Pedro Téllez-Girón, 9th Duke of Osuna

Spanish nobleman (1755–1807)

Pedro de Alcántara Téllez Girón y Pacheco, 9th Duke of Osuna, Grandee of Spain (8 August 1755 – 7 January 1807), was a Spanish nobleman and military commander during the French Revolutionary Wars.

His father, the 8th Duke, was Pedro Zoilo Téllez Girón y de Guzmán (27 June 1728 – 1 April 1787) and his mother was María Vicenta de la Portería Pacheco Téllez Girón (born 28 July 1735). In 1772, he married María Josefa Pimentel, 12th Countess Duchess of Benavente. She was 15th Countess of Benavente, Grandee of Spain, 13th Duchess of Béjar, Duchess of Arcos, Duchess of Gandía and Duchess of Monteagudo, Princess of Esquilache and Marquise of Lombay, whose possessions and noble titles were absorbed thereto by the Osuna family.

Téllez Girón held important commands during the War of the Pyrenees which began on 7 March 1793 and ended with the Peace of Basel on 22 July 1795. As a Lieutenant General, he commanded a column under Captain General Antonio Ricardos in the Battle of Mas Deu in the eastern Pyrenees on 19 May 1793. Soon after the battle, he transferred out of Ricardos' Army of Catalonia. He later fought in the western Pyrenees. In the fall of 1794, he was placed in charge of the defense of Navarre. The Army of the western Pyrenees under French General Bon Adrien Jeannot de Moncey defeated his badly outnumbered troops in the Battle of Orbaitzeta in October 1794, though he was able to keep the French from capturing the city of Pamplona.

In a famous portrait, Goya portrays the Duke of Osuna without any medals in front of a dark background. The only indication of his military background is the baton he holds. One of his children was Joaquina Téllez Girón, Marchioness of Santa Cruz, who was also portrayed by Goya. Another of the children from Goya's painting was Pedro de Álcantara Téllez Girón y Pimentel, (1786–1851), Principe de Anglona, Captain General of the Island of Cuba from 10 January 1840 to 7 March 1841, and who was substituted by Jerónimo Valdés y Sierra (1784–1855), Captain General of the Island of Cuba from 7 March 1841 to 13 September 1843.
