Gregorio García de la Cuesta

Gregorio García de la Cuesta y Fernández de Celis (May 9, 1741 – 1811) was a prominent Spanish general of the Peninsular War.

Born in La Lastra, Cantabria, to a family of petty nobles, Cuesta entered military service in 1758 as a member of the Spanish Royal Guards Regiment. He saw several successes as a Lieutenant General during the War of the Pyrenees in the years 1793 to 1795. On 20 December 1795, he led 8,000 Spanish and Portuguese in a successful attack in the Battle of Collioure, capturing Collioure, Fort Saint-Elme and Port-Vendres. Cuesta's force killed or captured 4,000 of the 5,000 defenders. He led a division under José de Urrutia y de las Casas at the successful Battle of Bascara on 14 June 1795. His corps of 7,000 to 9,000 troops captured 1,500 Frenchmen at Puigcerdà on 26 July. The following day, he fell upon and seized the town of Bellver with its 1,000-man French garrison. Unknown to Cuesta, both actions occurred after the Peace of Basel had been signed on 22 July 1795. Political intrigues prevented further advancement until the turmoil of 1805 produced his appointment to Commander in Chief of the Army of Castile.

When war with France broke out in 1808, Cuesta was already 67 years old, his army was ramshackle, ill-trained and underequipped. His hastily recruited force of 5,000 militia stood little chance against the Grande Armée and was heavily defeated at Cabezón, forcing Cuesta's withdrawal from his seat of command at Valladolid.
