After I sent my last letter to your reverence by the maese de campo, Pedro de Leiva, while the necessary things were being made ready alike for the escort and in the way of provisions, for the most expeditious dispatch of the returning wagons and their guards, as your reverence had enjoined me, I received information that a plot for a general uprising of the Christian Indians was being formed and was spreading rapidly. This was wholly contrary to the existing peace and tranquillity in this miserable kingdom, not only among the Spaniards and natives, but even on the part of the heathen enemy, for it had been a long time since they had done us any considerable damage. It was my misfortune that I learned of it on the eve of the day set for the beginning of the said uprising, and though I immediately, at that instant, notified the lieutenant general on the lower river and all the other alcaldes mayores-so that they could take every care and precaution against whatever might occur, and so that they could make every effort to guard and protect the religious ministers and the temples-the cunning and cleverness of the rebels were such, and so great, that my efforts were of little avail. To this was added a certain degree of negligence by reason of the report of the uprising not having been given entire credence, as is apparent from the ease with which they captured and killed both those who were escorting some of the religious, as well as some citizens in their houses, and, particularly, in the efforts that they made to prevent my orders to the lieutenant general passing through. This was the place where most of the forces of the kingdom were, and from which I could expect some help, but of three orders which I sent to the said lieutenant general, not one reached his hands. The first messenger was killed and the others did not pass beyond Santo Domingo, because of their having encountered on the road the certain notice of the deaths of the religious who were in that convent, and of the alcalde mayor, some other guards, and six more Spaniards whom they captured on that road. Added to this is the situation of this kingdom which, as your reverence is aware, makes it so easy for the said [Indian] rebels to carry out their evil designs, for it is entirely composed of estancias, quite distant from one another.

On the eve of the day of the glorious San Lorenzo, having received notice of the said rebellion from the governors of Pecos and Tanos, who said that two Indians had left the Teguas, and particularly the pueblos of Tesuque, to which they belonged, to notify them to come and join the revolt, and that they [the governors] came to tell me of it and of how they were unwilling to participate in such wickedness and treason, saying that they now regarded the Spaniards as their brothers, I thanked them for their kindness in giving the notice and told them to go to their pueblos and remain quiet.
