To-morrow he would meet for the first time, on the rolling fields of Waterloo, the only captain of a European army whom he had not defeated. He wanted to think his plans of battle over in silence. Some time he paced up and down the room, his chin drooping forward on his breast, and his hands clasped upon his back. Through the wide, clear spaces of his mind great armies passed in black procession, moving like storm-clouds over the stricken earth; burning cities rose in the distance, amid the shrieks of dying men, and the thunder of cannon. His plan was at last matured. Victory? Yes, that was certain! So his thoughts ran. An aide-de-camp entered with a dispatch. He tore it open, and ran his eye over it. "It is nothing," he said. "Don't disturb me for two hours except on a matter of great importance. I want to sleep." Going up to the old armchair of oak that was set before the fire, he fell on his knees, and covered his eyes and prayed. "What!" said the man who was watching him up in the rafters. "Does Cain dare to pray? Surely God will not answer his prayers! He is praying that he may wipe the English to-morrow from the face of the earth, and again cement his throne with blood, and forge his sceptre of fire!" That, no doubt, was what Napoleon prayed for. Yet, when he rose up his face was wonderfully changed and softened by the religious light which had shone on it for a few moments. Then, throwing himself into the armchair, he closed his eyes. And, as the fire burnt low, Rohan Gwenfern silently descended from the loft, and something gleamed in his hand. He crept up to the sleeping emperor, and stared at his face, reading it line by line. Napoleon moved uneasily in his sleep, and murmured to himself, and his hand opened and shut. As Rohan raised his knife to strike home to the heart of the tyrant he saw the hand--white and small, like a woman's or a child's. Again he looked at the face. Ah, there was no imperial grandeur here! Only a feeble, sallow, tired, and sickly creature, whom a strong man could crush down with one blow of his fist. Rohan grew weak as he looked, and the long knife almost fell from his clutch. "I must kill him--I must kill him!" he kept saying to himself. "His one life against the peace and happiness of earth--the life of a Cain! If he awakens, war will awaken, and fire, famine, and slaughter! Kill him, Rohan, kill him!" Perhaps if Napoleon had not prayed before he slept, his enemy would have carried out his purpose. But he had prayed; his face had become beautiful for a moment, and he fell asleep as fearlessly as a child. No! Rohan Gwenfern was not made of the stuff of which savage assassins are formed; though there was madness in his brain, there was still love in his heart. He could not kill even Cain, when God had sanctified the murderer with sleep. God had made Napoleon, and God had sent him; bloody as he was, he, too, was God's child.
