Fearing the presence of the French in San Bernardo and Espíritu Santo, Portocarrero accelerated the pacification of the province of Nueva Extremadura de Coahuila and named Captain Alonso de León governor. On August 12, 1689, de León founded the city of Santiago de la Monclova, named for the viceroy. One hundred fifty families were established there, including 270 well-armed men to repulse any incursions of the French. The viceroy also ordered the repair or construction of other forts farther north, all in communication with each other.
