At first the natives recoiled from the stern and fierce onset, rolling back till they left a wide lane for the passage of their foes. But they quickly rallied and poured on the little band in their midst, until it seemed lost in the overwhelming mass. A terrible fray followed, the Christians, as one writer says, standing "like an islet against which the breakers, roaring and surging, spend their fury in vain." The struggle was one of man to man, the Tlascalans and Spaniards alike fighting with obstinate courage, while the little band of horsemen charged deep into the enemy’s ranks, riding over them and cutting them down with thrust and blow, their onset giving fresh spirit to the infantry.
But that so small a force could cut their way through that enormous multitude of armed and valiant enemies seemed impossible. As the minutes lengthened into hours many of the Tlascalans and some of the Spaniards were slain, and not a man among them had escaped wounds. Cortez received a cut on the head, and his horse was hurt so badly that he was forced to dismount and exchange it for a strong animal from the baggage-train. The fight went on thus for several hours, the sun growing hotter as it rose in the sky, and the Christians, weak from their late wounds, gradually losing strength and spirit. The enemy pressed on in ever fresh numbers, forcing the horse back on the foot, and throwing the latter into some disorder. With every minute now the conflict grew more hopeless, and it seemed as if nothing were left but to sell their lives as dearly as possible.
At this critical juncture a happy chance changed the whole fortune of the day. Cortez, gazing with eagle eye around the field in search of some vision of hope, some promise of safety, saw at no great distance in the midst of the throng a splendidly dressed chief, who was borne in a rich litter and surrounded by a gayly attired body of young warriors. A head-dress of beautiful plumes, set in gold and gems, rose above him, and over this again was a short staff bearing a golden net, the standard of the Aztecs.
The instant Cortez beheld this person and his emblem his eye lighted with triumph. He knew him for the commander of the foe, and the golden net as its rallying standard. Turning to the cavaliers beside him, he pointed eagerly to the chief, exclaiming, "There is our mark! Follow me!" Then, shouting his war-cry, he spurred his steed into the thick of the foe. Sandoval, Alvarado, and others spurred furiously after him, while the enemy fell back before this sudden and fierce assault.
