<P> In 1747 , the Spanish government sent José de Escandón to inspect the northern frontier of the North American colonies . Escandón assigned La Bahia 's captain , Joaquín Prudencio de Orobio y Basterra , to evaluate South Texas . On reading Orobio 's report , Escandón recommended that La Bahia be moved from its Guadalupe River location to the banks of the San Antonio River , so that it would be more capable of assisting settlements along the Rio Grande . Both the presidio and the mission likely moved in October 1749 . Escandón proposed that 25 Mexican families be relocated near the presidio to form a civilian settlement but was unable to find enough willing settlers . </P>
