At three o'clock in the morning the sleepers were routed out with the order "stand to." Though the Khaki Boys could not know it, a patrol had returned half an hour before with the information that they had surprised a Boche wiring party, who were busily engaged in cutting lanes in their own wires, and had killed two of them. This looked decidedly suspicious, to say the least. The patrol was of the belief that an attack on the American trench would soon begin, followed by a raiding party of Boches.
Shortly after the Khaki Boys had taken up their positions on the fire-step, the German guns began a furious bombardment of the American trench, forcing the men to shelter themselves behind the parados. The parados, in this particular trench, were composed of squares of sandbags built up at intervals for a distance of about three feet behind the parapet, leaving a lane in the trench just wide enough for passage back and forth behind them. These parados did much to avert casualties caused from bits of bursting high-explosive shells.
The American batteries lost no time in opening up on the Germans, returning their fire with equal fury. For a while the din was terrific. Shells screamed overhead, causing a pandemonium of racket. Bursting, their fire made No Man's Land almost as light as day. In the trench many Sammies were dropping, wounded or killed by pieces of exploding shell. The Khaki Boys were receiving their baptism of fire in earnest.
It was a battle in which the Sammies themselves took small part, save to crouch in the trench, shielding themselves as best they could from that devastating rain of fire. The noise was too great for them to make themselves heard in passing an order, save by cupping hands to mouth and yelling as loudly as they could.
For an hour each side continued to bombard the other's trenches. All along the parapet of the American trench yawning gaps began to appear. As fast as one was made, men set to work upon it to repair the damage before dawn should appear and expose the Sammies to the rifle and machine-gun fire of the Boches.
The Khaki Boys turned to with a will. Some filled sandbags with mud, others rebuilt the shattered parados and stopped the gaps in the parapet. Toiling with desperate energy, they could only hope that the American guns were doing much heavier damage to the Fritzies' fire trench. They had faith that their own artillery could register more telling hits than that of the enemy.
Considering the number of shells that the Germans were sending over, many of them had been aimed in the direction of the flare from the American batteries. These passed right over the trenches. The American guns continuing to keep up a constant thundering, it looked as though the Boches had not succeeded in wiping out any of these batteries.
The gray light of dawn showed first glimpse of the enemy trenches. It was a sight that cheered the Sammies immensely. Gap after gap yawned in the parapet of their fire trench, through which could be seen plainly the forms of German soldiers, hurrying back and forth or toiling desperately to re-establish a protecting wall between themselves and the Sammies.
If the Boches had intended to raid it seemed evident that they had given it up as a bad job and devoted themselves strictly to the business of playing safe.
With daylight their guns suddenly became silent. The American batteries went on hammering at them, however, for some time after the Boche artillery had ceased firing.
