No Man's Land by H.C. McNeile

And so it came about that three months later Reginald Simpkins -- lance-corporal -- and Shorty Bill -- private -- were seated on the fire-step of a trench side by side. With one continuous droning roar the shells passed over their heads and crumped into the German lines opposite. The days of peace for the battalion were over; in a quarter of an hour they were going over the top. Thousands like them sat on similar fire-steps and realised that same fact, for it was no little show this time: it was one where divisions and corps were involved. But to the pawns in the game, the horizon is limited: it is just their own destination, their own life, their own fate that looms up big and blots out the rest. It's not the other hundred thousand who matter at the moment -- it's the pawn himself who wonders, and laughs, and sings, and prays. .

Shorty, smoking his pipe imperturbably, was feeling the edge of his own particular weapon, with critical finger, and every now and then stealing a look at the boy beside him. Apparently satisfied at last with its sharpness he laid it down on the step and turned to our friend.
