Ramón Franco, who was in the Air Force at the time of the proclamation of the Second Spanish Republic, said: "Our little colonies —referring to the small outposts in the Moroccan shores, the Western Sahara and Equatorial Guinea— don't need a strong navy made up of large and numerous units.
Life in the high echelons of the Spanish Navy was more glamorous than among Army and Air Force officers, for it often included Yacht Club membership, with regattas, gala dinners and balls.
They cast a dim eye on the reforms of the armed forces introduced by newly nominated Republican Minister of War Manuel Azaña within the first few months of the new government.
In order to oppose and neutralize this movement, Eugenio Rodríguez Sierra, an officer of the Spanish Republican Navy was instrumental in the foundation of the Military Antifascist Union Unión Militar Antifascista (UMA).
The failure of the coup, especially in the main cities, Madrid, Barcelona, Bilbao and Valencia, along with the collapse of authority and the lack of agreement in the first brief negotiations, were only some of the factors that made the conflict drift towards open war.
José Giral's government tried to put together a Volunteer Army based on the units that had remained loyal, but the urgency of the moment played in favor of the formation of popular militias that were armed by parties and trade unions.
The takeover of the Navy by coup leaders failed mainly because the messages calling for a rebellion against the Spanish Republic were not sent in code, as would have been the norm, from Ciudad Lineal to the senior officers commanding the ships.
[16] The Third Reich and Italian Fascist military provided decisive support for General Franco's fraction of the army, so that the Spanish Republican Navy was unable to keep the blockade of the Strait of Gibraltar.
Thus, on 5 August 1936, the so-called Convoy de la victoria was able to bring at least 2,500 men of the Army of Africa from Spanish Morocco to Peninsular Spain breaking the republican blockade.
[17] From August 6 rebel transport ships crossed the Strait of Gibraltar, with the cover of Italian bombers and republican Churruca-class destroyer Alcalá Galiano was attacked and hit by Fascist aircraft while steaming back to Málaga.
Nevertheless, the same British governing bodies authorized the passage of food, goods and gasoline for the Nazi German transport planes and their crews in Spanish Morocco.
[25] By late 1937, however, the whole northern coast was lost following the fall of Asturias and many ships were seized by the rebels, including destroyer Císcar, which after being refurbished was made part of the Nationalist Navy.
President Manuel Azaña could not hide his disappointment, acknowledging in his memories the indecisiveness of the former commander of the Spanish Republican Navy despite having a greater number of ships.
[26] The fact, however was that both commanders of the fleet were only in their thirties and had been hurriedly promoted by Defence Minister Indalecio Prieto owing to the lack of loyal top officers.
Under Luis González de Ubieta's command the Republican Navy concentrated in the protection of maritime convoys that were supplying the internationally isolated Spanish Republic, as well as in the training of naval officers and their ships' crews.
[29] The Distintivo de Madrid, which had been established by the Spanish Republic in order to reward courage,[30] was given to cruisers Libertad and Méndez Núñez, and destroyers Lepanto, Almirante Antequera and Sánchez Barcáiztegui, as well as to their crew members.
On 5 March 1939, Spanish Republican Army Colonel Segismundo Casado made an anticommunist coup and proclaimed a (Consejo Nacional de Defensa).
On the same day the Nationalist Air Force bombed the harbour of Cartagena, the main base of the Republican Navy, sinking destroyer Sanchez Barcaiztegui.
[35] In the last months of the war some of the steamers belonging to the Compañía Transatlántica Española and Trasmediterránea companies were requisitioned by the Republican Navy and were used for evacuating refugees from coastal cities besieged by the Francoist armies.
In 1920 the air arm of the navy, already established through a Royal decree four years earlier, became functional in El Prat, in the same location as present-day Barcelona Airport.
Newly nominated Minister of War Manuel Azaña planned eventually to disband the marine corps as part of his hasty reforms of the Spanish armed forces.
