If I'm not mistaken, this appeared in the Memphis Daily Appeal, Sept 30, 1862, as part of an effort by Gen. Benjamin Butler to reorganize the Native Guards under the U S flag. The article appears in other Northern papers as part of a campaign to support Federal recruitment of former slaves and free men of color. The idea is, if a Confederate governor could do this, and if former Democratic Governor Benjamin Butler supports it, well then, we can do it, too!
I would like to see it in a New Orleans paper to learn more about how the appeal was presented to the public.
Note that Governor Moore's message recognizes that the LNG have been out of service since Feb 15th. Also, by late March it had become obvious that a Federal attack on New Orleans wold be made at an early date. Having sent off nearly all available Confederate troops and ordered his best Volunteer militia to Johnston at Corinth MS, Moore desperately needed experienced units like the LNG to defend the city. It is not clear how or when the LNG responded to the Governor's extra-legal appeal.
Based on an official notice placed by General Lewis, it is not clear that the LNG would have been accepted had they reorganized. New Orleans Bee, Mar 29, 1862, col 5:
HEADQUARTERS LOUISIANA TROOPS.
Major-General's Office, New Orleans, March 30, 1862. General Orders No 91
I. General Orders No 10 from these Headquarters calling for Volunteer companies for State service, some from the country have reported with fewer members than required by law, and partially armed, others without arms at all, and all were in consequence refused.
II. In order to prevent a reoccurance in future of a similar infraction to the above orders, no Volunteer company will be accepted on any account for State service unless fully organized according to the law and armed either with muskets, rifles or shotguns in good order.
