"—I see all the little signs, getting ready in the hospitals &c.—it is dreadful, when one thinks about it—I sometimes think over the sights I have myself seen, the arrival of the wounded after a battle, & the scenes on the field too, & I can hardly believe my own recollection—what an awful thing war is—Mother, it seems not men but a lot of devils & butchers butchering each other—"
Walt Whitman in a letter to his mother dated March 22, 1864
