Uvalde County, named for Spaniard Juan de Ugalde, is in Southwest Texas midway between San Antonio and the International Amistad Reservoir on the United States-Mexico border. On January 9, 1790, Juan de Ugalde, governor of Coahuila and commandant of the Provincias Internas, led 600 men to a decisive victory over the Apaches near the site of modern Utopia. Today, Uvalde County covers 1,588 square miles.
