.
In the poem "A March in the Ranks Hard-Prest, and the Road Unknown," by Walt Witman, the narrator describes the images of the wounded and dying soldiers he encounters at an old church, which is now serving as a hospital after battle. He uses phrases such as "a dim-lighted building" to refer to the church and sees "Shadows of deepest, deepest black, just lit by moving candles and lamps" inside it. He also mentions the continuous sight of blood, crying, devastated bodies, shadows and darkness he comes across, which create a mood of fright and mistery.
