It was a favorite air of the Southern bands, and, much as it stirred Harry now, he was destined to hear it again in moments far more thrilling. He presented his order from General Beauregard to a sentinel, who passed him to an officer, who in turn told him to go about a quarter of a mile westward, where he would find the regiment of Colonel Talbot quartered. "It's a mixed regiment," he said, "made up of Virginians, South Carolinians, North Carolinians, and a few Kentuckians and Tennesseeans, but it's already one of the best in the service. Colonel Talbot and his second in command, Lieutenant-Colonel St. Hilaire, have been thrashing it into shape in great fashion. They're mostly boys and already they call themselves 'The Invincibles.' You can see the tents of their commanding officers over there by that little creek." Harry's eyes followed the pointing finger, and again his heart leaped. His friends were there, the two colonels for whom he had such a strong affection, and the two lads of his own age. Theirs looked like a good camp, too. It was arranged neatly, and by its side flowed the clear, cool waters of Young's Branch, a tributary of the little Manassas River. He walked briskly, crossed the brook, stepping from stone to stone, and entered the grounds of the Invincibles. A tall youth rushed forward, seized his hand and shook it violently, meanwhile uttering cries of welcome in an unbroken stream. "By all the powers, it's our own Harry!" he exclaimed, "the new Harry of the West, whom we were afraid we should never see again. Everything is for the best, but we hardly hoped for this! How did you get here, Harry? And you didn't bring Kentucky rushing to our side, after all! Well, I knew it wasn't your fault, old horse! Ho, St. Clair, come and see who's here!" St. Clair, who had been lying in the grass behind a tent, appeared and greeted Harry joyfully. But while Langdon was just the same he had changed in appearance. He was thinner and graver, and his intellectual face bore the stamp of rapid maturity. "It's like greeting one of our very own, Harry," he said. "You were with us in Charleston at the great beginning. We were afraid you would have to stay in the west." "The big things will begin here," said Harry. "There can be no doubt of it. Do you know, Harry, that we are less than thirty miles from Washington! If there were any hill high enough around here we could see the white dome of the Capitol which we hope to take before the summer is over. But we'll take you to the Colonel and Major Hector St. Hilaire, that was, but Lieutenant-Colonel Hector St. Hilaire that is."
