Three or four days later, another event occurred which heightened the fury of the Mexicans against the Spaniards. The cazique who had attacked the Spaniards on the coast arrived at Mexico, accompanied by his son and fifteen other chiefs who had acted with them. Montezuma referred the matter to the examination of Cortez. The cazique admitted the part he had taken in the attack on the Spaniards, and did not seek to shelter himself under royal authority; until sentence of death was passed on him and the other chiefs, when they all declared that they had acted on the authority of Montezuma. They were condemned to be burnt alive, in the space in front of the palace, and this sentence was carried out. Not content with this, Cortez placed irons upon Montezuma himself, saying there could now be no longer a doubt as to his guilt. After the execution was carried out, Montezuma was released from his fetters. The news of this insult to their monarch created a profound impression upon the Mexicans. Although they despised the weakness of a sovereign who appeared ready to suffer every indignity, and yet to claim an appearance of courtesy and goodwill towards his oppressors, the bolder spirits determined that the nation should be no longer humiliated in the person of its sovereign, and that even should it cost Montezuma his life, an effort should be made to overthrow his oppressors. As soon as the news of the execution of the seventeen nobles, and of the indignity to Montezuma was received; Cacama said to Roger: "My friend, I can no longer retain you here. You have told me why you cannot have it proclaimed that you are of different blood to the Spaniards, and I quite understand your motives; but there are two reasons why, in that case, you must for a time return to the capital. My people would look upon me with scorn, did I retain here as my friend one whom they regard as the countryman of the men who have so outraged us. Moreover, you yourself cannot wish to stay. You have told me that Cortez has charged you to acquaint him with the state of feeling in this city; and were you to remain here, you would be placed in the painful position of either giving information which would ruin my plans, or of deceiving the man whom you nominally serve. I know that you would say nothing against me, but should I fail and the Spaniards triumph, Cortez would accuse you of being a traitor, and you would be put to death by him. "Therefore, I think it in all ways best that you should return there, for the present. You will, of course, inform Cortez that I have sent you back because the feeling against the white men, on account of their treatment of the emperor, is so great that I felt that I could not protect you against their fury."
