Includes two informes in which gobernador describes to virrey chronological unfolding of Series of attacks by Aracates, Mesquites, others, on rancherias and villages of Sierra; number and location of Indians, 'pobladores,' soldiers killed given, as well as numbers of mules, horses stolen; 150 soldiers and 15 Indian auxiliaries to scour Sierra 'hasta no dejar indio en ella'; battles continue; 'piquete' of 15 soldiers captures 4 Indian men, Indian woman, child, who claim to be peaceful, escape after led to Soto la Marina; days earlier 2 unarmed 'vaqueros' killed, horses taken. In second letter, gobernador mountain pass in order to block Indians' retreat; plan somewhat effective, as more Indians killed, 'collera' of 38 taken to San Luis Potosi; supposedly peaceful Mesquites and mulatos apparently responsible for the large and Volatile Indian gathering in Sierra, also for death of pastor and several horse thefts. With Indians run out of Sierra, gobernador feels time right to begin construction of road into area. Argues also that some villages repeatedly attacked by Apaches because residents do not know how to respond or defend selves; solution lies in uniting 'pobladores', teaching them how to protect family and possessions, then fighting 'con Teson.'
