Cortez dismissed the priests, telling them that he intended to leave the city the following morning, and requested that they would induce the principal nobles engaged in the plot to pay him a visit, at once. As soon as the priests had left, he summoned his principal officers, and disclosed to them the plot he had discovered. There was much difference of opinion between them. Some were in favor of returning at once to the friendly city of Tlascala. Others voted for still advancing, but by the northerly route their allies had recommended. But the majority agreed, with their general, that their only chance of safety was in taking a bold course; for that retreat would raise the whole country against them, and ensure their destruction. When the nobles arrived, Cortez rebuked them mildly for their altered conduct and for the failure of supplies; and said that the Spaniards would no longer be a burden upon the city, but would march out on the following morning; and requested that they would furnish a body of two thousand men, to transport his artillery and baggage. As this suited admirably the designs of the natives, they at once agreed to furnish the required force. Upon their leaving, Cortez had an interview with Montezuma's ambassadors, who had accompanied him from the coast, and told them that he was aware of the treacherous plot to destroy him and his army, and that he was grieved to find that this vile act of treachery was instigated by Montezuma. The ambassadors, astounded at what appeared to them the supernatural knowledge of Cortez, and terrified at the position in which they found themselves, made earnest protestations of their entire ignorance of the scheme; and declared that they were convinced that the emperor was wholly innocent of it, and that it was entirely the act of the Cholulans. Cortez pretended to believe them, as he was desirous, as long as possible, of keeping up a semblance of friendship with Montezuma; and declared that he was willing to believe that, after the friendly messages and gifts the emperor had sent, he could not be guilty of such baseness and treachery. His anger therefore would be directed chiefly against the Cholulans, who were guilty not only of foul treachery to himself, but of dishonoring the emperor's name by their conduct. As soon, however, as the ambassadors had retired, a strong guard was placed over them, to prevent them from communicating with the citizens. Every precaution was taken, in case the plans of the enemy should be altered, and an attack made during the night. The guns were placed so as to command the approaches. The horses were kept saddled, and ready for action. Strong guards were placed, and the troops lay down in their armor. Orders were dispatched, to the Tlascalans, to hold themselves ready to march into the city in the morning, and join the Spaniards.
