Ixtlilxochitl fails not to adopt a number which speaks so well for the size of his province. Hist. Chich., 307; Relaciones, 416. ‘La zanja tenia mas de dos estados de hondura y otros tantos de anchura, y iba toda chapada y estacada.’ Cortés, Cartas, 206. Bustamante claims to have seen traces of it, Sahagun, Hist. Conq., 66-7, as did Lorenzana in his time. Cortés, Hist. N. Esp., 234. For the caulking of the vessels cotton was also used, and for want of grease, human fat was obtained from slain enemies, writes Gomara. Oidor Zuazo was assured of this pagan consecration for the fleet. This has been denied by others, observes Oviedo, iii. 423-4; but there is nothing improbable in a partial use thereof, for human fat had been frequently used in other cases, as Cortés admits. Additional timber was obtained in Tolantzinco, says Ixtlilxochitl.

CHAPTER XXXI.
PRELIMINARY CAMPAIGNS.
March-May, 1521.

Plan for the Investment of Mexico—Reconnoitring Tour round the Lake—Cortés in Command—Alvarado and Olid Accompany—They Proceed Northward from Tezcuco—Capture of Cities and Strongholds—Xaltocan, Quauhtitlan, Tenayocan, Azcapuzalco, Tlacopan, and back to Tezcuco—Chalco Disturbed—Peace Proposals Sent to Mexico—Further Reconnoissance of the Lake Region—Many Battles and Victories—Quauhnahuac Captured—Burning of Xochimilco—Second Return to Tezcuco—Conspiracy.

The arrival at Tezcuco of the brigantines recalled the necessity for planning the investment of Mexico, and this involved a reconnoitring tour round the lake, for which the Tlascaltecs in particular were importunate. Chichimecatl pressed this measure the moment he arrived at Tezcuco. He had come to serve the emperor, to join the Spaniards in avenging their fallen countrymen. Cortés expressed appreciation of his zeal, “but rest now,” he said, “for soon you shall have your hands full.” A few days later the general set out from Tezcuco with twenty-five horse, three hundred foot-soldiers, twenty-five archers and crossbowmen, and over thirty thousand allies, chiefly Tlascaltecs, with a number of Tezcucans. Among the war material were six field-pieces.[1062] Alvarado and Olid accompanied the expedition, and also a number of the Tezcucan leaders, partly as hostages, while Sandoval remained in charge. A northward course was taken, though the aim and destination were divulged to but a few, owing to the distrust still entertained of the Tezcucans.

The Valley of Mexico.

On the Tecama Plain, four miles from Tezcuco, a hostile force approached, probably by accident. After routing them the army encamped. The following day they proceeded to Xaltocan,[1063] a prominent town situated on an island in the northern end of the lake bearing that name. Once the capital successively of a Toltec, Otomí, and Chichimec principality, it had succumbed to the vicissitudes of political revolution and wars, and was at present one of the chief strongholds belonging to the tripartite power in the valley. It was approached by a causeway provided with breastworks and drawbridges.

The intention of the army had been surmised, so that preparations were made in every direction to resist an entry, and the water swarmed with canoes. In advancing along the causeway a tempest of stones, arrows, and darts came upon them from both sides, while hampered on a narrow road, hemmed in by the waters, and able to do little against the floating enemy, who were comparatively safe behind the bulwarks fitted to their canoes. Advance was soon stopped by the first trench in the causeway, not only wide and deep, but protected on the farther side by strong breastworks. The situation was embarrassing. Falling back a little, with the loss of one man, the guns were brought forward to protect the allies while filling the gap; but at this juncture two Tezcucans informed Cortés that they could guide him across by a fordable passage.

The offer was eagerly accepted, and while a part of the forces attracted the foe to the causeway, and the horses covered the rear, Cortés led another party by the ford. The water reached only to the waist, and though the enemy hastened forward, resistance was in vain, and soon the town was reached, and all who had not escaped immediately surrendered. Good spoils were secured of fabrics and other merchandise, as well as some gold. Since the canoe fleet might attempt a night attack, it was not considered safe to camp on the island, and as the army withdrew to the plain one league beyond, a part of the town was fired, in further warning. Xaltocan had more than once before risen from her ashes, but these were the flames of her funeral pyre. She never assumed importance again, and is now but a pretty village.

The next camp was formed in Quauhtitlan, “a large and beautiful city,” as Cortés calls it, which was found deserted. Thence they followed the route which had been taken after that night of ineffaceable horrors, when the foe seemed to fill the air and beat their faces in the blackness like the birds of Avernus, cutting off the stragglers faint with wounds and hunger, and sending terror to the hearts of the bravest. Now they came in confident strength, yet again the foe hovered round, though only at a distance, along the safe hill slopes, while from the summits rose pillars of smoke to proclaim the coming of the avengers. They passed through Tenayocan, once the capital of the Chichimec empire, and now renowned only for the immense serpent idols in its temple, from which the Spaniards called it El Pueblo de los Sierpes. Thence to Azcapuzalco, the former proud seat of the Tepanec kings.[1064]
