On their departure, the general summoned the Aztec ambassadors before him. He briefly acquainted them with his detection of the treacherous plot to destroy his army, the contrivance of which, he said, was imputed to their master, Montezuma. It grieved him much, he added, to find the emperor implicated in so nefarious a scheme, and that the Spaniards must now march as enemies against the prince whom they had hoped to visit as a friend. The ambassadors, with earnest protestations, asserted their entire ignorance of the conspiracy, and their belief that Montezuma was equally innocent of a crime which they charged wholly on the Cholulans. It was clearly the policy of Cortés to keep on good terms with the Indian monarch, to profit as long as possible by his good offices, and to avail himself of his fancied security--such feelings of security as the general could inspire him with--to cover his own future operations. He affected to give credit, therefore, to the assertion of the envoys, and declared his unwillingness to believe that a monarch who had rendered the Spaniards so many friendly offices would now consummate the whole by a deed of such unparalleled baseness. The discovery of their twofold duplicity, he added, sharpened his resentment against the Cholulans, on whom he would take such vengeance as should amply requite the injuries done both to Montezuma and the Spaniards. He then dismissed the ambassadors, taking care, notwithstanding this show of confidence, to place a strong guard over them, to prevent communication with the citizens.[208] That night was one of deep anxiety to the army. The ground they stood on seemed loosening beneath their feet, and any moment might be the one marked for their destruction. Their vigilant general took all possible precautions for their safety, increasing the number of the sentinels, and posting his guns in such a manner as to protect the approaches to the camp. His eyes, it may well be believed, did not close during the night. Indeed, every Spaniard lay down in his arms, and every horse stood saddled and bridled, ready for instant service. But no assault was meditated by the Indians, and the stillness of the hour was undisturbed except by the occasional sounds, heard in a populous city, even when buried in slumber, and by the hoarse cries of the priests from the turrets of the _teocallis_, proclaiming through their trumpets the watches of the night.[209] CHAPTER VII TERRIBLE MASSACRE--TRANQUILLITY RESTORED--REFLECTIONS ON THE MASSACRE--FURTHER PROCEEDINGS--ENVOYS FROM MONTEZUMA 1519
