Paths of Glory by Irvin S. Cobb

It was late in the short afternoon, and getting close on to twilight, when we got back into the town. Except for the soldiers there was little life stirring in the twisting streets. There was a funeral or so in progress. It seemed to us that always, no matter where we stopped, in whatsoever town or at whatsoever hour, some dead soldier was being put away. Still, I suppose we shouldn't have felt any surprise at that. By now half of Europe was one great funeral. Part of it was on crutches and part of it was in the graveyard and the rest of it was in the field.

Daily in these towns back behind the firing lines a certain percentage of the invalided and the injured, who had been brought thus far before their condition became actually serious, would die; and twice daily, or oftener, the dead would be buried with military honors.
