French battleship Jauréguiberry

''Jauréguiberry'' was a pre-dreadnought battleship constructed for the French Navy (french: Marine Nationale) 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 , and 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.

In peacetime the ship participated in routine training exercises and cruises in the Mediterranean Sea, primarily as part of the Mediterranean Squadron. The ship was involved in several accidents, including a boiler explosion and an accidental torpedo detonation that delayed her entry into service in 1897. Two more torpedo explosions occurred in 1902 and 1905, and she ran aground during a visit to Portsmouth in August 1905. By 1907, she had been transferred to the Reserve Division, although she continued to participate in maneuvers and other peacetime activities.

Following the outbreak of World War I in July 1914, ''Jauréguiberry'' escorted troop convoys from North Africa and India to France. She supported French troops during the Gallipoli Campaign, including during the landing at Cape Helles in April 1915, before she became guardship at Port Said from 1916 until the end of the war. Upon her return to France in 1919 she became an accommodation hulk until 1932. The ship was sold for scrap in 1934.

Background and design

In 1889, the British Royal Navy passed the Naval Defence Act, which resulted in the construction of the eight s; this major expansion of naval power led the French government to respond with the ''Statut Naval'' (Naval Law) of 1890. The law called for twenty-four "''cuirasses d'escadre''" (squadron battleships) and a host of other vessels, including coastal-defense battleships, cruisers, and torpedo boats. The first stage of the program was to be a group of four squadron battleships built to different designs, but meeting the same basic requirements, including armor, armament, and displacement.

The naval high command issued the basic characteristics on 24 December 1889; displacement should not exceed , the main battery was to consist of and guns, the belt armor should be , and the ships should maintain a top speed of . The secondary armament was to be either or caliber, with as many guns fitted as space would allow.

The basic design for the ships was based on the previous battleship , but instead of mounting the main battery all on the centerline, the ships used the lozenge arrangement of the earlier vessel , which moved two of the main battery guns to single turrets on the wings. Although the navy had stipulated that displacement could be up to 14,000 metric tons, political considerations, namely parliamentary objections to increases in naval expenditures, led the designers to limit displacement to around .

Five naval architects submitted proposals to the competition. The design for ''Jauréguiberry'' was prepared by Amable Lagane, the director of naval construction at the Forges et Chantiers de la Méditerranée shipyard in La Seyne-sur-Mer. Lagane had previously supervised the construction of the ''Magenta''-class ironclad , which influenced his design for ''Jauréguiberry''. Though the program called for four ships to be built in the first year, five were ultimately ordered: ''Jauréguiberry'', , , , and . ''Jauréguiberry'' used a very similar hull form to ''Marceau''s, and as a result, was shorter and wider than the other vessels.

The design for ''Jauréguiberry'' was also influenced by the Chilean battleship , then under construction in France (and which also had been designed by Lagane). A small vessel, ''Capitán Prat'' had adopted twin-gun turrets for her secondary battery to save space that would have been taken up by traditional casemate mountings. Lagane incorporated that solution in ''Jauréguiberry'', though she was the only French battleship of the program to use that arrangement owing to fears that the rate of fire would be reduced and that the turrets would be more vulnerable to being disabled by a single lucky hit. She was the first French battleship to use electric motors to operate her main-battery turrets.

She and her half-sisters were disappointments in service; they generally suffered from stability problems, and Louis-Émile Bertin, the Director of Naval Construction in the late 1890s, referred to the ships as "chavirables" (prone to capsizing). All five of the vessels compared poorly to their British counterparts, particularly their contemporaries of the . The ships suffered from a lack of uniformity of equipment, which made them hard to maintain in service, and their mixed gun batteries comprising several calibers made gunnery in combat conditions difficult, since the splashes of relatively similarly sized shells were hard to differentiate and thus made it difficult to calculate corrections to hit the target. Many of the problems that plagued the ships in service were a result of the limitation on their displacement, particularly their stability and seakeeping.

General characteristics and machinery

''Jauréguiberry'' was long overall. She had a maximum beam of and a draft of . She displaced at normal load and at full load. She was fitted with two heavy military masts with fighting tops. In 1905 her captain described her as an excellent sea-boat and a good fighting ship, although her secondary armament was too light. He also said that she was stable and well laid-out with good living conditions. She had a crew of 631 officers and enlisted sailors.

''Jauréguiberry'' had two vertical triple-expansion steam engines, also built by Forges et Chantiers de la Méditerranée, which were designed to give the ship a speed of . On trials they developed and drove the ship to a maximum speed of . Each engine drove a propeller. Twenty-four Lagraffel d'Allest water-tube boilers provided steam for the engines at a pressure of . The boilers were distributed between six boiler rooms and were ducted into a pair of closely spaced funnels. She normally carried of coal, but could carry a maximum of . This gave her a radius of action of at .

