CHAPTER VIII. 1521.

Tezcocans, and even the loyal Tlascalans, the hereditary enemies of the Montezumas and Guatemozins, stole off secretly under the cover of night. There were of course exceptions in this inglorious desertion; but it seems that perhaps the majority of the tribes departed for their homes with the belief that the tide had turned against the Spanish conqueror and that it was best to escape before it was too late, the scandal or danger of open treason against their lawful Emperor. But, amid all these disasters, the noble heart of Cortéz remained firm and true to his purpose. He placed his artillery again in position upon the causeways, and, never wasting his ammunition, contrived to husband it carefully until the assaulting Aztecs swarmed in such numbers on the dykes that his discharges mowed them down like grass as they advanced to attack him. It was a gloomy time, requiring vigilance by day and by night—by land and by water. The brigantines were still secure. They swept the lake continually and cut off supplies designed for the capital. The Spaniards hermetically sealed the causeways with their cannon, and thus, at length, was the city that would not yield to storm given over to starvation.
