"He asks whether you will all give a pledge to remain silent, as we march out. If you will do so, he will accept your promise; but if not, he will be forced to gag you, as the safety of the army depends upon our getting beyond the streets, before our march is discovered."
"I wonder that they are ready to take our promise," Cacama said disdainfully, "after their own treachery. However, an Aztec noble is not like a Spaniard. Our faith may be depended upon. We will give our word to be silent."
The other prisoners also promised, and were allowed to take their places in the column, ungagged.
The alarm was given long before the rear of the column had got out from the street. Cacama gave an exclamation of joy, when he heard the silence broken by loud cries at the end of the street; and immediately afterwards by the shouts of the priests on the lofty temples, by the blowing of horns, and the beating of the great war drum.
"The game has begun," he said. "We shall see how many Spaniards remain alive, when the sun rises. Long before they can get across the causeway, our people will be upon them. We shall not see the triumph, for without defensive armor we shall fall, in the darkness, beneath the missiles of our own people. That matters not. Better to die at the hands of a Mexican, struggling to be free, than at those of these treacherous invaders."
The missiles showered down thickly upon the column, from the houses, till they emerged from the street and made their way out on to the causeway. Then they became exposed to the storm of arrows, darts, and stones from the canoes on the lake. By their officer's orders, the soldiers immediately in charge of the prisoners drew their swords and formed a circle round them; with orders to fall upon and kill them, at once, did they make the slightest movement to escape. Roger translated to the captives the officer's assurance that, although he was most anxious for their safety, he had no resource but to order the soldiers to slay them, at once, if they made any movement to escape.
"We shall not try to escape," Cacama said. "How can we do so, with our hands bound?"
During the long pause that ensued, before the rear of the column passed over the bridge on to the causeway, the impatience among the soldiers was great. Many had already fallen beneath the missiles of the enemy. Scarce one but had received wounds, more or less severe. Several of the prisoners, too, had fallen.
"What is it?" Cacama asked, as the cry of despair went up; when it became known that the bridge was immovable, and that there were no means of crossing the breaks in the causeway, ahead.
He muttered an exclamation of triumph, when Roger repeated to him the news he had just learned.
