When you get his service record I think you might find a record of his capture and time as P.O.W. If so, please share that information with us. I'm betting he was sent to Rock Island Barracks in Illinois as a P.O.W. but that's only a guess.
If you have a photo of him or anything else you would be willing to share with us on the website or book project please let myself or Ron Skellie know. As mentioned earlier, if you have visited our website on the 7th Mississippi (link below) please do so. Let us know if we can help you in any way.
