In no uncertain terms, we have been discussing Confederate units. These are organizations accepted into service by Confederate authorities, officers commissioned by the Confederate War Department, and members paid by the Confederate government.
By Confederate law no command formed of Black men, free or slave, could have been accepted in service prior March 1865. Formation of any new units in Louisiana would have been quite difficult in part because War Department authorization had to have been granted before the government left Richmond on April 3, 1865.
What evidence do you have of a Black Confederate command in Louisiana of company size or larger?
