Jack and Riconada hastened to obey these orders and blockaded the three bridges. Scarcely had they established themselves when the serpent-skin drums on the summit of the teocalli began to roll out the alarm. Frantic with rage and astonishment, the worshippers streamed towards the three bridges so as to repel the daring foes. No one could understand how these invaders had entered the city, and Ixtlilxochitli smitten with fear, called on the children of Huitzilopochtli to defend their god. The crowd pouring towards the bridges were driven back by the soldiers, and as they were without weapons, owing to having gone to the square for sacrifical purposes, they could do nothing. Ixtlilxochitli was equal to the occasion, and from some secret store produced shields and spears, bows and arrows, and swords of obsidian. The drums rolled, the trumpets shrilled, and the priests on the platform of the teocalli frantically invoked the god, while those whom they had aroused desperately attempted to force the bridges.

A feeling of superstitious terror was in the breasts of the Indians. These terrible white men, whom no obstacle seemed to hinder, had entered Totatzine as though by magic. How they had evaded the spies and overcome the difficulties of the secret way none knew, much less how they had discovered the passage. No one thought of the cañon road, not even Ixtlilxochitli, who never dreamed of danger from that quarter. All the inhabitants of Totatzine knew was that their worst foes were in the heart of their sacred city, and that, unless they drove them forth at once, the Shrine of the Opal would be lost for ever.

Flights of arrows fell round the soldiers holding the three bridges, and many were killed, as they had no shields with which to protect themselves. On the other hand, the round bucklers held up by the savages were no hindrance to the bullets of the invaders, and as the soldiers kept up a steady fire into the dense mass of worshippers, the ground was soon cumbered with the dead and dying.

Jack in vain looked for Xuarez, but could see no sign of him. On the summit of the teocalli he saw a vast crowd of priests crying on the war-god to defend his shrine, and thought for a moment, as the black mass parted, that a man was lying on the stone of sacrifice. But the next instant the throng closed together again, and he was forced to give his attention to the task of defending the causeway. His soul revolted against this butchery, and he ordered his soldiers to deal as gently as possible with the comparatively defenceless enemy. Nevertheless, he knew that the safety of himself and his friends depended on keeping the Indians blockaded until the reinforcements arrived, and was forced to massacre the crowds which hurled themselves with fanatical devotion against his men.

Owing to the depth of the torrent, there was no way of crossing it save by the bridges, and these being held by the invaders, it was impossible for the Indians to fight to any advantage. Wave after wave rolled across the narrow bridges, and midway were repelled by the incessant fire of the Tlatonacians. The spears and arrows of the Indians did deadly work, and the centre of the causeways were soon filled with corpses, white men and red men mingled promiscuously together. Jack saw plainly that the three bridges could be held by them for hours, yet wished from his soul that Martez and Philip would come up with the reinforcements, if only to put a stop to this wholesale massacre.

Thousands of Indians were pent up in the square of the sacrifice, all arrayed in festal robes of white with chaplets of flowers. These latter were now torn off and cast underfoot, the white garments were spotted with blood—the blood of their friends—and, frantic with rage, the multitude did all that valour could do to break through the handful of men holding the bridges. The drums were rolling their thunder incessantly, the trumpets shrieked like human beings, priests bellowed, the worshippers yelled, and constantly could be heard the ominous cracking of the rifles, as every shot carried death into the white mass heaving tumultuously in the square.

All at once a trumpet beyond the walls rang out clear and thin.

"Hurrah!" cried Jack, waving his sword, "the reinforcements at last."

It was indeed the seven hundred men, who had arrived sooner than was expected. Martez, anxious to aid his leader as speedily as possible, had marched his men rapidly along the narrow path, and now they were steadily streaming through the gate, making for the several bridges where the fight seemed hottest. As the priests were shouting down encouragements to the people below, Rafael decided to attack the teocalli, and stop this work. Once the shrine was taken, and it was possible the Indians might yield without further trouble, a thing he heartily desired, as, like Jack, he was weary of this massacre.

Tim and Martez stayed with Don Rafael, while Philip joined Jack, and Peter, who was quite war-like in appearance, went to the town bridge, where Riconada was fighting. At a given signal, all three bodies of soldiers commenced to converge towards a single point, that being the teocalli. The priests saw this manœuvre, and bellowed with fear. Many threw themselves down the steep sides of the pyramid, in vain offering themselves to the war-god in the hope that he would decree victory to their fellow-countrymen. The women in the square were shrieking wildly, and hurling stones, wrenched from the houses, at the soldiers as they pushed the mass of men steadily before them. From the summit of the pyramid a cloud of incense rolled heavenward, and Ixtlilxochitli, in the red robe of sacrifice, stepped forward to the verge of the steps, holding up the opal in order to encourage his people.
