Once more, after disastrous retreats and heavy loss, the bleeding and discouraged Spaniards lay in their camp, as evening fell. Of dead, wounded, and captured the Spaniards missed more than a hundred and twenty of their comrades, and the Tlascalans a thousand, whilst valuable artillery, guns, and horses were lost. But listen! what is that mournful, penetrating sound which smites the Christians' ears? It is the war-god's drum, and even from where the Spaniards stand there is visible a procession ascending the steps of the _teocalli_, and, to their horror, the forms of their lost comrades are seen within it: whose hearts are doomed to be torn out living from their breasts to smoke before the shrine of Huitzilopochtli, the war-devil of their enemies. From that high and fearful place their comrades' eyes must be gazing with despairing look towards the impotent Spanish camp, glazing soon in death as the obsidian knives of the priests performed their fiendish work. The disastrous situation of the Spaniards was made worse by the desertion, at this juncture, of the Tlascalan and other allies. Awed by a prophecy sent out confidently by the Aztec priests, that both Christians and allies should be delivered into their hands before eight days had passed (prophecy or doom, which the priests said, was from the mouth of the war-god, appeased by the late victory), the superstitious Indians of Cortes's forces sneaked off in the night. Continued reverses, in the face of long-continued action and desire for the attaining a given end, forges in the finer calibre of mind a spirit of unremitting purpose. Blow after blow, which would turn away the ordinary individual from his endeavour, serves to steel the real hero to a dispassionate and persistent patience, and the purpose from its very intensity becomes almost a sacred cause, and seems to obtain from the unseen powers of circumstance success at last. So with Cortes and others of the Spaniards. The period prescribed by the somewhat rash prophecy of the Aztec priests and their infernal oracle having passed without anything remarkable having taken place, the Tlascalan and Texcocan allies, upbraided and warned by the Spaniards' messengers, now sneaked back to resume the attack against the city. The Aztecs had sought to cause disaffection in outlying places by sending round the bloody heads of decapitated Spaniards and horses, but with little effect. Cortes then prepared for a final effort. The plan adopted was to be slower but surer than the former one of simple slaughter. It was determined to raze the city to the ground; to destroy the buildings step by step, fill up the canals, and so lay waste the whole area from the outside, so that unobstructed advance might be maintained.
