Not only that, but Louisiana quickly changed their militia law, specifying that it would be composed of white citizens.
10 months is quickly?
The legislatures reorganization of the militia also affected the Native Guards. Because the new statute specified white males and disbanded all existing militia units as of February 15, 1862, the Native Guards ceased to exist on that date. Their demise was temporary, however, for Governor Moore reinstated the Native Guards on March 24 after the Federal navy under Captain David G. Farragut entered the Mississippi River. (Link)
Apparently, Governor Moore didn't get the message. The Louisiana Native Guards were abolished for only about 5 weeks.
