Exhausted and wounded as they were, it required the toilsome journey of a week to reach the mountain summits which encircle the great valley of Mexico. As they approached the defiles of these mountains, parties of the enemy were seen here and there in increasing numbers. The natives shouted to them from a distance insults, defiance, and threats. Marina, who fortunately escaped the massacre of the _dismal night_, remarked that they often, in exultant tones, exclaimed, "Hurry along, robbers, hurry along; you will soon meet with the vengeance due to your crimes." The significance of this threat was soon made manifest. As the Spaniards were emerging from a narrow pass among the cliffs of the mountains, they came suddenly upon an extended plain. Here, to their amazement, they found an enormous army of the natives filling the whole expanse, and apparently cutting off all possibility of farther retreat. The sight was sufficient to appal the most dauntless heart. The whole plain, as far as the eye could extend, seemed as a living ocean of armed men, with its crested billows of banners, and gleaming spears, and helmets, and plumes. Even the heart of Cortez for a moment sank within him as his practiced eye told him that there were two hundred thousand warriors there in battle array, through whose serried ranks he must cut his bloody path or perish. To all the Spaniards it seemed certain that their last hour had now tolled; but each man resolved to sell his life as dearly as possible.
