All Quiet On The Western Front: by Erich Maria Remarque.

Most accounts of war are bugle led parades, with heros marching to supposed victory, This is the first time a book, a film dared to be different, telling the story of little boys marching to war with all its ignominies and death being merely one of the many horrible facts they endured that no one ought to have to go through. Revolutionary for its time and all the more so because it was about the first world war, assumed to be the lesser horror of the two whether wrongly or not.