Armament

''Jauréguiberry''s main armament consisted of two 45-caliber Canon de Modèle 1887 guns in two single-gun turrets, one each fore and aft of the superstructure. A pair of 45-caliber Canon de Modèle 1887 guns were mounted in single-gun wing turrets, one amidships on each side, sponsoned out over the tumblehome of the ship's sides. Each 305 mm turret had an arc of fire of 250°. The 305 mm guns fired cast iron (CI) projectiles, or heavier armor-piercing (AP) and semi-armor-piercing (SAP) shells at a muzzle velocity of . The 274 mm guns were also supplied with a mix of CI, AP, and SAP shells, with the same muzzle velocity as the larger guns. The ship's offensive armament was completed by a secondary battery of eight 45-caliber Canon de Modèle 1891 guns mounted in manually operated twin-gun turrets. The turrets were placed at the corners of the superstructure with 160° arcs of fire. They fired CI or AP or SAP shells at a muzzle velocity of .

Defense against torpedo boats was provided by a variety of light-caliber weapons. Sources disagree on the number and types, possibly indicating changes over the ship's lifetime. All sources agree on four 50-caliber ( ) guns. These fired a shell at a muzzle velocity of . Gibbons and Gardiner agree on twelve, later eighteen, although d'Ausson lists fourteen, 40-caliber Canon de 47 mm Modèle 1885 Hotchkiss guns that were mounted in the fighting tops and on the superstructure. They fired a projectile at to a maximum range of . Their theoretical maximum rate of fire was fifteen rounds per minute, but only seven rounds per minute sustained. Gibbons and Gardiner agree that eight Hotchkiss 5-barrel revolving guns were mounted on the fore and aft superstructures, although none are listed by d'Ausson.

The ship was initially fitted with torpedo tubes, though sources disagree on the number. Gardiner states that she had two submerged tubes and two above-water tubes, but d'Ausson states that she had six tubes, two each above water in the bow and stern and one on each broadside underwater. The above-water tubes were removed during a refit in 1906. The M1892 torpedoes carried a warhead, and could be set at or , which could reach targets at or , respectively.

Armor

''Jauréguiberry'' had a total of of nickel-steel armor; equal to 33.5% of her normal displacement. Her waterline belt ranged from in thickness. Above the belt was a thick strake of side armor that created a highly divided cofferdam. Around the above-water torpedo tubes, the upper strake increased to . The armored deck rested on the top of the waterline belt. Her 305 mm gun turrets were protected by of armor on the sides and faces while her 274 mm turrets had of armor. The ship's secondary turrets were protected by of armor. The walls of her conning tower were thick.

Service

''Jauréguiberry'' was ordered on 8 April 1891 and laid down on 23 April at Forges et Chantiers de la Méditerranée in La Seyne-sur-Mer. She was launched on 27 October 1893 and was complete enough to begin her sea trials on 30 January 1896. A tube in one of her boilers burst on 10 June during a 24-hour engine trial, killing six and wounding three. Two months later she suffered an accident while testing her main armament. She was finally commissioned on 16 February 1897, although the explosion of a torpedo's air chamber on 30 March delayed her assignment to the Mediterranean Squadron until 17 May. During this period, she was fitted with a new electric order-transmission system that relayed instructions from the ship's fire-control center to the guns, a marked improvement over the voice tubes that were in standard use in the world's navies at the time. Immediately on entering service, she and her half-sisters ''Charles Martel'' and ''Carnot'' were sent to join the International Squadron that had been assembled beginning in February. The multinational force also included ships of the Austro-Hungarian Navy, the Imperial German Navy, the Italian '' Regia Marina'', the Imperial Russian Navy, and the British Royal Navy, and it was sent to intervene in the 1897–1898 Greek uprising on Crete against rule by the Ottoman Empire.

Throughout the ship's peacetime career, she was occupied with routine training exercises, which included gunnery training, combined maneuvers with torpedo boats and submarines, and practice attacks on coastal fortifications. One of the largest of these exercises was conducted between March and July 1900, and involved the Mediterranean Squadron and the Northern Squadron. On 6 March, ''Jauréguiberry'' joined the battleships ''Brennus'', , , ''Charles Martel'', and ''Bouvet'' and four protected cruisers for maneuvers off Golfe-Juan, including night-firing training. Over the course of April, the ships visited numerous French ports along the Mediterranean coast, and on 31 May the fleet steamed to Corsica for a visit that lasted until 8 June. After completing its own exercises in the Mediterranean, the Mediterranean Squadron rendezvoused with the Northern Squadron off Lisbon, Portugal, in late June before proceeding to Quiberon Bay for joint maneuvers in July. The maneuvers concluded with a naval review in Cherbourg on 19 July for President Émile Loubet. On 1 August, the Mediterranean Squadron departed for Toulon, arriving on 14 August.

On 20 January 1902 the air chamber of another torpedo exploded, killing one sailor and wounding three. In September she transported the Minister of the Navy to Bizerte. By this time, the ship had been assigned to the 2nd Battle Division of the Mediterranean Squadron, along with ''Bouvet'' and the new battleship , the latter becoming the divisional flagship. In October, ''Jauréguiberry'' and the rest of the Mediterranean Squadron battleships steamed to Palma de Mallorca, and on the return to Toulon they conducted training exercises. ''Jauréguiberry'' was transferred to the Northern Squadron in 1904, her place in the Mediterranean Squadron being taken by the new battleship . ''Jauréguiberry'' arrived at Brest on 25 March. She was lightly damaged when she touched a rock while entering Brest in fog on 18 July and, in another incident, her steering compartment was flooded when a torpedo air chamber burst between her screws during a torpedo-launching exercise on 18 May 1905.

