Erich Maria Remarque

But now, for the first time, I see you are a man like me. I thought of your hand-grenades, of your bayonet, of your rifle; now I see your wife and your face and our fellowship. Forgive me, comrade. We always see it too late. Why do they never tell us that you are poor devils like us, that your mothers are just as anxious as ours, and that we have the same fear of death, and the same dying and the same agony — Forgive me, comrade; how could you be my enemy?

We march up, moody or good-tempered soldiers — we reach the zone where the front begins and become on the instant human animals.
