The Confederate Congress made several more amendments over the course of the war to address losses suffered in battle as well as the North's greater supply of manpower. In December 1863, they abolished the practice of allowing a rich drafted man to hire a substitute to take his place in the ranks. Substitution had also been practiced in the Northern states, leading to similar resentment from the lower classes. [17]
Challenges to the subsequent acts came before five state supreme courts; all five upheld them. [18]
