In the mean time, Cortes had brought the fleet out on the lake, and after various manœuvres, proceeded to attack a rock near the city, where a large number of the inhabitants had fled for refuge. The Mexicans, perceiving his design, sent out their whole naval force (consisting of four thousand canoes) against his brigantines. Cortes now moved fairly out into the lake, and formed his fleet in the shape of a crescent to receive them. As they came near, the sails of the brigantines were spread, and they dashed through them, overturning some, and scattering the rest, to the great loss of the Mexicans. Olid had now reached his post, and from the temple at Cojohuacan saw the conflict on the lake. He instantly pushed along the causeway toward the city, drove the Mexicans from some of the trenches, and took possession. Cortes now attacked the bastion called Xoloc, situated at the angle made by the junction of the roads of Cojohuacan and Iztapalapan. The Mexicans defended the place with great obstinacy; multitudes fell in their efforts to save it, but it was stormed and taken. As this was a spot of great importance, and in direct communication with the division of Olid, Cortes determined to establish his camp here. The three divisions were now on the three causeways, and, as the principal attacks of the enemy were from the canoes that lined them, he distributed his fleet so as to protect the three divisions in their three efforts against the city—giving orders that they were to be managed in strict obedience to the three officers in command. The siege now regularly commenced.

From this moment, a series of attacks, retreats, skirmishes, and manœuvres, were going on upon the causeways. The causeway of Tacuba was the shortest, and it was supposed that Alvarado would be the first, therefore, to enter the city. But the fact that it was the shortest caused it to be the most carefully guarded. Every morning, Alvarado renewed his attempt, and each day met with a sharp opposition. At night, the Mexicans repaired whatever damage he had done, and in the morning showed themselves as stubborn as ever; while the Spaniards, regardless of wounds, endeavored to push their way onward to the capital, and were continually disappointed in their hope of reaching it. Alvarado perceived now, to his sorrow, that the destruction of the aqueduct of Chapoltepec had not taken from the city its supply of water. Canoes were seen continually by night bringing casks from the towns on the borders of the lake. Provisions were brought in the same way; thus defeating the hope of reducing the city by famine. Two of the brigantines were set to watch these boats and intercept them, but the cunning of the Mexicans defeated this. Their canoes were sailing in every direction, to beguile them. So far from being taken themselves, they even contrived to tempt the two brigantines near the border of the lake, where thirty of their largest boats lay in ambush. An attack was instantly made: the brigantines could not well be worked in that position; every Spaniard was wounded, and one of the captains killed. To increase the difficulty of the siege, periodical rains now set in; these, however, did not deter Alvarado and his followers from their attempts, though these attempts were still unsuccessful. Whatever advance he made, however, was a safe one; if he gained a foot of ground, he kept it. Houses were destroyed and ditches filled behind him as far as he passed, to enable him to make good his retreat, if it became necessary. Very much the same scenes were passing on the other causeways. Daily efforts were made, both by land and water, to force an entrance into the city, and all proved unsuccessful.

At last, wearied and mortified with continued disappointment, Cortes resolved upon a general assault. Accordingly, he commanded Alvarado and Sandoval to lead on their divisions, regardless of all opposition, while he himself took the command of the division at Cojohuacan. The order was instantly obeyed: the three divisions moved forward. The Mexicans met them with the fury of madmen; their opposition was tremendous. In spite of this opposition, however, Cortes continued to gain ground, carrying everything before him. Julian de Alderete, according to command that he should follow on and fill up all ditches behind him, was close upon him, but, in the ardor of the struggle, neglected this necessary duty. The Mexicans at length fled before Cortes, in apparent dismay, and he reached the capital. This was only a stratagem: the design was to bring him beyond the narrow pass in the causeway. He had no sooner entered the city, than the big drum was struck, the horns in the temple sent forth their blasts: the Mexicans raised their horrid yells, and at once flocked to the causeway. Alarmed for the safety of his men, Cortes ordered a retreat. Accordingly, they commenced retreating, but when they reached the narrow pass, all was confusion. Multitudes pressed upon them by land, arrows were showered upon them from the boats; it was now a general rout. Struggling to escape, the men pushed on only to plunge into the big ditch left open by Alderete. In that fatal gap fell men and horses, Spaniards and Indians, all in one mighty struggle. Cortes was still self-possessed; regardless of his life, he plunged into the gap, animating some, and rescuing others. Many a sinking companion did he save that day. In the midst of these noble struggles, he received a wound in the leg; six Mexicans seized him, and were carrying him off in triumph. At this critical moment, two brave Spaniards, Olea and Lerma, rushed to his rescue. Olea killed four of the Mexicans, and then lost his own life; while Lerma, sinking with his wounds, would likewise have been a captive, had not Quiñones, with a body of Spaniards and Tlascalans, at that instant snatched them from their danger. Cortes was lifted out of the water and placed upon a horse; the miserable remnant of his division escaping as it could.

