The fickle people immediately returned to their stations, and others joined them, so that Cortez, according to his own account, now found himself at the head of one hundred and fifty thousand Indians. Gomara and Herrera assert that there were not less than two hundred thousand. The number of defenders in the Mexican capital can not with accuracy be ascertained. It is estimated, however, from various considerations, that there must have been at least two hundred thousand.

The Spaniards, in this sanguinary and protracted siege, often suffered severely for want of food. With apparent reluctance, the historians of the expedition record that their Indian auxiliaries found quite an abundant supply for themselves in the bodies of their enemies. Some of them were rather ashamed to acknowledge that their auxiliaries were inveterate cannibals. Cortez, however, alludes to their horrible repasts quite in a tone of indifference.

Progress of the siege.
The allies in the city.

With greater caution the Spaniards now advanced, fortifying every point they gained, and preparing a smooth and unobstructed road in their rear. Their progress was exceedingly slow, and it was necessary to adopt every possible precaution against an enemy who had manifested such unexpected audacity and skill. As the Spaniards pushed forward, the Mexicans, contesting every inch of the way, sullenly retired, rearing barricade after barricade, and digging ditch behind ditch. But artillery and European science were sure, in the end, to triumph. Gradually the three divisions of the army forced their way across the causeways, and entered the streets of the city. But here the defense was, if possible, still more determined and sanguinary. Every street was a guarded defile, where every obstacle was interposed which Mexican military skill could devise. Every house was a fortress, from whose battlemented roof and loop-holed windows a shower of stones, arrows, and javelins fell upon the besiegers. As the Spaniards gained ground, step by step, they leveled every house, and left entire ruin and desolation behind them.

Sufferings of the Mexicans.

Day after day and week after week of this unparalleled siege lingered along, every hour of which almost was a battle. The Mexicans fell in incredible numbers. The horrors of pestilence and famine in the pent-up city were soon added to the awful carnage and misery of war.

The brigantines swept the lake, cutting off nearly all supplies by water for the valiant yet starving defenders, while the armies on the causeways completely invested the city by land. Wan and haggard, these unhappy victims of European aggression, even when all hope of successful resistance had expired, heroically resolved to perish to the last man, and to bury themselves beneath the ruins of their city.

The public square.

Even the heart of Cortez was touched with the almost unearthly misery he was inflicting upon an unoffending people. Again and again he sent to Guatemozin demanding capitulation; but the proud Mexican monarch rejected every overture with indignation and scorn. At length the three divisions of the army, from their three different points of attack, penetrated the city so far as to meet at the great public square. The whole western portion of the city was now in the power of the besiegers. The starving and dying defenders were shut up in a small section of less than one fourth of the capital.
