Of the remaining submarines, "Diamant" was scuttled at Toulon on 27 November 1942; "Nautilus", "Saphir" and "Turquoise" were demobilized in Bizerte between 1941 and 1942. After the occupation of Tunis by Axis troops, they were taken over by Italians in December 1942. "Saphir" was renamed "FR 112", and "Turquoise", "FR 116". These ships were unusable and disarmed remained in Bizerte until the end of activities in Africa. Shortly before surrendering, the Italians sank them. Only "Rubis" survived the war and was withdrawn from service on October 4, 1949.
