Don, if you ever get a chance to visit Fort Benning, Georgia, go their Infantry Museum. They have one whole wing devoted to medical care and especially that during the Civil War. I don't care how strong your stomach is, it will make you sick--at least it did me. They have bunches of pictures taken at field hospitals. There are pictures outside of the tents showing wagon loads of amputated limbs. There are exhibits of surgical equipment, saws, scalples, etc. that I wouldn't want to use on a dead dear, let alone on a live soldier, without any antesetic and being held down by four or five orderlies while the Doctor cut off his limb(s). It is really gruesome.