While visiting Portsmouth on 14 August, ''Jauréguiberry'' ran aground for a short time in the outer harbor. She returned to the Mediterranean Squadron in February 1907 where she was assigned to the Reserve Division, and the following year was reassigned to the 3rd Division. On 13 January 1908, she joined the battleships , , ''Gaulois'', ''Charlemagne'', , and ''Masséna'' for a cruise in the Mediterranean, first to Golfe-Juan and then to Villefranche-sur-Mer, where the squadron stayed for a month. In 1909, the 3rd and 4th Divisions were reformed into the 2nd Independent Squadron and transferred to the Atlantic in 1910. Beginning on 29 September 1910 her boiler tubes were renewed in a four-month refit at Cherbourg. On 4 September 1911, she participated in a naval review off Toulon. In October 1912 the Squadron was reassigned to the Mediterranean Squadron and a year later, in October 1913, ''Jauréguiberry'' was transferred to the Training Division. During this period, she was fitted with an experimental fire-control system as part of a series of tests before it was installed in the new dreadnought battleships. She became the flagship of the Special Division in April 1914; in August, the commander of the division was ''Contre-amiral'' (Rear Admiral) Darrieus. At that time, the division also included the battleship ''Charlemagne'' and the cruisers and .

World War I

Following the outbreak of World War I in July 1914, France announced general mobilization on 1 August. The next day, Admiral Augustin Boué de Lapeyrère ordered the entire French fleet to begin raising steam at 22:15 so the ships could sortie early the next day. The bulk of the fleet, including the ''Division de complément'', was sent to French North Africa, where they escorted the vital troop convoys carrying elements of the French Army from North Africa back to France to counter the expected German invasion. The French fleet was tasked with guarding against a possible attack by the German battlecruiser , which instead fled to the Ottoman Empire. As part of her mission, ''Jauréguiberry'' was sent to Oran, French Algeria on 4 August, in company with ''Bouvet'', ''Suffren'', and ''Gaulois''. She also escorted a convoy of Indian troops passing through the Mediterranean in September. Beginning in December, ''Jauréguiberry'' was stationed at Bizerte, remaining there until February 1915 when she sailed to Port Said to become flagship of the Syrian Division, commanded by Admiral Louis Dartige du Fournet. At that time, the division included ''Saint Louis'', the coast defence battleship , and ''D'Entrecasteaux''.

On 25 March, ''Jauréguiberry'' departed Port Said for the Dardanelles, where the French and British fleets were attempting to break through the Ottoman defenses guarding the straits. An earlier Anglo-French attack on 18 March had cost the French fleet the battleship ''Bouvet'', and two other battleships—''Suffren'' and ''Gaulois''—had been badly damaged and forced to withdraw. To make good his losses, Admiral Émile Guépratte requested that ''Jauréguiberry'' and ''Saint Louis'' be transferred to his command. On 1 April, Guépratte transferred his flag from ''Charlemagne'' to ''Jauréguiberry''. By late May, the French squadron had been restored to effective strength, and included the battleships ''Saint Louis'', ''Charlemagne'', ''Patrie'', ''Suffren'', and ''Henri IV''. The formation was designated the 3rd Battle Division. ''Jauréguiberry'' provided gunfire support to the troops during the Landing at Cape Helles on 25 April, during which the French forces made a diversionary landing on the Asian side of the straits. During the operation, ''Jauréguiberry'' and the other French ships kept the Ottoman guns on that side of the strait largely suppressed, and prevented them from interfering with the main landing at Cape Helles. She continued operations in the area until 26 May, including supporting the Allied attack during the Second Battle of Krithia on 6 May. She was lightly damaged by Turkish artillery on 30 April and 5 May, but continued to fire her guns as needed.

''Jauréguiberry'' was recalled to Port Said on 19 July and bombarded Ottoman-controlled Haifa on 13 August. She resumed her role as flagship of the Syrian Division on 19 August. The ship participated in the occupation of Ile Rouad on 1 September and other missions off the Syrian coast until she was transferred to Ismailia in January 1916 to assist in the defense of the Suez Canal, although she returned to Port Said shortly afterward. ''Jauréguiberry'' was refitted at Malta between 25 November and 26 December 1916, thereafter returning to Port Said. She landed some of her guns to help defend the canal in 1917 and was reduced to reserve in 1918. The ship arrived at Toulon on 6 March 1919 where she was decommissioned and transferred to the Engineer's Training School on 30 March for use as an accommodation hulk. She was struck from the Navy List on 20 June 1920, but remained assigned to the Engineer's School until 1932. ''Jauréguiberry'' was sold for scrap on 23 June 1934 for the price of 1,147,000  francs.
