In a week after his arrival at his new quarters, Cortés, leaving the command of the garrison to Sandoval, marched against this Indian city, at the head of two hundred Spanish foot, eighteen horse, and between three and four thousand Tlascalans.
Their route lay along the eastern border of the lake, gemmed with many a bright town and hamlet, or, unlike its condition at the present day, darkened with overhanging groves of cypress and cedar, and occasionally opening a broad expanse to their view, with the Queen of the Valley rising gloriously from the waters, as if proudly conscious of her supremacy over the fair cities around her.
Farther on, the eye ranged along the dark line of causeway connecting Mexico with the main land, and suggesting many a bitter recollection to the Spaniards.
They quickened their step, and had advanced within two leagues of their point of destination, when they were encountered by a strong Aztec force drawn up to dispute their progress. Cortés instantly gave them battle. The barbarians showed their usual courage, but, after some hard fighting, were compelled to give way before the steady valor of the Spanish infantry, backed by the desperate fury of the Tlascalans, whom the sight of an Aztec seemed to inflame almost to madness. The enemy retreated in disorder, closely followed by the Spaniards. When they had arrived within half a league of Iztapalapan, they observed a number of canoes filled with Indians, who appeared to be laboring on the mole which hemmed in the waters of the salt lake. Swept along in the tide of pursuit, they gave little heed to it, but, following up the chase, entered pell-mell with the fugitives into the city.
The houses stood some of them on dry ground, some on piles in the water. The former were deserted by the inhabitants, most of whom had escaped in canoes across the lake, leaving, in their haste, their effects behind them.
