"They scared us badly enough as it was, sir," said St. Clair.

Colonel Leonidas Talbot smiled slightly.

"That part of it at least will do you good," he said. "You young men don't know what war is, and you are growing fat and saucy in a pleasant country in June. But there is something ahead that will take a little of the starch out of you and teach you sense. No, you needn't look inquiringly at me, because I'm not going to tell you what it is, but go get some sleep, which you will need badly, and be ready at four o'clock this afternoon, because the Invincibles march then and you march with them."

Harry and St. Clair saluted and retired. They knew that it was not worth while to ask Colonel Talbot any questions. Since he had met him again in Virginia, Harry had recognized a difference in this South Carolina colonel. The kindliness was still there, but there was a new sternness also. The friend was being merged into the commander.

They chose a tent in order to shut out the noise and make sleep possible, but on their way to it they were waylaid by Langdon, who had heard something of their adventure the night before, and who felt chagrin because he had lacked a part in it.

"Although everything generally happens for the best, there is a slip sometimes," he said, "and I want to be in on the next move, whatever it is. There is a rumor that the Invincibles are to march. You have been before the colonel, and you ought to know. Is it true?"

"It is," replied Harry, "but that's all we do know. He was pretty sharp with us, Tom, and among our three selves, we are not going to get any favors from Colonel Leonidas Talbot and Lieutenant-Colonel Hector St. Hilaire because we're friends of theirs and would be likely to meet in the same drawing-rooms, if there were no war."

Harry and St. Clair slept well, despite the noises of a camp, but they were ready at the appointed time, very precise in their new uniforms. Langdon was with them and the three were eager for the movement, the nature of which officers alone seemed to know.

The Invincibles were an infantry regiment and the three youths, like the men, were on foot. They filed off to the left behind the front line of the Southern army, and marched steadily westward, inclining slightly to the north. Many of the men, or rather boys, not yet fast in the bonds of discipline, began to talk, and guess together about their errand. But Colonel Talbot and Lieutenant-Colonel St. Hilaire rode along the line and sternly commanded silence, once or twice making the menace of the sword. The lads scarcely understood it, but they were awed into silence. Then there was no noise but the rattle of their weapons and the steady tread of eight hundred men.

The young troops had been kept in splendid condition, drilling steadily, and they marched well. They passed to the extreme western end of the Confederate camp, and continued into the hills. The sun had passed its zenith when they started and a pleasant, cool breeze blew from the slopes of the western mountains. The sun set late, but the twilight began to fall at last, and they saw about them many places suitable for a camp and supper. But Colonel Talbot, who was now at the head of the line, rode on and gave no sign.
