Then the battalion crawled over the embankment and moved along the lines of twisted rails. Trent rolled up his trousers and tucked them into his woollen socks: but they halted again, and some of the men sat down on the dismantled railroad track. Trent looked for his wounded comrade from the Beaux Arts. He was standing in his place, very pale. The cannonade had become terrific. For a moment the mist lifted. He caught a glimpse of the first battalion motionless on the railroad track in front, of regiments on either flank, and then, as the fog settled again, the drums beat and the music of the bugles began away on the extreme left. A restless movement passed among the troops, the colonel threw up his arm, the drums rolled, and the battalion moved off through the fog. They were near the front now for the battalion was firing as it advanced. Ambulances galloped along the base of the embankment to the rear, and the hussars passed and repassed like phantoms. They were in the front at last, for all about them was movement and turmoil, while from the fog, close at hand, came cries and groans and crashing volleys. Shells fell everywhere, bursting along the embankment, splashing them with frozen slush. Trent was frightened. He began to dread the unknown, which lay there crackling and flaming in obscurity.
