It would indeed have made a vast amount of difference, and would nearly certainly have led to capture or death. But these Mexicans had a blind faith in their war god and other deities, and groaned under a system of superstition which the priests took good care to keep alive. It would have been far easier, and far better for themselves, to fling themselves against these foreigners with their best arms, and cut them down by sheer advantage of numbers. But their superstition taught them that a sacrifice was needed, that prisoners should not be slain in battle, but merely taken with as little hurt as possible, so that they might be afterwards offered to their idols. And now that they had a huge and strange opponent to deal with, one who fought with his hands in a manner which none had ever seen, they still adhered to their practice, determining to take him alive. It gave Roger and his comrade an enormous advantage--an advantage which they needed, however, even though they held such a commanding position. For the Mexicans had the numbers. Life was of no consequence, and they were prepared to throw away many of their fighting men to attain their object. The insult to their deities lent added desperation to their attack, and when they advanced up the stairs again it was with the determination to conquer. They found on the upper side of the barrier a young giant filled with equal determination, prepared to seize his enemies, and, if he were surrounded and capture imminent, to drag them all by sheer force to the edge of the tower, and there hurl himself and his captors to the court below. Yes; let the reader imagine himself in a similar predicament, and he may realize to some small degree the desperate valour with which Roger was filled, and the reckless thoughts which flowed through his mind. "Anything is better than that hideous altar and the sacrifice," he told himself; and he prepared to act up to the thought. But the Mexicans were advancing, and a shout rang out from the stairs below. It was answered from every quarter of the city, telling the defenders that thousands were waiting to learn the issue, and to praise their comrades if successful. There was movement on the towers all round, seen by the aid of the fires, while a murmur came from the courts below. "Waiting for us," said Roger, grimly. "We will give them work to do before we are taken. Now, prepare."
