When World War I began in August 1914, she was assigned to patrol the English Channel to enforce the blockade of Germany. "Amiral Aube" was transferred to the Eastern Mediterranean in late 1915 where she patrolled off the coast of Ottoman-controlled territory. To help protect Allied shipping from German commerce raiders, the ship was transferred to the French West Indies in mid-1916. In early 1918, "Amiral Aube" was briefly assigned to escort convoys from the West Indies to Europe. The ship was sent to Murmansk in March to support Allied forces when they intervened in the Russian Civil War. Returning home in October, she joined her sisters in the Atlantic Division () in early 1919. "Amiral Aube" was placed in reserve in 1920 and sold for scrap four years later.
