This is an old discussion, but I only got onto this site a couple months back. My great great uncle William Carroll (W.C./akaCarroll) Minton served withB
the 22nd Regiment (Barteau's) and earlier with the 7th Battalion (Bennett's) He was at the battles at Reinzi (Rienzi), Monterey, and Courtland, as well as General Wheelers last raid into Tennesse. He was captured and paroled at Carthage, Tennessee.
There is a lot of informaton about the 22nd at the following sites (hope the URLs are still good):
