Now the Aztecs fighting alone were face to face with their foes and the last struggle began. First the Spaniards cut the aqueduct which supplied the city with water from the springs at the royal house of Chapoltepec, whither I was taken on being brought to Mexico. Henceforth till the end of the siege, the only water that we found to drink was the brackish and muddy fluid furnished by the lake and wells sunk in the soil. Although it might be drunk after boiling to free it of the salt, it was unwholesome and filthy to the taste, breeding various painful sicknesses and fevers. It was on this day of the cutting of the aqueduct that Otomie bore me a son, our first-born. Already the hardships of the siege were so great and nourishing food so scarce, that had she been less strong, or had I possessed less skill in medicine, I think that she would have died. Still she recovered to my great thankfulness and joy, and though I am no clerk I baptized the boy into the Christian Church with my own hand, naming him Thomas after me. Now day by day and week by week the fighting went on with varying success, sometimes in the suburbs of the city, sometimes on the lake, and sometimes in the very streets. Time on time the Spaniards were driven back with loss, time on time they advanced again from their different camps. Once we captured sixty of them and more than a thousand of their allies. All these were sacrificed on the altar of Huitzel, and given over to be devoured by the Aztecs according to the beastlike custom which in Anahuac enjoined the eating of the bodies of those who were offered to the gods, not because the Indians love such meat but for a secret religious reason. In vain did I pray Guatemoc to forego this horror. “Is this a time for gentleness?” he answered fiercely. “I cannot save them from the altar, and I would not if I could. Let the dogs die according to the custom of the land, and to you, Teule my brother, I say presume not too far.” Alas! the heart of Guatemoc grew ever fiercer as the struggle wore on, and indeed it was little to be wondered at. This was the dreadful plan of Cortes: to destroy the city piecemeal as he advanced towards its heart, and it was carried out without mercy. So soon as the Spaniards got footing in a quarter, thousands of the Tlascalans were set to work to fire the houses and burn all in them alive. Before the siege was done Tenoctitlan, queen of the valley, was but a heap of blackened ruins. Cortes might have cried over Mexico with Isaiah the prophet: “Thy pomp is brought down to the grave, and the noise of thy viols: the worm is spread under thee and the worms cover thee. How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground which didst weaken the nations!”
