Alan, these are just educated guesses based on the information I have available. Southern personnel records are hardly complete, especially after 1863. J.T.'s muster rolls are extant up until early 1864, the last of which indicates his promotion from 1st sergeant to 2nd lieutenant. By the time J.T.'s listed as missing in the Battle of Allatoona Pass on Oct. 5 1864, he's still a 2nd Lt. In the battle report for Franklin, TN (Nov. 30, 1864), he is noted as having been among those from Sears' Brigade to reach the Federal earthworks; he is also listed as a lieutenant. Most of the subsequent records have a "1st" in front of "Lt" but this one does not. Mr. Beiser believed that J.T.'s collar in the photo indicates a rank of 1st lieutenant. Given the miserable conditions for the Army of Tennessee post-Franklin, I don't think it likely he got his picture taken after the battle. After leaving Florence, the army was rapidly on the move to try to cut off Schofield from Nashville. It's not known when J.T. was able to rejoin his command after Allatoona Pass, as Hood was still harassing Sherman. Decatur, AL remained in Union hands after the battle in late Oct. Since the Army of Tennessee languished for almost 3 weeks in the Tuscumbia/Florence area, it just seems to me most likely that the picture would have been taken there, if all the other information is valid.
