General Jackson did not move, save to lift his glasses now and then, as if with their magnifying powers he could pierce the dark. But the night and the swollen fog still hid everything going on beyond the river from those on the heights. Down by the shore the Mississippians in their rifle pits might see a little, and the scouts undoubtedly had seen much, else the signal guns would not be firing. Harry's pulses, after a while, began to beat more smoothly and there was not such a painful and insistent drumming in his head. Emotions yielded now to will and he waited patiently. General Jackson for the first time told some of his young officers that they could lie down and rest. "There can be no action before daylight," he said, "and it's best to be fresh and ready." He spoke to them with the grave kindness that he always used, save when some great fault was committed, and then his words burned like fire. Harry and Dalton procured their blankets from their tents, wrapped them about their bodies and lay down on the dryest spots they could find, but they had no thought of sleep. They permitted their limbs to relax, and that was a help to the nerves, but neither closed his eyes. Those dark hours seemed an eternity to Harry. The floating fog seemed to grow thicker and to enter his very bones. He shivered and drew the blanket close. Now, with his ears close to the earth, he was sure that he could hear the axes and the saws and the hammers beating on steel rivets on the other side of the Rappahannock. The Confederate cannon still fired the signals of alarm at regular intervals, but the night and the fog always closed in again quickly over the flash that the discharge had made. After a while a murmur came from the long Southern line along the heights and on the ridges. Horses stirred here and there, cannon, moved to new positions, made sighing sounds as their wheels sank in the mud; sabres and bayonets clanked, thousands of men whispered to one another. All these varying sounds united into one great soft voice which was like the murmur of a wind through the summer night. Toward five o'clock in the morning, when the darkness had not diminished a whit, a messenger from General Lee rode up with a note for General Jackson. It merely stated that all was ready and to hold the positions that he had taken up the night before. Jackson wrote a brief reply by the light of a lantern that an orderly held, and the messenger galloped away with it. It was the only incident that had occurred in a long time. "They're not using many lights on the other side of the river," said Harry, although he noted an occasional flame in the darkness. "Of course, they want to hide their bridge building, but you'd think they'd have fires burning elsewhere." "They've learned the value of caution," said Dalton. "I'm bound to say they're going about the first part of their work with skill." He spoke with the calm superiority of a young Officer.
