Cortez and the cavaliers with him were forced to plunge once more into the canal, not all of them this time escaping. Alvarado stood on the brink for a moment, uncertain what to do, death behind him and deadly peril before. He was a man of great strength and agility, and despair now gave him courage. Setting his long lance firmly on the wreck that strewed the bottom, he sprang vigorously forward and cleared the wide gap at a bound, a feat that filled all who saw it with amazement, the natives exclaiming, as they beheld the seemingly impossible leap, "This is truly the _Tonatiuh_,—the child of the Sun!" This name they had given Alvarado from his fair features and flaxen hair. How great the leap was no one has told us, though the name of "Alvarado’s leap" still clings to the spot. Thus ended the frightful _noche triste_, or "doleful night." Cortez led the remnant of his men off the causeway, a feeble, wounded, straggling few, faltering from weariness and loss of blood. Fortunately, the Aztecs, attracted by the rich spoil that strewed the ground, did not pursue, or it is doubtful if a man of the Spaniards, in their worn and wounded state, would have survived. How many perished in that night of dread no one knows. A probable estimate is about five hundred Spaniards and four thousand natives, nearly all the rear-guard having fallen. Of forty-six horses, half had been slain. The baggage, the guns, the ammunition, the muskets, and nearly all the treasure were gone. The only arms left the warriors were their swords and a few damaged cross-bows, while their mail was broken, their garments were tattered, their proud crests and banners gone, their bright arms soiled, and only a miserable and shattered fragment of their proud force was left, these dragging themselves along with pain and difficulty. [Illustration: AZTEC IDOLS CARVED IN STONE.] AZTEC IDOLS CARVED IN STONE. Day after day passed as the Spaniards and their allies, the Tlascalans,—inveterate enemies of the Aztecs,—slowly moved away from that blood-stained avenue of death, now little molested by their foes, and gradually recovering from their fatigue. On the seventh morning they reached the mountain height which overlooks the plain of Otumba, a point less than thirty miles from the capital. This plain they were obliged to traverse on their way to Tlascala, their chosen place of retreat. As they looked down on the broad level below them they saw with shrinking hearts why they had not been as yet molested. A mighty host filled the whole valley from side to side, their arms and standards glistening in the sun, their numbers so great that the stoutest heart among the Spaniards viewed them with dismay, and Cortez, daring and hopeful as he was, felt that his last hour had now surely come.
