He received his early years education in the Seminary of Burgos. Then, he entered the School of Bergara. Once he finished his studies, he joined the Naval Academy of Cadiz in 1776, and got his degree in the Naval Academy of Ferrol in 1778, becoming a naval officer. In 1781, Cosme Damián de Churruca, as an officer of the Spanish Navy, performed heroically in a siege of Gibraltar. , Prado Museum In 1805, a few months before his death, Churruca married María Dolores Ruiz de Apodaca, niece of Juan Ruiz de Apodaca, in 1797. Doña María was only 19 when Churruca died.
Battle of Trafalgar
The squadron to which the San Juan was assigned sailed on 13 August from the port of Ferrol. General Gravina had given Churruca a place of honour, the head of the vanguard. Churruca completed his mission with the highest merit and upon his arrival to Cadiz, redoubled his efforts in training his recently recruited and inexperienced civilian crew. It was at this time he married Maria de los Dolores Ruiz de Apodaca, daughter of Brigadier don Vicente, and cousin of the duke of Venadito. , manufactured by Nicolas Noël Boutet.|left With the Spanish and French squadrons reunited in the port of Cadiz, they sailed on a course to Marticina, where they took the fort of Del Diamante and captured a British convoy consisting of 16 merchant ships; in these moments Villeneuve, the chief of the combined fleet, was informed of the presence of Nelson in the Antillas. Villeneuve now decided he had completed his objective, which was to draw British naval forces to the other shore of the Atlantic, so he decided to sail the combined fleet back to Ferrol. However, in the cape of Finisterre, he bumped into the squadron of Admiral Calder, where a battle ensued. The majority of the French squadron continued to Ferrol, while the remaining ships were left to fend for themselves. Their defeat is attributed to the indecision and poor command of the chief of the combined squadron, Villeneuve, by Napoleon, who upon reading reports of the battle said: "The Spanish have behaved like lions, while their admiral only offered curses." The combined fleet entered Ferrol after the battle, proceeding in continuation to La Coruña. From this port, Villeneuve set a course to Cadiz, ignoring Napoleon’s order to go to Brest. Once there, despite the protests and opposing opinions of Churruca, Gravina and Alcalá-Galiano, Villeneuve abandoned the Bay of Cádiz to reach Nelson at the Cape of Trafalgar on 21 October 1805. Before sailing on 20 October, Churruca wrote to his brother: 21 October dawned, and in sight of the British fleet Churruca ordered the colours to be nailed to the mast, and ordered that they should not be taken down while he still lived. Under the command of Churruca, the San Juan Nepomuceno demonstrated military precision, daring and efficiency, despite finding itself alone against six English ships, including HMS Defiance, HMS Tonnant, HMS Bellerophon and HMS Dreadnought. After being reached by a cannonball which tore his leg, Churruca died with the admiration of his enemies, who displayed his vessel in Gibraltar to visitors with his name written in golden letters above the cabin, and advising those who would enter to remove their covers, as if don Cosme Damián de Churruca y Elorza was still present. His officers kept their word, and only lowered the colours after his death. Unable to break the circle of fire and in order to prevent the vessel sinking with all wounded trapped below, the San Juan yielded with over 100 dead and 150 wounded on board.
Legacy
Churruca was posthumously promoted to admiral, and in his memory his cousin received the title Count of Churruca. The events to which Churruca was a protagonist, were novelised in 1872 by Benito Pérez Galdós, in Trafalgar, the first title of his Episodios Nacionales. . A statue in his memory stands in his native Mutriku, as well as Ferrol, where a simple monument records his passing by the Academy. In San Fernando there is a stone in the third pulpit of the Panteon de Marinos Ilustres which reads: After Trafalgar, the ship was taken to Gibraltar and entered British service, initially as, before her Spanish name was restored. In honour of Churruca's courage, his cabin bore his name on a brass plate, and all who entered were required to remove their hat as a mark of respect for a gallant enemy. HMS San Juan served as a supply hulk in Gibraltar until 1815, when she was broken up. In the 1942 Spanish film Raza, based on a semi-autobiographical script by then head of stateFrancisco Franco, the main characters are a family descending from Churruca.
