Before leaving the camp, I had ordered that Gonzalo de Sandoval should proceed with the brigantines [ships] to the place where the Indians had fortified themselves in houses, thus holding them surrounded, but not attacking them until he should observe that we began to fight; in such manner that, holding them thus surrounded, they had no place to go except amongst the dead, and on the roofs which were left them. For this cause, they neither had, nor procured [obtained], arrows, nor darts, nor stones, with which to hurt us. Our friends accompanied us, armed with swords and shields, and such was the slaughter done that day on water and on land, that with prisoners taken they numbered in all more than forty thousand men; and such were the shrieks and the weeping of the women and children that there was none whose heart did not break; and we had more trouble in preventing our allies from killing and inflicting tortures than we had in fighting with the Indians, for no such inhuman cruelty as the natives of these parts practice was ever seen amongst any people. Our allies obtained very great plunder, which we could not prevent, because we were about nine hundred Spaniards, and they more than one hundred and fifty thousand men, and no attention or diligence [carefulness] was sufficient to prevent them from robbing, although we did everything possible to stop it. One of the reasons why I refused to go to extremes in those previous days was that, by taking them by assault [force], they would probably throw what they had into the lake, and if they did not do so our allies would steal everything they found; and, for this reason, I feared that but a small part of the great wealth existing in the city, as shown by what I had before obtained for Your Highness, would be secured for Your Majesty. As it was already late, and we could no longer endure [stand] the stench of the dead which had lain for many days in those streets (the most pestilential [plague-like] thing in the world), we returned to our camps. [...]
When day had dawned, I had our whole force prepared, and the large field pieces brought out; and I had, the day before, ordered Pedro de Alvarado to await me in the square of the market-place, and not to begin fighting until I arrived. All being assembled, and the brigantines ready for action, behind the houses on the water, where the enemy were gathered, I ordered that, on hearing a musket-shot, the land force should enter the small part which was still to be captured, and force the enemy towards the water where the brigantines would be awaiting them; and I cautioned them particularly to look after Quatamucin [Cuauhtemoc, the Aztec emperor], and to endeavour [try] to take him alive, because then the war would stop. [...] After a short time, they returned with one of the highest chiefs of all of them, who was called Ciguacoacin, captain and governor of them all, whose counsel followed in everything concerning the war. I showed a very good disposition [mood] towards him, so that he might be reassured and have no fears, and finally he told me that the sovereign [king/ruler] would in no way appear before me, and that he rather preferred to die where he was, and that he himself was much grieved [pained] at this decision but that I could do as I pleased. Recognising by this his determination, I told him to return to his own people, and that he and they might prepare themselves, as I was determined to attack them, and finish destroying them; and so it happened. More than five hours had passed in these parleyings [discussions], and the inhabitants of the city were all treading [walking] on the dead, others in the water were swimming, and others drowning themselves in the large lake where the canoes were collected. Such was the plight [trouble] in which they were, that no understanding could conceive [imagine] how they could endure [bear] it; and an infinite number of men, women, and children kept coming towards us, who, in their haste [hurry], pushed one another back into the water and were drowned amidst the multitude [great number] of dead. It appears they had perished [died] to the number of more than fifty thousand, from the saltwater which they drank, or from starvation, and pestilence. [...] thus, in the streets they occupied, were found heaps of dead, so that nobody could step without trampling them. As the people of the city came towards us, I ordered Spaniards to be stationed in all the streets, to prevent our allies from killing those unhappy creatures, who were beyond number; and I also ordered the captains of our allies not to allow in any way those fugitives [escapees] to be killed, but, as they were so many, it was not possible to prevent it that day, so more than fifteen thousand persons were massacred. [...]
It pleased God that the captain of a brigantine, called García Holguín, overtook a canoe in which there were some distinguished people, and, as he had two or three cross-bowmen in the prow [front] of the brigantine, and was crossing in front of the canoe, they signaled to him not to shoot because their sovereign was there. The canoe was quickly captured, and they took Quatamucin, and the lord of Tacuba, and the other chiefs who were with him; and the said captain, García Holguín, immediately brought the said sovereign of the city and the other chief prisoners to the terrace where I was [...] he approached me and said to me in his language that he had done all that on his part he was bound to do to defend himself and his people, until he was reduced to that state, and that I might now do with him as I chose; and placing his hand on a dagger [sword] which I wore he bade [asked] me stab him with it and kill him. I encouraged him, and told him not to be afraid; and this lord having been made prisoner, the war immediately ceased [stopped], which God Our Lord was pleased to bring to its end on this day [...] which was the 13th of August in the year 1521. So that from the day when we laid the siege to the city, which was the 30th of May of the said year, until it was taken, seventy-five days passed, in which Your Majesty may perceive the hardships, dangers, and cruelties, which these, your vassals [subjects], suffered, and in which they so exposed themselves that their deeds will bear testimony of them. In all these seventy-five days of the siege, none passed without more or less fighting.
