Actually, Homer is more correct and I only had part of it. I missed James' record in the 7th Prov EMM which clearly states he was captured and paroled on October 6. It doesn't state where, but it had to be during Shelby's raid, which was the only occasion in that area at that time wherein a PEMM officer would have been captured and released.
Did you notice in this record that it says in a muster role of his unit in February 1864 that he "died of disease, Nov. 6, 1863." This may have happened at home, because legally he couldn't have served on active duty with the PEMM until he was officially exchanged from his earlier capture and parole. That would have been a violation of the laws of war.
Shelby's raid moved rapidly to elude Union pursuers, so Simmons was captured somewhere along their line of march on October 6.
