Cosnie Damian Do Chirrcca Y Elorza, a Spanish naval officer, born at Motrico, in the province of Guipuzcoa, Sept. 27, 1701, died at Trafalgar, Oct. 21, 1805. He distinguished himself at the siege of Gibraltar in rescuing some of the survivors from the floating batteries, after the latter had been destroyed by the English. Having received an appointment in a Spanish surveying expedition to the strait of Magellan, he wrote an admirable diary of his exploration of Tierra del Fuego, which was published at Madrid in 1793. In 1791, being then in command of a frigate, he was placed at the head of an expedition fitted out for the purpose of surveying the coasts of the gulf of Mexico. The war which soon after broke out between Spain and France interrupted this work, and compelled Churruca to leave his task unfinished; but he had already completed 24 charts of the coasts of Cuba, Hayti, Porto Rico, etc, some of which have since been published. He was afterward sent as an envoy to Brest, and was received with distinction by Napoleon, then first consul.

In October, 1805, he was in command of a frigate at Cadiz, and shortly before the battle of Trafalgar wrote to a friend, "If you hear that my ship is taken, know for certain that I am dead." In that battle, his leg having been shot away by a cannon ball, he died three hours afterward.
