When the lieutenant entered, Paul said, so as to be heard by all and especially by the major: "I recommend that scoundrel to your care, lieutenant. It's Major Hermann, one of the chief spies in the German army. I have the proofs on me. Remember that, in case anything happens to me. And, if we should have to retreat. . . ." The lieutenant smiled: "There's no question of that. We shall not retreat, for the very good reason that I would rather blow up the shanty first. And Major Hermann, therefore, would be blown up with us. So make your mind easy." The two officers discussed the defensive measures to be adopted; and the men quickly got to work. First of all, the bridge of boats was unmade, trenches dug along the canal and the machine-guns turned to face the other way. Paul, on his first floor, had the sandbags moved from the one side of the house to the other and the less solid-looking portions of the wall shored up with beams. At half-past five, under the rays of the German flashlights, several shells fell round about. One of them struck the house. The big guns began to sweep the towpath. A few minutes before daybreak, a detachment of cyclists arrived by this path, with Bernard d'Andeville at their head. He explained that two companies and a section of sappers in advance of a complete battalion had started, but their progress was hampered by the enemy's shells and they were obliged to skirt the marshes, under the cover of the dyke supporting the towpath. This had slowed their march; and it would be an hour before they could arrive. "An hour," said the lieutenant. "It will be stiff work. Still, we can do it. So . . ." While he was giving new orders and placing the cyclists at their posts, Paul came up; and he was just going to tell Bernard of Major Hermann's capture, when his brother-in-law announced his news: "I say, Paul, dad's with me!" Paul gave a start: "Your father is here? Your father came with you?" "Just so; and in the most natural manner. You must know that he had been looking for an opportunity for some time. By the way, he has been promoted to interpreter lieutenant. . . ." Paul was no longer listening. He merely said to himself: "M. d'Andeville is here. . . . M. d'Andeville, the Comtesse Hermine's husband. He must know, surely. Is she alive or dead? Or has he been the dupe of a scheming woman to the end and does he still bear a loving recollection of one who has vanished from his life? But no, that's incredible, because there is that photograph, taken four years later and sent to him: sent to him from Berlin! So he knows; and then . . . ?" Paul was greatly perplexed. The revelations made by Karl the spy had suddenly revealed M. d'Andeville in a startling light. And now circumstances were bringing M. d'Andeville into Paul's presence, at the very time when Major Hermann had been captured. Paul turned towards the attic. The major was lying motionless, with his face against the wall.
