Firstly, the Confederate states produced more than enough food to support the army. The data from the 1860 census leaved no doubt of that. Farmers were taxed in kind a percentage of the crop. No money exchanged hands. The incompetence of the commissary officials, root, stem & branch beggars belief. Mountains of taxes in kind gathered from farmers rotted at rail junctions. It didn't take much of that to dampen the farmer's enthusiasm. Due to dim wits CSA armies starved in the midst of plenty.
