More than once had the Aztecs attempted to bring the little republic into subjection, but in vain. In one campaign Montezuma had lost a favorite, besides having his army defeated; and though a much more formidable invasion followed, "the bold mountaineers withdrew into the recesses of their hills, and coolly watching their opportunity, rushed like a torrent on the invaders, and drove them back with dreadful slaughter from their territories."

The Tlascalans had of course heard of the redoubtable Europeans and their advance upon Montezuma's kingdom, but not expecting any visit themselves, they were in doubt about the embassy sent by Cortés, and the council had not reached a decision when the arrival of Cortés was announced at the head of his cavalry. Attacked by a body of several thousand Indians, he sent back a horseman to make the infantry hurry up to his assistance. Two of the horses were killed, a loss seriously felt by Cortés; but when the main body had discharged a volley from their muskets and crossbows, so astounded were the Tlascalan Indians that they stopped fighting and withdrew from the field.

Next morning, after Cortés had given careful instruction to his army (now more than 3,000 in number, with his Indian auxiliaries), they had not marched far when they were met by two of the Zempoallans, who had been sent as ambassadors. They informed Cortés that, as captives, they had been reserved for the sacrificial stone, but had succeeded in breaking out of prison. They also said that forces were being collected from all quarters to meet the Spaniards.

At the first encounter, the Indians, after some spirited fighting, retreated in order to draw the Spanish army into a defile impracticable for artillery or cavalry. Pressing forward they found, on turning an abrupt corner of the glen, that an army of many thousands was drawn up in order, prepared to receive them. As they came into view, the Tlascalans set up a piercing war-cry, shrill and hideous, accompanied by the melancholy beat of a thousand drums. Cortés spurred on the cavalry to force a passage for the infantry, and kept exhorting his soldiers, while showing them an example of personal daring. "If we fail now," he cried, "the Cross of Christ can never be planted in this land. Forward, comrades! when was it ever known that a Castilian turned his back on a foe?"

With desperate efforts the soldiers forced a passage through the Indian columns, and then, as soon as the horse opened room for the movements of the gunners, the terrible "thunder and lightning" of the cannon did the rest. The havoc caused in their ranks, combined with the roar and the flash of gunpowder, and the mangled carcasses, filled the whole of the barbarian army with horror and consternation. Eight leaders of the Tlascalan army having fallen, the prince ordered a retreat.

The chief of the Tlascalans, Xicotencatl, was no ordinary leader. When Cortés wished to press on to the capital, he sent two envoys to the Tlascalan camp, but all that Xicotencatl deigned to reply was

that the Spaniards might pass on as soon as they chose to Tlascala, and when they reached it their flesh would be hewn from their bodies for sacrifice to the gods. If they preferred to remain in their own quarters, he would pay them a visit there the next day.

The envoys also told Cortés that the chief had now collected another very large army, five battalions of 10,000 men each. There was evidently a determination to try the fate of Tlascala by a pitched battle and exterminate the bold invaders.

The next day, September 5, 1519, was therefore a critical one in the annals of Cortés. He resolved to meet the Tlascalan chief in the field, after directing the foot-soldiers to use the point of their swords and not the edge; the horse to charge at half speed, directing their lances at the eyes of their enemies; the gunners and crossbowmen to support each other, some loading while others were discharging their pieces.

Before Cortés and his soldiers had marched a mile they saw the immense Tlascalan army stretched far and wide over a vast plain. Nothing could be more picturesque than the aspect of these Indian battalions, with the naked bodies of the common soldiers gaudily painted, the fantastic helmets of the chiefs bright with ornaments and precious stones, and the glowing panoplies of feather-work....
