The Aztecs, indignant at the sacrilegious outrage perpetrated before their eyes, and gathering courage from the inspiration of the place, under the very presence of their deities, raised a yell of horror and vindictive fury, as, throwing themselves into something like order, they sprang, by a common impulse, on the Spaniards. The latter, who had halted near the entrance, though taken by surprise, made an effort to maintain their position at the gateway. But in vain; for the headlong rush of the assailants drove them at once into the square, where they were attacked by other bodies of Indians, pouring in from the neighboring streets. Broken, and losing their presence of mind, the troops made no attempt to rally, but, crossing the square, and abandoning the cannon, planted there, to the enemy, they hurried down the great street of Iztapalapan. Here they were soon mingled with the allies, who choked up the way, and who, catching the panic of the Spaniards, increased the confusion, while the eyes of the fugitives, blinded by the missiles that rained on them from the _azoteas_, were scarcely capable of distinguishing friend from foe. In vain Cortés endeavored to stay the torrent, and to restore order. His voice was drowned in the wild uproar, as he was swept away, like drift-wood, by the fury of the current. All seemed to be lost;--when suddenly sounds were heard in an adjoining street, like the distant tramp of horses galloping rapidly over the pavement. They drew nearer and nearer, and a body of cavalry soon emerged on the great square. Though but a handful in number,{*} they plunged boldly into the thick of the enemy. We have often had occasion to notice the superstitious dread entertained by the Indians of the horse and his rider. And, although the long residence of the cavalry in the capital had familiarized the natives in some measure with their presence, so long a time had now elapsed since they had beheld them that all their former mysterious terrors revived in full force; and, when thus suddenly assailed in flank by the formidable apparition, they were seized with a panic and fell into confusion. It soon spread to the leading files, and Cortés, perceiving his advantage, turned with the rapidity of lightning, and, at this time supported by his followers, succeeded in driving the enemy with some loss back into the enclosure. {*} [There were but three according to most accounts.--M.]
