It takes a large number of horses/mules to keep a field army of 100,000 supplied even with a railhead 10 miles away. I am not arguing that conscription is unconstitutional or without merit, my argument is that the elements that make conscription a positive did not exist in the CSA. Was secession a mistake yes, so was firing on Sumter and slavery is not just odious but a threat to public safety that said trial by combat was chosen.
