By this time the advance guard was again heavily engaged. The Spaniards and their allies staggered along the dyke, fighting desperately all the time. Velasquez, leading the advance division was killed at the brink of the second opening. The wretched fugitives were driven headlong into the second opening which was soon choked with horses and men as the first had been. Over this living, dying bridge the survivors madly ploughed. Some of them led by Cortes himself found a ford on the side. Although they were cut down by the hundreds, there seemed to be no end to the Aztecs. The rain still fell. The drum of the war-god mingled with frightful peals of thunder, and the shrill cries of the Mexicans rose higher and higher. The Spaniards were sick, wounded, beaten and terrified. Only Cortes and his captains and a few of his veterans preserved the slightest semblance of organization.

The third gap was passed by the same awful expedient as the other two had been. There was not a great distance from the third opening to the mainland. The few who had passed over rushed desperately for the shore. Way back in the rear, last of all, came Alvarado. There was a strange current in the lake, and as he stood all alone at the last opening, confronting the pursuers, his horse having been killed under him, a swift movement of the water swept away the gorged mass of bodies. Torches in the canoes enabled the Aztecs to recognize Alvarado, Tonatiuh, the child of the sun. His helmet had been knocked off and his fair hair streamed over his shoulders. He indeed would be a prize for their sacrifice, second only to Cortes himself. With furious cries, the most reckless and intrepid leaped upon the dyke and rushed at him. At his feet lay his neglected lance. Dropping his sword, he seized his spear, swiftly plunged the point of it into the sand at the bottom of the pass, and, weighted though he was with his armor, and weak from his wounds and from the loss of blood, leaped to safety on the other side. To this day, this place of Alvarado's marvelous leap is pointed out. Like Ney, Alvarado was the last of that grand army, and like the French commander, also, he might properly be called the bravest of the brave.

Darkness was not the usual period for Aztec fighting. It was this alone that saved the lives of the remaining few for, having seen Alvarado stagger to freedom along the causeway, the Aztecs concluded that they had done enough and returned to the city rejoicing. They took back with them many Spaniards and Tlascalans as captives for sacrifice and the cannibalistic feast which followed.

When day broke, Cortes sitting under a tree, which is still to be seen in Mexico,[8] ordered the survivors to pass in review before him. They numbered five hundred Spaniards and two thousand Tlascalans and a score of horses. Seven hundred and fifty Spaniards had been killed or taken captive and four thousand Tlascalans. All the artillery had been lost, seven arquebuses had been saved, but there was no powder. Half the Spaniards were destitute of any weapons and the battle-axes and spears which had been saved were jagged and broken. Their armor was battered and the most important parts, as helmets, shields, breastplates, had been lost. Some of the Tlascalans still preserved their savage weapons. There was scarcely a man, Spanish or Tlascalan who was not suffering from some wound.

It is no wonder that when Cortes saw the melancholy and dejected array, even his heart of steel gave way and he buried his face in his hands and burst into tears. This terrible night has always been known in history as la noche triste—the melancholy night. Melancholy indeed it was. Surely the situation of a man was never more desperate. If the Mexicans had rejoiced in the leadership of a Cortes, they would have mustered their forces and fallen upon the Spaniards without the delay of a moment, and the result could only have been annihilation. But the Mexicans themselves had suffered terrifically. They had won a great victory, but they had paid a fearful price for it. Now they wanted to enjoy it. They wished to sacrifice their captives to their gods, and they thought that there was no hope for the Spaniards, and that they might overwhelm them at their leisure.

This is Sir Arthur Helps' vivid description of the awful retreat:

"A little before midnight the stealthy march began. The Spaniards succeeded in laying down the pontoon over the first bridge-way, and the vanguard with Sandoval passed over; Cortes and his men also passed over; but while the rest were passing, the Mexicans gave the alarm with loud shouts and blowing of horns. 'Tlaltelulco![9] Tlaltelulco!' they exclaimed, 'come out quickly with your canoes; the teules are going; cut them off at the bridges.' Almost immediately after this alarm, the lake was covered with canoes. It rained, and the misfortunes of the night commenced by two horses slipping from the pontoon into the water. Then, the Mexicans attacked the pontoon-bearers so furiously that it was impossible for them to raise it up again. In a very short time the water at that part was full of dead horses, Tlascalan men, Indian women, baggage, artillery, prisoners, and boxes (petacas) which, I suppose, supported the pontoon. On every side the most piteous cries were heard: 'Help me! I drown!' 'Rescue me! They are killing me!' Such vain demands were mingled with prayers to the Virgin Mary and to Saint James. Those that did get upon the bridge and on the causeway found hands of Mexicans ready to push them down again into the water.

"At the second bridge-way a single beam was found, which doubtless had been left for the convenience of the Mexicans themselves. This was useless for the horses, but Cortes diverging, found a shallow place where the water did not reach further than up to the saddle, and by that he and his horsemen passed (as Sandoval must have done before). He contrived, also to get his foot-soldiers safely to the mainland, though whether they swam or waded, whether they kept the line of the causeway, or diverged into the shallows, it is difficult to determine. Leaving the vanguard and his own division safe on shore, Cortes with a small body of horse and foot, returned to give what assistance he could to those who were left behind. All order was now lost, and the retreat was little else than a confused slaughter, although small bodies of the Spaniards still retained sufficient presence of mind to act together, rushing forward, clearing the space about them, making their way at each moment with loss of life, but still some few survivors getting onward. Few, indeed, of the rear-guard could have escaped. It is told as a wonder of Alvarado, that, coming to the last bridge, he made a leap, which has by many been deemed impossible, and cleared the vast aperture. When Cortes came up to him, he was found accompanied by only seven soldiers and eight Tlascalans, all covered with blood from their many wounds. They told Cortes that there was no use in going further back, that all who remained alive were there with him. Upon this the General turned; and the small and melancholy band of Spaniards pushed on to Tlacuba, Cortes protecting the rear. It is said that he sat down on a stone in the village called Popotla near Tlacuba, and wept; a rare occurrence, for he was not a man to waste any energy in weeping while aught remained to be done. The country was aroused against them, and they did not rest for the night till they had fortified themselves in a temple on a hill near Tlacuba, where afterward was built a church dedicated, very appropriately, to Our Lady of Refuge (à Nuestra Señora de los Remedios)."

There is an old story of a Roman general, who after a most terrific defeat, a defeat due largely to his own incompetency, not only escaped censure but was officially thanked by the senate, because he declared publicly that he did not despair of the republic. Of that same temper was Cortes.

Exhorting his men in the face of this awful peril which menaced them to conduct themselves as white men, as Spaniards, and as soldiers of the Cross, Cortes led his army toward Tlascala. Upon the position of that republic absolutely depended the future. It depends upon the way you look at the situation as to how you estimate the conduct of these dusky allies of the unfortunate conqueror. Had there been any national feeling among them, had their hatred of the Aztecs been less, they might have broken their agreements with the Spaniards and overwhelmed them, but the hatred of the Tlascalans did not permit them to look beyond the present day. They decided to maintain the alliance they had entered into with Cortes and welcomed him with open arms. They gave him a chance to recuperate, to get something to eat, and to dress the wounds of his men. All the Spaniards wanted was time to bring about the inevitable downfall of Mexico and the Mexicans.
