The Mexican noble turned and repeated the words in stern tones.

"We will set an example to any who may show fear," he said. "Consider that you are fighting for home and children. Let no one say that we were afraid of a noise."

The words seemed to hearten the men, and though the guns continued firing for some little while, no one moved, no one was hit, and only a few bricks were dashed from the wall. It was plain that there was nothing to be done in this manner, and the Spanish commander gave an order.

"We will advance against them," he said, in scornful tones. "They will run when they see our swords. Let the men with sword and buckler march on the right, and those with lances on the left. The men with the crossbows can be on either flank."

They formed at once, and came forward at a smart pace, looking so numerous, with thousands of the native allies swarming about them, that the Mexicans again showed signs of losing heart. But Roger soon reassured them. He leaped on to the wall, where all could see him, and called to Teotlili—

"Let the crossbow-men prepare their weapons and creep up to the back of the wall," he said; "and shout to those stationed in the canoes to come close to the shore. When I call out, they are to fire into the enemy. The men with the lances are to form up at either end of the wall, and are to be ready to rush out on the Spaniards and their allies. Let all follow my shout with another."

The order was promptly repeated, and Roger, looking down from his high perch, saw that all was in readiness. The faces of the Mexicans now showed eagerness and determination; for the sight of their leader standing there with the Spanish shafts flying past him, gave them courage. A little while ago they had found it hard to stand up to the Spaniards, but now they had learned something. They had seen this youth defy them and hoodwink their horsemen, and they argued that if he could do that, then they also might hope for success. Therefore the men silently crept to the back of the wall, while the lancers, each with one of the English to command them, stole softly to either end, and waited the moment for battle. It came sooner than they expected.

"Take them with a rush!" shouted the Spanish leader. "Now, charge down on them!"

He and his men gave vent to a chorus of shouts, which was followed by those of the natives, and by their curious shrill whistles. Then the whole mass dashed forward impetuously, aiming for the wall which had been erected across the approach to the aqueduct.

"Ready!" shouted Roger, and at the signal, some thousand voices took up the shout, while the top of the wall was lined with the heads and shoulders of the crossbow-men. Then numbers of canoes dashed from under the aqueduct, and ferrying in close to the shore, came to a stop. At once a cloud of shafts sang in the direction of the enemy, and some score of their numbers fell to the ground. But it did not even cause the Spaniards to hesitate, though many of the allies came to a sudden halt. They repeated their shout, and dashed forward at an even greater pace, their swords above their heads, and their bucklers ready before them to keep off the shafts. The lancemen on the left, however, had little protection, and a nod from Roger caused Teotlili to direct the aim of the majority against them.
