Spanish battleship Jaime I

''Jaime I'' was a Spanish dreadnought battleship, the third and final member of the , which included two other ships: and . Named after King James I of Aragon, ''Jaime I'' was built in the early 1910s, though her completion was delayed until 1921 owing to a shortage of materials that resulted from the start of World War I the previous year. The class was ordered as part of a naval construction program to rebuild the fleet after the losses of the Spanish–American War in the context of closer Spanish relations with Britain and France. The ships were armed with a main battery of eight guns and were intended to support the French Navy in the event of a major European war.

By the time ''Jaime I'' was completed, the Rif War had broken out in the Spanish protectorate in Morocco and the ship was used to support Spanish forces fighting in the colony in the early to mid-1920s. She was placed in reserve in 1931 after the proclamation of the Second Spanish Republic, but was reactivated in 1933 to serve as the fleet flagship. Plans to modernize the vessel in the mid-1930s came to nothing after the start of the Spanish Civil War in July 1936. ''Jaime I'' and the bulk of the fleet remained loyal to the republican government, though her sister ''Alfonso XIII'' (by then having been renamed ''España''), fell under rebel control. The Spanish Republican Navy nevertheless failed to make effective use of its naval superiority and ''Jaime I'' did not see significant action apart from bombarding Nationalist positions in North Africa. She was attacked twice by enemy aircraft during the war, and in June 1937, an accidental fire aboard the ship caused an internal explosion that destroyed the ship. Some of her guns were salvaged and mounted in coastal batteries after the war and remain extant, though no longer in use.

Design

Following the destruction of much of the Spanish fleet in the Spanish–American War of 1898, the Spanish Navy made a series of failed attempts to begin the process of rebuilding. After the First Moroccan Crisis strengthened Spain's ties to Britain and France and public support for rearmament increased in its aftermath, the Spanish government came to an agreement with those countries for a plan of mutual defense. In exchange for British and French support for Spain's defense, the Spanish fleet would support the French Navy in the event of war with the Triple Alliance. A strengthened Spanish fleet was thus in the interests of Britain and France, which accordingly provided technical assistance in the development of modern warships, the contracts for which were awarded to the firm Spanish '' Sociedad Española de Construcción Naval'' (SECN), which was formed by the British shipbuilders Vickers, Armstrong Whitworth, and John Brown & Company. The vessels were authorized some six months after the British had completed the "all-big-gun" , and after discarding plans to build pre-dreadnought-type battleships, the naval command quickly decided to build their own dreadnoughts.

''Jaime I'' was long at the waterline and long overall. She had a beam of and a draft of ; her freeboard was amidships. The ship displaced as designed and up to at full load. Her propulsion system consisted of four-shaft Parsons steam turbines driving four screw propellers, with steam provided by twelve Yarrow boilers. The engines were rated at and produced a top speed of . ''Jaime I'' had a cruising radius of at a speed of . Her crew consisted of 854 officers and enlisted men.

''Jaime I'' was armed with a main battery of eight 50-caliber guns, mounted in four twin gun turrets. One turret was placed forward, two were positioned en echelon amidships, and the fourth was aft of the superstructure. This mounting scheme was chosen in preference to superfiring turrets, as was done in the American s, to save weight and cost. For defense against torpedo boats, she carried a secondary battery that consisted of twenty guns mounted individually in casemates along the length of the hull. They were too close to the waterline, however, which made them unusable in heavy seas. She was also armed with four 3-pounder guns and two machine guns. Her armored belt was thick amidships; the main battery turrets were protected with the same amount of armor plate. The conning tower had thick sides. Her armored deck was thick.

Service history

Construction and the Rif War

''Jaime I'', named for the 13th century James I of Aragon, was laid down at the SECN shipyard in Ferrol on 5 February 1912. She was launched on 21 September 1914, less than two months after the start of World War I. Spain remained neutral during the conflict, but because Britain supplied much of the armament and other building materials, work on ''Jaime I'' was considerably delayed. She was largely complete by early 1915, by which time she only lacked her main battery guns and mounts, which could not be delivered owing to the war. She underwent initial machinery testing in May 1915, and the ship was ready to go to sea by 1917, but she was not completed until well after the end of the war. She conducted sea trials in May 1921, slightly exceeding on speed tests, and work was finally finished on 20 December. Upon her completion, she joined her two sister ships in the 1st Squadron of the Spanish fleet.

