The opening was widening every moment. No time was to be lost. The recall was sounded, but with the people so scattered it took some time to gather them. Staggering under the weight of spoil they fell into line, their march being dimly lighted by the flames behind them. The flood increased so much that few of them could retain their burdens, and near the opening the water came with such force as to make the passage difficult. Several of the allies were swept away. It was nine o’clock before the last of the troops gained the high land beyond the dike. “A delay of three hours longer, and none of us would have escaped,” writes Cortés. Failing in their desperate sacrifice to catch the invaders in the flooded houses, there to be imprisoned all night by the rushing waters, the enemy were at hand in canoes with early dawn, showering missiles and sallying against the flanks of the invaders. The Spaniards could only reply with sword and lance, for the powder was wet, and since nothing more could be done under the circumstances, they continued the retreat to Tezcuco. A number of allies fell, and even the soldiers, who had suffered no casualties in the capture of Iztapalapan, now lost one out of their ranks.[1047]

Notwithstanding the loss of booty and the humiliating retreat, the expedition had succeeded in its main object, to inflict a severe lesson on the foe by desolating one of the finest cities in the valley, at the very threshold of the capital. The effect was noticed in the arrival, the day after the return to Tezcuco, of messengers from Otumba and several adjacent towns,[1048] penitently to renew their allegiance, which was never again broken. A number of other towns and domains followed the example, notably Chalco, a large and fertile district extending round Chalco Lake, and toward the south-eastward. It had fallen from the rank of an independent kingdom to that of a province tributary to the Aztecs. The severity of its taskmasters kept ever smouldering the flame of revolt, and deeply the people sighed for deliverance. Owing to the proximity of the Mexicans and the presence of their lawless garrisons, they like many others had not before ventured to cast off the yoke, but with the approach of the Spaniards they gathered courage, and two envoys were sent to implore protection.[1049]

This accorded with Cortés’ plans, and Sandoval was instructed to assist them. His first order, however, was to escort to Tlascala with twenty horsemen and two hundred infantry the carriers, together with a number of warriors, who desired to return home with the booty so far acquired. Fresh supplies were likewise desired, and communication with Villa Rica must be kept open. They had not proceeded far before the Tlascaltecs, who had hastened in advance of the Spanish main body, found themselves attacked by a large force, which slew a number and captured the carriers’ train. Sandoval routed the assailants and recaptured most of the booty.[1050]

From Tlascala Sandoval turned to Chalco. In certain maizefields in front of the capital the Mexicans stood prepared with twelve thousand warriors to dispute possession. He charged them at the head of his cavalry, but, though yielding for a moment, they rallied and with their long pikes compelled him to fall back upon the infantry and allies. The second charge was more successful, and within two hours the foe was in flight, during which large numbers were slaughtered and some captives taken, including three leading men, while but few of the Spaniards were even wounded.

The Chalcans came forth to tender an ovation, and the two young rulers Acazitzin and Omacatzin[1051] accompanied the troops to personally offer allegiance to Cortés, together with some small presents. Their father had always admired the Spaniards and sought to serve them,[1052] and on his death-bed, during the late small-pox epidemic, he had recommended them and their counsellors to submit to the white chief, for to him and his children of the sun did prophecy point as rulers of that land. So important an accession gave no little pleasure to Cortés, who treated the young prisoners with every consideration. At their own request he confirmed them in the lordship, assigning to the eldest Chalco city, with more than half the towns in the province, while the younger received Tlalmanalco and Chimalhuacan, with Ayotzinco and other places subject to them.[1053]

The eight captives were kindly treated, and sent to Mexico with peace proposals similar to those transmitted by the former captors; but there came no reply. The secession of Chalco was a blow to the Mexicans even more severe than the capture of Iztapalapan, owing to the bad example to submissive and wavering provinces, and Quauhtemotzin hastened with allurements and threats to reimpress upon them the necessity for remaining true to the empire. These messages were also sent to the towns round Tezcuco; and the caciques of Coatlichan and Huexotla came to the Spanish camp in great distress, to say that all Mexico was coming upon them. They were doubtful whether to flee to the mountains or come to Tezcuco. They were reassured and promised succor when required; meanwhile they must entrench themselves and prepare the warriors. The Mexicans did little, however, beyond making raids on farms and stragglers from two towns,[1054] wherein they were entrenched, not far from Tezcuco. This attack on the larder of the army could not be endured, and Cortés went forth on two occasions to secure the threatened crops for himself, driving off a force of marauders who had come with quite a fleet in the expectation of a fine harvest, and capturing their strongholds on the lake.[1055]

All this made communication with Tlascala insecure, and on last leaving that province Sandoval had strictly forbidden any one to cross to Tezcuco without a permit. It so happened that a vessel arrived at Villa Rica with over thirty soldiers, besides the crew, eight horses, and a quantity of war stores. Knowing how pleased Cortés would be, a young soldier broke the rules, adventured his life, and carried the tidings to the general, who freely forgave the disobedience of orders. This young cavalier also reported that the brigantines were completed and ready for transport. Since siege operations could not begin until the brigantines were floated on Tezcuco Lake, no time was to be lost, and Sandoval received orders to proceed at once to Tlascala and convoy the precious train. In going he must pass through Zoltepec, five leagues distant, near the eastern border of Acolhuacan, and there inflict chastisement for the murder of the Yuste party during the late uprising.

Sandoval set out with fifteen horse and two hundred foot. On the way a house was passed bearing upon its wall the touching inscription, “Herein the unhappy Juan Yuste was a prisoner.” The inhabitants of Zoltepec, henceforth termed ‘pueblo Morisco,’ had long expected this descent, and no sooner did the party appear in sight than they hastened to the mountains. One body of soldiers entered the town to plunder, and found among other things relics of the dress, arms, and accoutrements of their slain comrades in one of the temples.[1056] Another body pursued the fugitives, killing a few and capturing a large number, chiefly women, who were enslaved. Their pleading so moved the heart of Sandoval that he issued a pardon to those who had escaped.

Meanwhile Martin Lopez, the master shipwright in Tlascala, had arranged for the transportation of the brigantines. A trial launch had been made of one or two above a dam thrown across Zahuatl River,[1057] and this proving satisfactory they were broken up. Upon the shoulders of eight thousand carriers were now loaded the separate pieces of timber and planks, duly marked and numbered for fitting them together; also the spars, cordage, sails, together with a quantity of ammunition, two heavy guns, and other effects.[1058] Gayly they bent to the burden wherein lay enginery so portentous for the destruction of the hated Aztecs. The caravan set forth, escorted by a large force of warriors, and halted at Hueyotlipan to await the Spanish convoy. After a time the Tlascaltecs became impatient, and regardless of warnings proceeded. While encamped near the border an alarm was raised, and tumultuously the warriors rushed to arms to protect a portion at least of the train which had cost such labor and embodied such hopes. The next moment a cheer was heard. It was Sandoval and his men.

With this new protection many of the Tlascaltec escort could be dismissed, and the remaining twenty thousand were redistributed, the rear being assigned to the leading chief, Chichimecatl, and the flanks to Axotecatl and Teotepil.[1059]
