But a succinct account of the whole business would be to say that for four years the flower of the country's population were engaged in killing each other. All other industries were overshadowed by the occupation of human slaughter. Shop and farm, church and college, school and home, all were subsidiary to the battlefield.
The battlefield itself is not easily conceived by the civilian, even with the aid of poets and story-tellers from Homer to Kipling. The reader, who has perhaps never seen a shot fired in anger, may have chanced to witness a man struck down in the street by a falling beam or trampled by a runaway horse. Or, as a better illustration, he may remember in his own case some hour of sudden and extreme suffering,--a hand caught by a falling window, a foot drenched by scalding water. Intensify that experience, extend it through days, for the home couch and the nursing of mother or wife put the bare ground and the onrush of hostile men,--and you have the nucleus, the constituent atom, of a battle. Multiply it by hundreds or thousands; give to each sufferer the background of waiting parents, wife, children, at home; give to a part death, swift or agonizing; to another part lifelong infirmity or irritation,--and you begin to get the reality of war.
It was Wellington who said that the worst sight on earth, next to the field of defeat, was the field of victory. It was Lee who wrote from Mexico to his son: "You have no idea what a horrible sight a battle-field is." And he said that the strongest memory left from his first battle was the plaintive tone of a little Mexican girl whom he found leaning over a wounded drummer-boy.
Men not only witness such carnage but inflict it, in the excitement of battle, because animated by feelings of which only a part can rightly be called heroic. Honor indeed is due to the subordination of personal fear to the sense of duty and comradeship,--yes, high honor; and the appeal of the soldier to the imagination, as a type of self-sacrifice and nobility, has its element of truth. But the ordinary courage of the battle-field is largely an excitement half-animal, half-contagious, running often into savagery and insensate fury. In that situation the highest and lowest elements in man come into play. For the most part only the highest is portrayed for us by the historians and romancers,--they keep the wild beast and the devil out of sight. Only in these later days, when mankind begins to scrutinize its boasted glories more closely, do Tolstoi in literature and Verestchagin in art give us glimpses of the grim reality.
