But in these views he was overruled by the war-party, whose animosity was sharpened, rather than subdued, by the late discomfiture. Their hostile feelings were further exasperated by the younger Xicotencatl, who burned for an opportunity to retrieve his disgrace, and to wipe away the stain which had fallen for the first time on the arms of the republic.
In their perplexity they called in the assistance of the priests, whose authority was frequently invoked in the deliberations of the American chiefs. The latter inquired, with some simplicity, of these interpreters of fate, whether the strangers were supernatural beings, or men of flesh and blood like themselves. The priests, after some consultation, are said to have made the strange answer that the Spaniards, though not gods, were children of the Sun, that they derived their strength from that luminary, and when his beams were withdrawn their powers would also fail. They recommended a night-attack, therefore, as one which afforded the best chance of success. This apparently childish response may have had in it more of cunning than credulity. It was not improbably suggested by Xicotencatl himself, or by the caciques in his interest, to reconcile the people to a measure which was contrary to the military usages—indeed, it may be said, to the public law—of Anahuac. Whether the fruit of artifice or superstition, it prevailed; and the Tlascalan general was empowered, at the head of a detachment of ten thousand warriors, to try the effect of an assault by night on the Christian camp.
The affair was conducted with such secrecy that it did not reach the ears of the Spaniards. But their general was not one who allowed himself, sleeping or waking, to be surprised on his post. Fortunately, the night appointed was illumined by the full beams of an autumnal moon; and one of the vedettes perceived by its light, at a considerable distance, a large body of Indians moving towards the Christian lines. He was not slow in giving the alarm to the garrison.
