The condition of the besieged was gloomy enough. True their provisions still held out, but they suffered greatly from want of water, that within the enclosure being quite brackish, until a fresh spring was suddenly discovered in the courtyard. Even then the fact that scarcely a man had escaped unwounded, and that they had no prospect before them but a lingering death by famine, or one more dreadful still upon the altar of sacrifice, made their situation a very trying one. The coming of their comrades was therefore doubly welcome. As an explanation of his atrocious act, Alvarado declared that he had but struck the blow to intimidate the natives and crush an intended rising of the people, of which he had received information through his spies. Cortes listened calmly till the story was finished, then exclaimed with undisguised displeasure, 'You have done badly. You have been false to your trust. Your conduct has been that of a madman!' And so saying, he turned and left him abruptly, no doubt bitterly regretting that he had entrusted so important a command to one whose frank and captivating exterior was but the mask for a rash and cruel nature. Vexed with his faithless lieutenant, and embarrassed by the disastrous consequences of his actions, Cortes for the first time lost his self-control, and allowed his disgust and irritation to be plainly seen. He treated Montezuma with haughty coldness, even speaking of him as 'this dog of a king' in the presence of his chiefs, and bidding them fiercely go tell their master and his people to open the markets, or he would do it for them to their cost. The chiefs retired in deep resentment at the insult, which they comprehended well enough from his look and gesture, and the message lost nothing of its effect in transmission. By the suggestion of Montezuma, Cortes now released his brother Cuitlahua, thinking he might allay the tumult and bring about a better state of things. But this failed utterly, for the prince, who was bold and ambitious, was bitterly incensed by the injuries he had received from the Spaniards. Moreover, he was the heir presumptive to the crown, and was welcomed by the people as a substitute for the captive Montezuma. So being an experienced warrior, he set himself to arrange a more efficient plan of operations against the Spaniards, and the effect was soon visible. Cortes, meanwhile, had so little doubt of his ability to quench the insurrection that he said as much in the letter that he wrote to the garrison of Villa Rica informing them of his safe arrival in the capital. But his messenger had not been gone half-an-hour before he returned breathless with terror, and covered with wounds, saying that the city was in arms, the drawbridges were raised, and the enemy would soon be upon them.
