CHAPTER XXVIII. INVALUABLE FRIENDSHIP. July-September , 1520.

A number of the besieged, outside the citadel, had already fled toward the Aztec camp, whose battalions were now descending, brilliant in feathered mail and ornaments. Entering the further side of the city they began to fire it. Cortés was summoned to the rescue, and hurrying onward with the cavalry he soon routed their disorganized masses, leaving pursuit chiefly to the allies. At a certain pass the enemy rallied, to be dislodged within a few moments and cut off from their camp. Exhausted by battle and flight, under a broiling sun, they turned in disorderly scramble up the steep mountain slope, only to find themselves checked on the summit by fleeter bands of Quauhquechollans and other allies, and obliged to make a stand. By this time they could hardly raise their hands in self-defence, and the battle became little more than a butchery, during which scattered remnants alone managed to escape, leaving the rich garments and jewels of the dead to stay the pursuers, who now, according to Cortés, numbered over one hundred thousand. Several Spaniards were wounded, and one horse killed.⁴⁰ The field being reaped, the victors entered the camp,⁴¹ which was divided into three parts, each large enough, it is said, to form a respectable town, well appointed, with hosts of servants, supplies, and paraphernalia. Laden with spoils they returned to the city to receive a well merited ovation. The citizens were afterward rewarded with several privileges for their loyal aid;⁴² deservedly rewarded, for without their coöperation the place could not have been captured without difficulty, since it lay between two rivers⁴³ coursing through deep ravines, and was shielded on one side by a steep mountain range. Beside its natural strength the city was protected by a breastwork of masonry, which extended toward the mountain and down into the ravines, forming here a smooth facing of some twenty feet, and rising in other places into a distinct wall of great height and width,⁴⁴ with a parapet. There were four entrances,⁴⁵ wide enough for one horseman only, with staircase approaches, and with maze-like lappings of the walls, which rendered it difficult to force an entrance. Along the walls lay piles of stones and rocks
