Cortez asked him a few questions, and when he left the room said to Marina:
"That young fellow must be watched, Marina. He has been brought up with these people, and must to some extent feel with them. I know that he is a friend of yours, but see that you say nothing to him on public affairs. Let him be kept wholly in the dark, as to our plans and intentions. This Cacama is, next to Montezuma, the most powerful and important of the Aztec chiefs. He is young and energetic, and although he has been so badly treated by Montezuma, he resents our treatment of him. Had it been otherwise he would probably, ere this, have made some propositions to us, through Sancho, for a closer alliance with us, on the understanding that the territories Montezuma has taken from him shall be returned.
"We must have Cacama's actions closely watched. There are other Aztecs who are willing enough to act as our spies, and who will keep us informed of what is going on. Hitherto their reports have agreed with Sancho's, but from his sending the young fellow back here, Cacama may now be intending to act against us."
Cacama, indeed, lost no time in setting to work, and began to form a league with many of the leading nobles, to rescue the emperor and destroy the Spaniards. Montezuma's brother Cuitlahua and many others agreed, at once, to join him; but the greater part of the Aztec nobles hung back, upon the ground that they did not like to move in the matter, without the orders of their emperor. Their refusal prevented any general rising taking place, and thus destroyed the last chance of Mexico retaining its independence.
Cortez learned from his spies what was going on, and would have marched against Tezcuco, had not Montezuma dissuaded him; telling him that Cacama was a powerful prince, and would certainly be aided by many other chiefs, and that the enterprise would be hazardous in the extreme. Cortez then endeavored to negotiate, but received a haughty answer from Cacama. He then tried threats, asserting the supremacy of the Spanish emperor.
Cacama replied "that he acknowledged no such authority, he knew nothing of the Spanish sovereign or his people, nor did he wish to know anything of them."
Cortez then invited Cacama to come to Mexico to discuss their differences; but Cacama had no faith in Spanish loyalty, and he replied "that when he did visit the capital, it would be to rescue it, as well as the emperor himself, and their common gods, from bondage. He should come, not with his hand upon his breast but on his sword, to drive out the Spaniards, who had brought such disgrace upon the country."
While this had been going on, Montezuma had still further forfeited all claim to sympathy, by the willingness with which he accepted the attentions of those who were, in fact, his gaolers. They paid him all the outward marks of respect, pretending still to regard him as a powerful sovereign; and he, in return, was present at their exercises and sports, took the greatest interest in two ships they were building for navigation on the lake, and in all respects behaved to them as if they were his best friends. He now carried his baseness still further, and informed Cortez that several of the Tezcucan nobles were regularly in his pay, and that it would be easy, through them, to capture Cacama and thus break up the confederacy.
Cortez at once took means to carry out the suggestion. The traitors invited Cacama to a conference, at a house overhanging the lake near Tezcuco. Upon going there he was seized by them, bound, placed in a boat, and carried to Mexico. He was there brought before Montezuma.
In spite of the perils of his position, Cacama bore himself nobly. He boldly accused his uncle of foul treachery, and with the cowardice which he had betrayed since the Spaniards had entered his kingdom. Montezuma handed him over to Cortez, who ordered him to be loaded with fetters and thrown into a dungeon. The emperor then issued an order, declaring that Cacama had forfeited his sovereignty by his rebellion, and that he therefore deposed him, and appointed a younger brother named Cuicuitzca in his place. The other leaders of the confederacy were all seized by the orders of Montezuma in their own cities, and brought in chains to the capital, where they were imprisoned with Cacama.
