Pvt Smith seems to have survived wounded for some time after the first Cold Harbor. This suggests that he might have been taken to Richmond, which was well on its way to being the largest hospital city on earth by this time.

The area was not scoured for human remains after the first battle.Giving the remains a close inspection through either enlargement or a good magnifier might reveal some clues to identity. How were those fellows dressed?
