Ron --

On April 8-9, 1865, the Army of Tennessee underwent reorganization under the recent law passed by Congress. I don't have particulars about it, but the same process took place in Forrest's cavalry corps during March 1865. Some regiments were consolidated into a single company; sometimes survivors of a company were assigned to different consolidated companies. In the end all new companies (and regiments) had about the same number of men actually present for duty on roll according to law.

New officers were elected, and officers left without a command designated supernummerary. I've not seen any documentation for this. My comments are based on review of Alabama service files.

For example, all the Alabama regiments of Scott's Brigade were consolidated as the 27th Alabama Regiment, it having the lowest numeric designation among regiments of that brigade. Final parole records of men from the old 27th, 35th, 49th, 55th and 57th Alabama are filed with the 27th Alabama Regiment. Since many rolls were lost, sometimes the only record of a man who enlisted late in the war will be found with the consolidated regiment. The parole record will include date and place of enlistment, so it's usually not difficult to determine which regiment and company a soldier originally joined.

1865 paroles issued in North Carolina are found on a separate National Archives microfilm collection.
