In the iron-gray dawn, while the troops were falling dimly and spectrally into line, and he was mounting his horse to be ready for orders, he remembered Gildersleeve's drunken tale concerning the commandant, and laughed aloud. But turning his face toward brigade headquarters (a sylvan region marked out by the branches of a great oak), he was surprised to see a strange officer, a fair young man in Captain's uniform, riding slowly toward it. "Is that the Boy's brother?" he said to himself; and in the next instant he had forgotten the whole subject; it was time to form and present the regiment. Quietly and without tap of drum the small, battle-worn battalions filed out of their bivouacs into the highway, ordered arms and waited for the word to march. With a dull rumble the field-pieces trundled slowly after, and halted in rear of the infantry. The cavalry trotted off circuitously through the fields, emerged upon the road in advance and likewise halted, all but a single company, which pushed on for half a mile, spreading out as it went into a thin line of skirmishers. Meanwhile a strange interview took place near the great oak which had sheltered brigade headquarters. As the unknown officer, whom Wallis had noted, approached it, Col. Waldron was standing by his horse ready to mount. The commandant was a man of medium size, fairly handsome in person and features, and apparently about twenty-eight years of age. Perhaps it was the singular breadth of his forehead which made the lower part of his face look so unusually slight and feminine. His eyes were dark hazel, as clear, brilliant, and tender as a girl's, and brimming full of a pensiveness which seemed both loving and melancholy. Few persons, at all events few women, who looked upon him ever looked beyond his eyes. They were very fascinating, and in a man's countenance very strange. They were the kind of eyes which reveal passionate romances, and which make them. By his side stood a boy, a singularly interesting and beautiful boy, fair-haired and blue-eyed, and delicate in color. When this boy saw the stranger approach he turned as pale as marble, slid away from the brigade commander's side, and disappeared behind a group of staff officers and orderlies. The new-comer also became deathly white as he glanced after the retreating youth. Then he dismounted, touched his cap slightly and, as if mechanically, advanced a few steps, and said hoarsely, "I believe this is Colonel Waldron. I am Captain Fitz Hugh, of the --th Delaware." Waldron put his hand to his revolver, withdrew it instantaneously, and stood motionless. "I am on leave of absence from my regiment, Colonel," continued Fitz Hugh, speaking now with an elaborate ceremoniousness of utterance significant of a struggle to suppress violent emotion. "I suppose you can understand why I made use of it in seeking you."
