The soldiers having now sacked the city, Cortés did not care to await further assaults from the enemy in his present quarters. On the fourth morning after his arrival, he mustered his forces on a neighboring plain. They came, many of them reeling under the weight of their plunder. The general saw this with uneasiness. They were to march, he said, through a populous country, all in arms to dispute their passage. To secure their safety, they should move as light and unencumbered as possible. The sight of so much spoil would sharpen the appetite of their enemies, and draw them on, like a flock of famished eagles after their prey. But his eloquence was lost on his men, who plainly told him they had a right to the fruit of their victories, and that what they had won with their swords they knew well enough how to defend with them. Seeing them thus bent on their purpose, the general did not care to balk their inclinations. He ordered the baggage to the centre, and placed a few of the cavalry over it; dividing the remainder between the front and rear, in which latter post, as that most exposed to attack, he also stationed his arquebusiers and crossbowmen. Thus prepared, he resumed his march, but first set fire to the combustible buildings of Xochimilco, in retaliation for the resistance he had met there.[381] The light of the burning city streamed high into the air, sending its ominous glare far and wide across the waters, and telling the inhabitants on their margin that the fatal strangers so long predicted by their oracles had descended like a consuming flame upon their borders.[382] Small bodies of the enemy were seen occasionally at a distance, but they did not venture to attack the army on its march, which, before noon, brought them to Cojohuacan, a large town about two leagues distant from Xochimilco. One could scarcely travel that distance in this populous quarter of the Valley without meeting with a place of considerable size, oftentimes the capital of what had formerly been an independent state. The inhabitants, members of different tribes, and speaking dialects somewhat different, belonged to the same great family of nations, who had come from the real or imaginary region of Aztlan, in the far Northwest. Gathered round the shores of their Alpine sea, these petty communities continued, after their incorporation with the Aztec monarchy, to maintain a spirit of rivalry in their intercourse with one another, which--as with the cities on the Mediterranean in the feudal ages--quickened their mental energies, and raised the Mexican Valley higher in the scale of civilization than most other quarters of Anahuac.
