The plot thickens as regards Hobart. He was, evidently, paroled following his tenure as a POW - possibly in/near Richmond, possibly Libby Prison. He did, however, re-enlist and return to the fray, where he was wounded and captured again. There is correspondence from his father, Ferdinand, and the story on the General Lyon. I think that, given the multiplicity of names, there might be more than one in this mix.
