"I think I can," replied Dalton, also using glasses. "Four lights are there, and they are winking, doubtless to lights on another hill too far away for us to see." "It shows that the enemy at least is watching, and that while we may retreat unattacked it will not be unobserved. Hark! do you hear that, George? It's rifle shots, isn't it?" "Yes, and a lot of 'em, but they're a long distance away. I don't think we could hear 'em at all if it were not night time." "But it means something! There they go again! I believe it's a heavy skirmish and it's in the direction in which Sherburne rode." "The general's up. It's likely that one of us will be sent to see what it's all about." General Lee and his whole staff had risen and were listening attentively. The faint sound of many shots still came, and then a sharper, more penetrating crash, as if light field guns were at work. The commander beckoned to Harry. "Ride toward it," he said briefly, "and return with a report as soon as you can." Harry touched his cap, sprang upon his horse and galloped away. He knew that other messengers would be dispatched also, but, as he had been sent first, he wished to arrive first. He found a path among the trees along which he could make good speed, and, keeping his mind fixed on the firing, he sped forward. Thousands of soldiers lay asleep in the woods and fields on either side of him, but the thud of the horse's hoofs awakened few of them. Nor did the firing disturb them. They had fought a great battle three days long, and then after a tense day of waiting under arms, they had marched hard. What to them was the noise made by an affair of outposts, when they had heard so long the firing of a hundred and fifty thousand rifles and three or four hundred big guns? Not one in a hundred stood up to see. The country grew rougher, and Harry was compelled to draw his horse down to a walk. But the firing, a half-mile or more ahead, maintained its volume, and as he approached through thick underbrush, being able to find no other way, he dismounted and led his horse. Presently he saw beads of flame appearing among the bushes, seen a moment, then gone like a firefly, and as he went further he heard voices. He had no doubt that it was the Southern pickets in the undergrowth, and, calling softly, he received confirmatory replies. A rifleman, a tall, slender fellow in ragged butternut, appeared beside him, and, recognizing Harry's near-gray uniform as that of an officer, said: "They're dismounted cavalry on the other side of a creek that runs along over there among the bushes. I don't think they mean any real attack. They expect to sting us a little an' find out what we're about." "Seems likely to me too. They aren't strong enough, of course, for an attempt at rushing us. What troops are in here in the woods on our side?"
