Battle of Cape Spartel (1936)

The Battle of Cape Spartel (Cabo Espartel in Spanish) was a naval battle of the Spanish Civil War that broke the Republican blockade of the Strait of Gibraltar, securing the maritime supply route to Spanish Morocco for the Nationalists early in the war. The action occurred on September 29, 1936 between two Nationalist cruisers and two Republican destroyers.

Background
The rebels at Ferrol, Galicia, had been able to seize the city's naval base in July, but at a large cost: over 30 mutinous officers had been shot by hundreds of sailors loyal to the Republic.

Their prize included the old battleship España (formerly SPANISH BATTLESHIP Alfonso XIII), the cruisers SPANISH CRUISER Almirante Cervera and the unfinished Canarias, two light cruisers, one destroyer, and a number of torpedo boats and sloops. In September, a small squadron, including Almirante Cervera and Canarias, steamed from Ferrol to engage the Republican navy.

At the start of the war, the Spanish Republican Navy had the battleship SPANISH BATTLESHIP Jaime I, three light cruisers, 14 destroyers, plus five submarines. In addition to España, the two cruisers and one destroyer taken by the Nationalists, by the following year they had completed Almirante Cervera and Canarias. They also had purchased four destroyers and two submarines from Fascist Italy. The Nationalists established a blockade of the Republican-held coastline for the entire duration of the war, but their paucity of ships limited the blockade's effectiveness.

The battle
The Nationalists engaged a squadron of Republican destroyers stationed on the western end of the Straits shortly after 6:30 am. The destroyer Gravina was deployed near Cape Spartel, while her sister ship SPANISH DESTROYER Almirante Ferrándiz was patrolling off Ceuta. A fierce exchange of fire followed, during which the destroyer Almirante Ferrándiz was chased and eventually sunk by Canarias in the Alboran Sea after a 40-minute engagement, while Gravina was pursued and hit twice by Almirante Cervera along the Atlantic coast of Morocco. The main guns of Canarias found their mark at a range of 11 nmi with their second salvo, while those of Almirante Cervera performed poorly. The surviving Republican destroyer retreated toward Casablanca. Almirante Ferrándiz, having been hit six times, blew up and sank 18 nmi south of Calaburras. Thirty-one seamen from Almirante Ferrándiz were rescued by Canarias, while the French liner Koutubia picked up another 26, including her commander, José Luis Barbastro Jiménez. This action was decisive to open the Straits to the insurgents' shipping.
