Chuck, My 2nd great grandpa Samuel William Grimes (1844 Maury Co. TN - 1928 Obion Co., TN) was also "galvanized". The attached link will take you to a short biography about him that I posted on the Obion CO. TN genealogy web site. He served in the 3rd TN Inf CSA (Clack's) from May 1861 to October 1864 and joined the 2nd US Volunteer Infantry as a POW at Rock Island. I was lucky that his record contained decent info about his service (detached as a teamster and herdsman), but even luckier that his record referenced a pension inquiry. With that number I was able to find out that he was pensioned twice by the US Gov't, first as an invalid due to injuries caused by a wagon rollling over, then sometime after the gov't revoked his pension because of concern that his injuries were from Confederate service, he applied for and was granted an Indian Wars pension. If I remember correctly, there was a requirement for a certain period of time to be involved in active operations against the Indians of the region... It might be worthwhile to try to find out if he received an Invalid or Indian War pension. If he did you may find some decent info there. Good luck, Dave in Michigan.