Throughout the early 1920s, she provided fire support to the Spanish Army in its campaigns in Morocco during the Rif War that had broken out in mid-1921. Her sister ship was wrecked during operations off Morocco in 1923. During this period, tensions over the European colonial holdings in North Africa—predominantly stoked by Italy's fascist leader Benito Mussolini over the perceived lack of prizes for Italy's eventual participation in World War I on the side of Britain and France—had led to a rapprochement between Italy and Spain in 1923, which was at that time ruled by the dictator Miguel Primo de Rivera. Primo de Rivera sent a fleet consisting of ''Jaime I'', her sister , the light cruiser , two destroyers, and four submarines to visit the Italian fleet in late 1923. They departed Valencia on 16 November and stopped in La Spezia and Naples, arriving back in Barcelona on 30 November.

Rif insurgents operating a coastal artillery battery damaged ''Jaime I'' in 1924. By 1925, the Rif rebels had widened the war by attacking French positions in neighboring French Morocco. Spain and France planned a major landing at Alhucemas, consisting of some 13,000 soldiers, 11 tanks, and 160 aircraft, to attack the core rebel territory in September. The Spanish Navy supplied ''Jaime I'', ''Alfonso XIII'', four cruisers, a seaplane tender, and several smaller craft. The French added the battleship , two cruisers, and several other vessels. Both fleets provided gunfire support as the ground forces landed on 8 September; the amphibious assault was a success, and after heavy fighting over the next two years, the Rifian rebels were defeated. In the final days of the conflict in October 1927, Alfonso XIII, his wife, and a number of generals, including Primo de Rivera, Francisco Franco, Dámaso Berenguer, and Ricardo Burguete, traveled to Morocco to tour the pacified colony. They came aboard ''Jaime I'' at Algeciras, Spain and crossed to Ceuta in Morocco on 5 October. After completing their tour, they returned to the ship on 10 October to be taken back to Spain.

Early 1930s

By the early 1930s, the effects of the Great Depression had spurred significant domestic opposition to the regime of Primo de Rivera, leading to his resignation on 28 January, and ultimately to Alfonso XIII's exile in April 1931. Immediately thereafter, the government of the Second Spanish Republic began a series of cost-cutting measures to offset the deficits that had been incurred during the Rif War, and as a result, both ''España'' and ''Jaime I'' were placed in reserve in Ferrol on 15 June. ''Jaime I'' was recommissioned on 20 April 1933 to serve as the fleet flagship. Plans to modernize the ''España''-class battleships traced their origin to the 1920s, but the increased risk of conflict with Italy by the mid-1930s put increased pressure to begin the work. One proposal, advanced in 1934, advocated rebuilding the ships into analogues to the German s with new oil-fired boilers. The ships' hulls would have been lengthened, and the main battery turrets rearranged so they would all be on the centerline. The ships' secondary batteries would have been replaced with dual-purpose (DP) guns. The plan ultimately came to nothing.

The finalized plan for ''Jaime I'' and ''España'' involved increasing the height of the wing turrets' barbettes, improving their fields of fire and allowing them to fire over the new secondary battery, which was to consist of twelve 120 mm DP guns placed on the upper deck in open mounts. A new anti-aircraft battery of either ten or eight guns were to be fitted. Other changes were to be made to improve fire-control systems, increase crew accommodation spaces, and install anti-torpedo bulges, among other improvements. Work on both vessels was slated to begin in early 1937, but the scheduled modernization was interrupted by the Spanish coup of July 1936, which plunged the country into the Spanish Civil War.

Spanish Civil War

In mid-July 1936, ''Jaime I'' was moored in Vigo; she was at that time the only battleship capable of going to sea, as her sister ''España'' was being repaired in Ferrol. Franco, the leader of the Nationalist coup against the government, relied on defections from the Navy to carry the Army of Africa to Spain. The ships' crews in Ferrol already knew about the plans by 13 July, and many attended a meeting that day to discuss what course of action they would take if the officer corps joined Franco when he launched the coup. On the morning of 18 July, wireless operators in the navy headquarters Madrid intercepted radio messages from Franco to rebels in Morocco; they alerted naval headquarters, which in turn sent messages to every ship in the fleet to alert the crews to watch for rebellious officers. The crews in Cartagena, including ''Jaime I'', mutinied after their commanders began to join the Nationalists, murdering many of them and ensuring the ships would remain under government control in the Spanish Republican Navy. ''Jaime I'' avoided the worst of the bloodshed, as her commander opted to remain loyal to the government.

