I should have anticipated the question. While it's not a document I've actually seen, the reference to General Order (or G.O.) 70 appearing in service files of regimental commissaries. Evidently some went home when their commissions were vacated. Others sought new commissions as brigade or post commissaries.
In similar fashion the position of regimental quartermaster was abolished in September 1864. I don't recall the authority for that action. Legislation to authorize the office of ensign passed Congress on Feb. 17, 1864. Nominations required by law provides good background information for the soldier's career and appears in almost every service file for enlisted men nominated.
A nomination sometimes provides good information for the regimental battleflag. In this case Major Knox writes, "For more than two years this Regiment has had no color sergeant -- indeed for the greater part of that time had no colors." Knox's nomination is dated May 4, 1864. He must mean that the 1st Alabama lost its flag when the command surrendered at Island Ten, Apr. 8, 1862, and a new flag only recently replaced it.
The lost flag was recently returned to Alabama.