Alvarado was hardly more successful. Having vanquished Cortes, the enemy now rushed upon him in greater numbers. To aid them, they cunningly threw into his ranks five bleeding heads, swearing that they were the heads of Cortes, Sandoval, and other chiefs, and that Alvarado’s should soon be added to the number. The Spaniards were in dismay; they supposed that their brave leader had perished, and could fight no longer. Alvarado ordered a hasty retreat, and with great difficulty escaped with a part of his division.

The division of Sandoval suffered the least loss. He had pressed far on toward the city, and felt sure of success, when suddenly numbers rushed upon him, both Cortes and Alvarado being defeated. The Mexicans resorted to the same stratagem that had been practised upon Alvarado. With desperate energy, however, he continued the fight, until, finding that there was no hope of success, he commenced retreating. By an effort of skill, he managed his retreat in so orderly a manner, that only two of his men were killed. The great mass, however (among them Sandoval himself), was wounded. In this general assault, which had thus ended, sixty Spaniards and a great number of allies were slain, while almost every survivor was suffering from his wounds. In addition to this, they lost six horses, one cannon, and a quantity of their arms.

Night now closed in, but not to give them rest. The Mexicans prepared for a frightful festival. The Spaniards heard the sound of the big drum, and the blasts of the horns and trumpets, mingled with the exulting yells of the conquerors, while in the temples, that were brilliantly illuminated, they saw the priests moving about, and their poor captive comrades made to dance naked before the idols. Then, too, they could hear the piercing shrieks of the wretched prisoners as they were laid upon the altars to be sacrificed; and while they spent the long night weeping for their friends, they vowed in their hearts an awful revenge.

After this defeat, the Mexicans sent the heads of those slain in sacrifice to all the neighboring towns and provinces, declaring to the people that the gods, being delighted with the blood of those sacrifices, had promised that in eight days the hated Spaniards should all be destroyed, and peace restored to their empire. This was a cunning stratagem. The superstition of the Indians allowed them to believe the story; and thus those provinces already hostile to the Spaniards, became more bitter in their hatred, while their allies began to desert. Even the Tlascalans were disposed to abandon him.[17] Cortes very prudently determined to attempt nothing during these eight days. He placed himself on the defensive, and resolved to wait quietly until the Indians should see that the story was idle.

Eight days passed away, and the Spaniards were still undestroyed. The Indians now flocked again to the standard of Cortes in larger numbers than ever; he soon had the command of fifty thousand allies. Just at this time, a vessel arrived at Villa Rica with men and ammunition. This last article was very much needed, as the Spaniards had spent nearly all their gunpowder. With a heart unbroken by his fresh calamity, and still carrying the fixed determination of conquering Mexico, Cortes now resolved upon another attack. This time he was resolved to trust to prudence as well as courage; and, giving up all thought of preserving the city, he at once commenced his siege of destruction.

The three divisions were commanded to advance in strict military order: they were to destroy every house in the way; while the allies, following immediately behind, were to fill up all ditches—thereby making a retreat easy, if necessary. The divisions started, and the plan was regularly followed up. Day after day the Mexicans found themselves shut up in narrower limits; yet Guatimozin continued his resistance, and seemed determined to see the last house in Mexico razed to the ground before he would consent that the Spaniards should enter the city. At length, Alvarado with his division worked his way to the great square of Tlalteloco. He found that a great number of warriors and priests had gathered in the temple which commanded the entrance to the square; and as his comrades from the other causeways were to meet in this square (the general mustering-place agreed upon), he determined to attack them. With his whole force, he rushed impetuously forward, gained the temple, drove out the Mexicans, set fire to the idols, and planted the Spanish banner on the top of the building, to cheer his approaching companions.

This was a joyous signal to Cortes and Sandoval. With renewed energies they pressed on, and in four days joined Alvarado in the square. His plan was thus far successful; he was now master of the western portion of the city, and Cortes resolved to pursue it further. Before doing this, however, he sent another messenger to Guatimozin with proposals. The proud Mexican King again gave him a scornful answer, and the Spaniards at once renewed their operations. Every day the Mexicans were enclosed in a narrower compass, while a heap of ruins continued to mark the progress of the Spaniards. The situation of the Mexicans was now awful. The brigantines commanded the lake, the Tlascalans cut off all communication by land; and thus the horrors of famine were added to those of war. The want of food soon produced disease among them, and now the awful horrors of war, famine, and pestilence, were all upon them. Every night the poor famishing creatures were prowling about the Spanish quarters in search of food; every day they were shut up in smaller limits. The heart of Guatimozin was touched, but not subdued; with a proud and unconquerable spirit, he seemed resolved to see his beautiful capital one complete ruin, rather than submit. All the city, except one small quarter, was now in possession of the Spaniards, and this was soon to share the fate of the rest.
