Tom nodded and the lieutenant passed to Ollie and George Harper, and so on from man to man along the entire section of trench occupied by Company C.

In forty-five minutes! The time was getting close. Well, anything was better than remaining there motionless under such a strain, not knowing at what moment a Boche shell might come thundering into their shallow stopping place to spread sudden death and mortal injury.

Men began tightening and adjusting their equipment, examining their rifles, cartridge belts and small arms.

A Salvation Army man came down the trench lugging a great can of steaming coffee. The boys of Company C greeted him with cheers which their lips formed but their voices could not make heard; and as they took cautious quaffs of the hot beverage it seemed to soothe ragged nerves and give them new vigor.

Tom looked at his wrist watch and compared it with Harper’s. They were exactly the same time. But half an hour now remained.

That instant marked another move in the game, too. In little groups men climbed out of the trench and went forward. Tom knew instinctively that they were the dare-devil wire-cutters—that the American artillery, adjusted like clockwork, had moved forward and these men were going out to cut away any entanglements that it had not smashed and entirely destroyed.

In this conflict war had become an exact science, and the men going out knew that except for an occasional German shell that might fall in their vicinity they were working behind an invincible screen of steel and fire.

There flashed across Tom Walton’s mind the picture of General Pershing as he had seen him on the preceding day in conference with the officers who were to direct and carry out the gigantic project which he and the other great commanders had formulated; and in the recollection Tom found new confidence and determination. Whatever indecision may have possessed him fell away; it was as though he suddenly had been shorn of shackles which weighted him down; he breathed in deeply of the powder-tainted air, and his only sensation was that of a great and noble strength of purpose.

Tom examined his watch again. But ten minutes more!

Suddenly, almost with as great a shock as it had begun, the firing ceased. If the expression can be made, the tremendous silence that fell upon the area came like a crash. For the men had become gradually tuned up to the dreadful uproar, and to have it abruptly break off set their heads ringing.
