" The doctors are busy with the repulsive but beneficent work of amputation. You see the sharp, curved knife enter the healthy, white body, you see the wounded man suddenly regain consciousness with a piercing cry and curses, you see the army surgeon fling the amputated arm into a corner, you see another wounded man, lying in a litter in the same apartment, shrink convulsively and groan as he gazes at the operation upon his comrade, not so much from physical pain as from the moral torture of anticipation. — You behold the frightful, soul-stirring scenes; you behold war, not from its conventional, beautiful, and brilliant side, with music and drum-beat, with fluttering flags and galloping generals, but you behold war in its real phase — in blood, in suffering, in death. "

― Leo Tolstoy , The Sebastopol Sketches
