Encouraged by this state of things, the Spanish general thought it a favorable moment to press his negotiations with the capital. He availed himself of the presence of some noble Mexicans, taken in the late action with Sandoval, to send another message to their master. It was in substance a repetition of the first, with a renewed assurance that, if the city would return to its allegiance to the Spanish crown, the authority of Guatemozin should be confirmed and the persons and property of his subjects be respected. To this communication no reply was made. The young Indian emperor had a spirit as dauntless as that of Cortés himself. On his head descended the full effects of that vicious system of government bequeathed to him by his ancestors. But, as he saw his empire crumbling beneath him, he sought to uphold it by his own energy and resources. He anticipated the defection of some vassals by establishing garrisons within their walls. Others he conciliated by exempting them from tributes or greatly lightening their burdens, or by advancing them to posts of honor and authority in the state. He showed, at the same time, his implacable animosity towards the Christians by commanding that every one taken within his dominions should be straightway sent to the capital, where he was sacrificed, with all the barbarous ceremonies prescribed by the Aztec ritual.[333] While these occurrences were passing, Cortés received the welcome intelligence that the brigantines were completed and waiting to be transported to Tezcuco. He detached a body for the service, consisting of two hundred Spanish foot and fifteen horse, which he placed under the command of Sandoval. This cavalier had been rising daily in the estimation both of the general and of the army. Though one of the youngest officers in the service, he possessed a cool head and a ripe judgment, which fitted him for the most delicate and difficult undertakings. There were others, indeed, as Alvarado and Olid, for example, whose intrepidity made them equally competent to achieve a brilliant _coup-de-main_. But the courage of Alvarado was too often carried to temerity or perverted by passion; while Olid, dark and doubtful in his character, was not entirely to be trusted. Sandoval was a native of Medellin, the birthplace of Cortés himself. He was warmly attached to his commander, and had on all occasions proved himself worthy of his confidence. He was a man of few words, showing his worth rather by what he did than what he said. His honest, soldier-like deportment made him a favorite with the troops, and had its influence even on his enemies. He unfortunately died in the flower of his age. But he discovered talents and military skill which, had he lived to later life, would undoubtedly have placed his name on the roll with those of the greatest captains of his nation.
