"I see them all," said Harry, "and I think you're right. I'll ride back peaceably to General Lee in the morning, and tell him that I left ten thousand cavalrymen lying lazily on the grass, and ten thousand horses eating their heads off near Brandy Station." "But to-night you rest," said one of the young officers. "Do you smoke?" "I've never learned." "Well, I don't smoke either unless we get 'em from the Yankees. Here's what's left of a box that we picked up near the Chancellor House. It may have belonged to Old Joe Hooker himself, but if so he'll never get it back again." He distributed the cigars among the smokers, who puffed them with content. Meanwhile the noises of the camp sank, and presently Harry, taking his blankets and saying good night, went to sleep in the Inn of the Greenwood Tree. CHAPTER XI THE CAVALRY COMBAT Harry was a fine sleeper. One learns to be in long campaigns. Most of those about him slept as well, and the ten thousand horses, which had been ridden hard in the great display during the day, also sank into quiet. The restless hoofs ceased to move. Now and then there was a snort or a neigh, but the noise was slight on Fleetwood Hill or in the surrounding forests. A man came through the thickets soon after midnight and moved with the greatest caution toward the hill on which the artillery was ranged. He was in neither blue nor gray, just the plain garb of a civilian, but he was of strong figure and his smoothly shaven face, with its great width between the eyes and massive chin, expressed character and uncommon resolution. The intruder--he was obviously such, because he sought with the minutest care to escape observation--never left the shelter of the bushes. He had all the skill of the old forest runners, because his footsteps made no sound as he passed and he knew how to keep his figure always in the shadows until it became a common blur with them. His was a most delicate task, in which discovery was certain death, but he never faltered. His heart beat steadily and strong. It was an old risk to him, and he had the advantage of great natural aptitude, fortified by long training in a school of practice where a single misstep meant death. The sharp eyes of the spy missed nothing. He counted the thirty pieces of artillery on the hill. He estimated with amazing accuracy the number of Stuart's horsemen. He saw a thousand proofs that the heavy firing he had heard in the course of the day was not due to battle with Northern troops. Although he stopped at times for longer looks, he made a wide circuit about the Confederate camp, and he was satisfied that Stuart, vigilant and daring though he might be, was not expecting an enemy.