''Jaime I'' got underway on 19 July to attempt to block the crossing, joining other elements of the fleet off Gibraltar later that day. Despite the fact that the Republican government had retained most of the fleet in the Mediterranean, it was unable to block the passage of the Army of Africa to Spain. The vessels were crippled by poor discipline for some time, as they had had few remaining officers and the crews distrusted those that were not killed. In addition, the German ''Kriegsmarine'' (War Navy) had sent the heavy cruisers and to protect the convoys of transport ships that carried heavy weapons. And significant numbers of soldiers were carried by Junkers Ju 52 transport aircraft covertly supplied by the Nazis through the dummy corporation '' Sociedad Hispano-Marroquí de Transportes'' (Spanish-Moroccan Transport Company).

In the first months of the war, ''Jaime I'' shelled a number of rebel strongholds, among them Ceuta, Melilla, and Algeciras. In Algeciras, she scored hits with her secondary armament on the Nationalist gunboat , which was burned down to the waterline, although she was later repaired and returned to service. On 13 August, ''Jaime I'' was damaged by a Nationalist air attack at Málaga; a pair of bombers from the German Condor Legion attacked the vessel early that morning. They scored a hit with a small bomb that struck the ship in the bow and caused minimal damage.

The elements of the Spanish fleet that had been moored in Ferrol were seized by Nationalist forces at the start of the revolt; these ships included ''España'', which was used to enforce a blockade of the northern Spanish ports of Gijón, Santander, and others. In response to these operations, the Republicans deployed a flotilla of five submarines from the Mediterranean, though one was sunk by Nationalist forces en route. They also briefly deployed ''Jaime I'', a pair of light cruisers, and six destroyers to Gijón, arriving on 25 September.

On 2 October, sailors from ''Jaime I'', having learned that the destroyer had been sunk by the Nationalists, took revenge by marching to the prison ship in the estuary of Bilbao and executing dozens of prisoners who had been arrested for sympathies with the rebels. Some of the sailors were in turn executed by the Basque Government and the battleship was ordered to leave the port of Bilbao. It puts the assault on 25th September.

The squadron departed already on 13 October without having attacked ''España'' or any other elements of the Nationalist fleet. For their part, the Nationalists avoided confronting the Republican ships, owing in large part to the significantly better condition of ''Jaime I'' compared to ''España'', the latter having only three of her four turrets in operation. When the Republican ships departed, they left behind two of the submarines and one of the destroyers, and some of ''Jaime I''s secondary guns were dismounted, later to be installed on four fishing boats.

In early 1937, ''Jaime I'' was dry docked in Cartagena for repairs after a recent grounding. A group of five Savoia-Marchetti SM.79 bombers of the Italian ''Aviazione Legionaria'' attacked on 21 May after she had been re-floated. Republican anti-aircraft fire was ineffective and failed to prevent the bombers from making two runs on the ship, dropping around sixty bombs in total. Reports of their success vary; the military historian Albert Nofi states that they scored three hits that caused only minor damage, while the historian Marco Mattioli states that the attack resulted in two hits, two near misses on her starboard side and three more on the quay to which she was moored, disabling the ship.

On 17 June, while at Cartagena, she was destroyed by an accidental internal explosion and fire, although sabotage was suspected. Some 200 men were killed in the explosion. She was refloated, but determined to be beyond repair. She was officially discarded on 3 July 1939 and was subsequently broken up for scrap. All the guns were recovered from the wreck and were erected in coastal artillery batteries in 1940 near Tarifa to cover the Strait of Gibraltar. Four of her guns, from the fore and aft turrets, were mounted two apiece at the Vigia Battery (D-9) and the Cascabel Battery (D-10). Each battery consisted of a concrete emplacement that included a magazine and a separate command post. Both batteries were abandoned in 1985 but are still present, albeit in a state of degradation owing to a lack of maintenance.
