GUADALAJARA, DIEGO DE (?-?). In 1654 Diego de Guadalajara was placed by the viceroy, the Conde de Alba de Liste, in charge of an expedition to explore the Concho River country in Texas after Hernán MartÃn and Diego de Castilloqv returned with pearls from an expedition into that area. With thirty soldiers and some 200 friendly Indians, Guadalajara left Santa Fe and followed the route of the former expedition to the Concho. There the Jumano Indians informed him that the Indians in the territory beyond were at war and would not receive the Spaniards. A scouting party under Andrés López pushed seventy-five miles east of the Concho and was attacked by the Cuitao Indians. The Spaniards defeated the Indians, captured 200 of them and a large number of skins, and rejoined the main expedition in the vicinity of present-day San Angelo. They returned to Santa Fe because the expedition was not equipped to continue fighting.
