I was at the front for thirteen months, and by the end of that time … [t]he war had become an everyday affair; life in the line a matter of routine; instead of heroes there were only victims … [T]here was no rhyme or reason in all this slaughtering and devastation; pain itself had lost its meaning; the earth was a barren waste … Most people have no imagination. If they could imagine the sufferings of others, they would not make them suffer so.
(Diary of Ernst Toller, German soldier, 1916)
