The waters of the grim river curled away in a smile from the ends of the great boats, and slid swiftly beneath the planking. The dark, riddled walls of the town upreared before the troops, and from a region hidden by these hammered and tumbled houses came incessantly the yells and firings of a prolonged and close skirmish. When Dan had called his brother a fool, his voice had been so decisive, so brightly assured, that many men had laughed, considering it to be great humour under the circumstances. The incident happened to rankle deep in Billie. It was not any strange thing that his brother had called him a fool. In fact, he often called him a fool with exactly the same amount of cheerful and prompt conviction, and before large audiences, too. Billie wondered in his own mind why he took such profound offence in this case; but, at any rate, as he slid down the bank and on to the bridge with his regiment, he was searching his knowledge for something that would pierce Dan's blithesome spirit. But he could contrive nothing at this time, and his impotency made the glance which he was once able to give his brother still more malignant. The guns far and near were roaring a fearful and grand introduction for this column which was marching upon the stage of death. Billie felt it, but only in a numb way. His heart was cased in that curious dissonant metal which covers a man's emotions at such times. The terrible voices from the hills told him that in this wide conflict his life was an insignificant fact, and that his death would be an insignificant fact. They portended the whirlwind to which he would be as necessary as a butterfly's waved wing. The solemnity, the sadness of it came near enough to make him wonder why he was neither solemn nor sad. When his mind vaguely adjusted events according to their importance to him, it appeared that the uppermost thing was the fact that upon the eve of battle, and before many comrades, his brother had called him a fool. Dan was in a particularly happy mood. "Hurray! Look at 'em shoot," he said, when the long witches' croon of the shells came into the air. It enraged Billie when he felt the little thorn in him, and saw at the same time that his brother had completely forgotten it. The column went from the bridge into more mud. At this southern end there was a chaos of hoarse directions and commands. Darkness was coming upon the earth, and regiments were being hurried up the slippery bank. As Billie floundered in the black mud, amid the swearing, sliding crowd, he suddenly resolved that, in the absence of other means of hurting Dan, he would avoid looking at him, refrain from speaking to him, pay absolutely no heed to his existence; and this done skilfully would, he imagined, soon reduce his brother to a poignant sensitiveness.
