The French cruiser Pothuau was an armoured cruiser built for the French Navy in the 1890s. She spent most of her active career in the Mediterranean before becoming a gunnery training ship in 1906. The ship participated in the Kamerun campaign early in World War I before she was transferred to the Red Sea and the Indian Ocean in 1916 where she patrolled and escorted convoys. Pothuau fruitlessly searched the Indian Ocean for the German commerce raider Wolf in mid-1917. The ship resumed her previous role after the war until she was decommissioned in 1926 and sold for scrap three years later.

Jauréguiberry was a pre-dreadnought battleship constructed for the French Navy in the 1890s. Built in response to a naval expansion program of the British Royal Navy, she was one of a group of five roughly similar battleships, including Masséna, Bouvet, Carnot, and Charles Martel. Jauréguiberry was armed with a mixed battery of 305 mm (12 in), 274 mm (10.8 in) and 138 mm (5.4 in) guns. Constraints on displacement imposed by the French naval command produced a series of ships that were significantly inferior to their British counterparts, suffering from poor stability and a mixed armament that was difficult to control in combat conditions.
