From the Annals of the Missionaries – In 1709, an expedition led by Franciscan fathers Antonio de San Buenaventura y Olivares and Isidro Félix de Espinosa reached the site of current day San Antonio. Olivares and Espinosa were escorted by Capt. Pedro de Aguirre and fourteen soldiers. The small expedition left San Juan Bautista on April 5 with the goal of contacting Tejas Indians living on the lower Colorado River. The Fathers encamped at site near the springs that they christened as San Pedro Springs. The expedition continued on and reached the Colorado near Bastrop on May 19. However, the Tejas were living further east and the Fathers did not have authorization to proceed farther than the Colorado. , They had also learned that the Tejas were likely hostile to the Spanish and the expedition returned to the Rio Grande.
