"Certainly, we must try! We must get through them without further delay, for every moment now is of increasing importance."

Stealing forward from the bush, they slowly approached the line which the Germans were then preparing with entrenchments, and could now hear from those portions closest at hand the thud of busy picks and the ring of spades as the men employed them. Here and there a figure was to be seen standing up in the open, while everywhere else that column of men which had filed past them had, as it were, disappeared, or almost so; for already, thanks to the soft nature of the ground and to the rain which had fallen, the men had dug almost two feet down, and were partially hidden.

"Halt! Who are you? Why are you not working in the trenches?"

The question was bellowed at them by one of those figures standing out above the trenches, and, obedient to the order, losing their heads, indeed, for just one brief moment, Henri and Jules halted.

"Run for it!" whispered Henri; "straight through the line and on into the darkness! Come, Jules!"

Without a pause, without venturing to answer the question shouted at them, the two at once took to their heels, and, darting in between the men labouring at the trenches, sped on into the darkness. Nor was there any great attempt to arrest them; for, indeed, the men had already thrown off their tunics and had piled their arms, so that the only individuals carrying weapons were the officers superintending the operations. Half a dozen revolver-shots, therefore, were all that were fired at them, and those went wide in the darkness. Within a few minutes, in fact, the two were secure from all pursuit, and, provided there were no advance-parties thrown out in front of the Germans, might hope to reach their friends without further incident.

"But it is more than likely that pickets will have been posted, so as to avoid a French surprise," said Henri, "and, although I cannot claim much acquaintance with German methods as yet, one can imagine that sentries also have been sent towards our positions. Let's go on in silence, listening every now and again."

Stealing on through the darkness, they passed on more than one occasion a ghostly figure standing erect and motionless, keeping guard against the surprise of his comrades digging those trenches lower down the slope. Once, also, a figure suddenly sprang up before them—the figure of a German scout—a diminutive individual, who, not unnaturally, took them for comrades instantly.

"What now?" he said, standing within five feet of them. "Reliefs, or an advance-party in front of the main force? Surely not that, for it's time for us all to have a little rest, after the fighting we have experienced."

"Reliefs!" Henri told him instantly. "You are to return and report at the trenches. Go now, for we have fed, and no doubt you are hungry."
