Cosme Damián de Churruca

Cosme Damián de Churruca y Elorza (1761–1805) was a Basque Spanish Navy officer and hydrographer born at Mutriku in Gipuzkoa. He entered the naval academy at Cádiz in 1776, surveyed the Strait of Magellan in 1788–1789 and charted the Antilles on a royal cartographic expedition of 1792–1795.

In 1805, as a brigadier, he commanded the ship San Juan Nepomuceno at Trafalgar. Mortally wounded, he forbade his officers to surrender and died on deck still giving orders. He was posthumously promoted to admiral, and his cousin was made Count of Churruca.
