in 1745, apache raiders from further north began looting and terrorizing spanish settlements through the entire allende valley. they attacked the town of san francisco de conchos on march 25, when they killed the franciscan missionary friars tomás de zigarán and francisco de labado who served the mission. they also burned the church and the friars' house. the apaches then immediately attacked the town of san pedro de conchos; there, the missionary left before befalling any harm and took refuge with the jesuits in satevó. from valle de allende, the friars and spanish residents were evacuated to villa lópez before the raiders arrived; but they were unable to prevent the apache from burning the convent and the sanctuary.
