Cortés had now been six days in Tacuba. There was nothing further to detain him, as he had accomplished the chief objects of his expedition. He had humbled several of the places which had been most active in their hostility; and he had revived the credit of the Castilian arms, which had been much tarnished by their former reverses in this quarter of the Valley. He had also made himself acquainted with the condition of the capital, which he found in a better posture of defence than he had imagined. All the ravages of the preceding year seemed to be repaired, and there was no evidence, even to his experienced eye, that the wasting hand of war had so lately swept over the land. The Aztec troops, which swarmed through the Valley, seemed to be well appointed, and showed an invincible spirit, as if prepared to resist to the last. It is true, they had been beaten in every encounter. In the open field they were no match for the Spaniards, whose cavalry they could never comprehend, and whose fire-arms easily penetrated the cotton mail which formed the stoutest defence of the Indian warrior. But, entangled in the long streets and narrow lanes of the metropolis, where every house was a citadel, the Spaniards, as experience had shown, would lose much of their superiority. With the Mexican emperor, confident in the strength of his preparations, the general saw there was no probability of effecting an accommodation. He saw, too, the necessity of the most careful preparations on his own part--indeed, that he must strain his resources to the utmost--before he could safely venture to rouse the lion in his lair. The Spaniards returned by the same route by which they had come. Their retreat was interpreted into a flight by the natives, who hung on the rear of the army, uttering vainglorious vaunts, and saluting the troops with showers of arrows, which did some mischief. Cortés resorted to one of their own stratagems to rid himself of this annoyance. He divided his cavalry into two or three small parties, and concealed them among some thick shrubbery which fringed both sides of the road. The rest of the army continued its march. The Mexicans followed, unsuspicious of the ambuscade, when the horse, suddenly darting from their place of concealment, threw the enemy’s flanks into confusion, and the retreating columns of infantry, facing about suddenly, commenced a brisk attack, which completed their consternation. It was a broad and level plain, over which the panic-struck Mexicans made the best of their way, without attempting resistance; while the cavalry, riding them down and piercing the fugitives with their lances, followed up the chase for several miles, in what Cortés calls a truly beautiful style.[352] The army experienced no further annoyance from the enemy.
