Doubting that he was in one hospital for this one-year period, what was the procedure for soldiers too sick to travel? Leave them where they were and then add a note on the roll if/when they heard news of them?
That, to me, sounds like the case but I wondered if y'all had any other ideas. Ideally, I'd find his resting place but having a general location in the state would help. I suspect he's in northeast Mississippi, Corinth perhaps, but understand that, at the time of his death, his unit was part of Johnston's "relief" for Vicksburg that sat in Jackson for a while.
