Along the rear of the brigade of infantry a column of cavalry was sweeping at a hard gallop. A lieutenant, riding some yards to the right of the column, bawled furiously at the four troopers just at the rear of the colours. They had lost distance and made a little gap, but at the shouts of the lieutenant they urged their horses forward. The bugler, careering along behind the captain of the troop, fought and tugged like a wrestler to keep his frantic animal from bolting far ahead of the column. On the springy turf the innumerable hoofs thundered in a swift storm of sound. In the brown faces of the troopers their eyes were set like bits of flashing steel. The long line of the infantry regiments standing at ease underwent a sudden movement at the rush of the passing squadron. The foot soldiers turned their heads to gaze at the torrent of horses and men. The yellow folds of the flag fluttered back in silken, shuddering waves, as if it were a reluctant thing. Occasionally a giant spring of a charger would rear the firm and sturdy figure of a soldier suddenly head and shoulders above his comrades. Over the noise of the scudding hoofs could be heard the creaking of leather trappings, the jingle and clank of steel, and the tense, low-toned commands or appeals of the men to their horses; and the horses were mad with the headlong sweep of this movement. Powerful under jaws bent back and straightened, so that the bits were clamped as rigidly as vices upon the teeth, and glistening necks arched in desperate resistance to the hands at the bridles. Swinging their heads in rage at the granite laws of their lives, which compelled even their angers and their ardours to chosen directions and chosen faces, their flight was as a flight of harnessed demons. The captain's bay kept its pace at the head of the squadron with the lithe bounds of a thoroughbred, and this horse was proud as a chief at the roaring trample of his fellows behind him. The captain's glance was calmly upon the grove of maples whence the sharpshooters of the enemy had been picking at the blue line. He seemed to be reflecting. He stolidly rose and fell with the plunges of his horse in all the indifference of a deacon's figure seated plumply in church. And it occurred to many of the watching infantry to wonder why this officer could remain imperturbable and reflective when his squadron was thundering and swarming behind him like the rushing of a flood. The column swung in a sabre-curve toward a break in a fence, and dashed into a roadway. Once a little plank bridge was encountered, and the sound of the hoofs upon it was like the long roll of many drums. An old captain in the infantry turned to his first lieutenant and made a remark, which was a compound of bitter disparagement of cavalry in general and soldierly admiration of this particular troop.
