From Cortés, Second Letter, 151

Moctezuma, who was still a prisoner, (together with his son and many other persons of distinction, who had been secured at the beginning of operations,) now came forward and requested to be taken to the terrace of the garrison, that he might speak to the leaders of his people and induce them to discontinue the contest. I caused him to be taken up, and when he reached a battlement projecting from the fortress, and sought an opportunity to address the people who were fighting in that quarter, a stone thrown by some one of his own subjects struck him on the head with so much force that he died in three days after. I then gave his dead body to two Indians who were amongst the prisoners and taking it upon their shoulders, they bore it away to his people; what afterwards became of it I know not. The war, however, did not cease, but increased in violence and desperation every day.
