Cold Harbor, 1865
Undated, Source Unknown
These images will never cease to haunt me, it is so easy to forget the mortality of warfare beyond numbers and dates until it is thrown on your doorstep in it's visual form. I cannot imagine the kinds of corpses grave diggers encountered on a regular basis or the lasting psychological effect of such exposure to vast amounts of mangled unidentifiable bodies.
EDIT: Title and sourcing adjustments in light of more accurate information.
