage British warships. From October 1941 to November 1942, the submarine remained out of service. Diane was scuttled on November 9, 1942, to prevent her capture by the Allies who had landed in North Africa.
