The criteria is not whether or not they were wanted. That's not relevant. The criteria from the OP is whether or not any Confederate officer ever mentioned black soldiers under his command in the OR. David Twiggs was a Confederate Major-General, in command at New Orleans and overseeing the Louisiana Militia and Home Guard, both of which were "citizen soldiers" as militia are, i.e. "a military force that is raised from the civil population to supplement a regular army in an emergency".And it specifically tell us that their service was not wanted.
And it don't use the term "soldiers " but call them colored citizens.
