"They come to their own destruction," said the monarch, bitterly, and immediately proceeded to distribute his men, to give them a fitting reception. The larger part of the forces were ordered to occupy several somewhat retired places, amid the great public buildings in the centre of the city, where they should be in readiness to obey the royal signal. The remainder were to go out, in their several divisions, to meet and skirmish with the advancing foe, doing them as much mischief as possible, yet suffering themselves to be driven before them, till they were decoyed into the heart of the city. The signal would then be given, when every man who could draw a bow, or wield a lance, or throw a stone, would be expected to do his duty. It was a stratagem worthy of Guatimozin, and, in its execution, had well nigh overwhelmed the Spaniards, and saved the city. Cortez had appointed with the captains of each division of his army to meet in the great square of the city. Each one being eager to be first at the goal, they followed the retreating Aztecs without consideration, and without making any provision for their own retreat. The watchful agents of Guatimozin were behind as well as before them; and when they had passed the gates, and were pressing up, with all the heat and enthusiasm of a victorious army, into the heart of the city, the bridges were taken up in their rear, to cut off, if possible, their retreat. When this was effected, the fatal horn of Guatimozin blew a long loud blast, from the summit of the great Teocalli. In an instant, the retreating Aztecs turned upon their pursuers, like tigers ravening upon their prey; while swarms of fresh warriors poured in from every lane and street and avenue, rushing so fiercely upon the too confident assailants, as to bring them to a sudden pause in their triumphant career. At the same moment, the roof of every house and temple, along the whole line of their march, was covered with men, who poured upon them such a shower of stones that it seemed impossible to escape being buried under them. The tide of battle was now turned. The too daring invaders were thrown into confusion, and compelled to retreat. This they soon found, to their bitter cost, was nearly impossible. When it was discovered that the bridges, over which they had so recently passed, were removed, the utmost consternation prevailed. The heavy cannon were all on board the brigantines, so that they were unable, as in former times, to mow down the solid ranks of their foes, and break a way for their retreat. Their cavalry was of little service, for they could not leap the wide chasms made by the removal of the bridges. Cut off in front by the solid masses of warriors that blocked up every avenue, and in the rear by these yawning chasms, and hemmed in on each side by the massive stone walls of the buildings, they could neither protect themselves, nor effectually annoy their enemy. They were in imminent danger of perishing ignobly in the ditch,
