A yell arose from friend and foe alike as they saw the glint of the stone, and the Indians closed resolutely round the base of the teocalli in a vain attempt to prevent the enemy from taking it by storm. All their valour and self-sacrifice was in vain. The three compact bodies of men pushed forward, shoulder to shoulder, through the white mass, leaving behind three several streaks of red and yellow, the uniformed bodies of their fellow-countrymen. Ixtlilxochitli saw these rivers of fierce soldiery converge towards the staircase of the teocalli, and yelling aloud to Huitzilopochtli, flashed the opal incessantly in the sun.

"There is Xuarez!" panted Philip, in the ear of Jack, as they cut their way onward.

"Where?"

"By Ixtlilxochitli. That chap in red. He is bound. By Jove, Jack, I believe the old fiend meant to sacrifice him."

"Pity he didn't," retorted Jack, grimly; "look out Philip. Ah, there is Tim. Hurrah, Tim! See which of us will reach the staircase first."

Even in the midst of danger, Jack could not help joking, and Tim burst out laughing as he hurled his huge form by Rafael through the crowd.

All at once their mirth ended. At the foot of the teocalli they stumbled over a nude corpse with a ragged wound in the breast. It was the body of Cocom.

"He has been sacrificed," cried Jack, fiercely. "Forward men! Avenge his death."

The advancing troops cheered loudly, and pressed steadily on towards the great pyramid.

The soldiers in the other part of the city had set fire to the dwellings, and already the flames were rising heavenward. Mad with rage, the Indians fought on doggedly, but could do nothing against the discipline of regular troops; inch by inch they gave way before the line of steel pressed against their breasts. The invaders stepped over corpses on their way to the teocalli, and those lying on the ground not yet dead, twining their arms round the legs of their foes, strove to throw them. The noise was something deafening, and the whole square was one vast field of carnage.
