Ferrol,
Galicia, had been able to seize the city's
naval base in July 1936, but at a large cost: over 30 mutinous
officers had been shot dead by hundreds of sailors loyal to the Republic. Their prize included the old
battleship España (formerly ), the cruiser , the unfinished and , an older cruiser undergoing repairs (), 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 , 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
Baleares 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==
