Were officers like A P Hill and Dick Ewell unfit for duty, in the case of Hill for example he had an illness which appears to have been slowing killing him. Then you have Ewell who lost two limbs, these of course are not the only cases. I know the question is who would be the replacement but should untested officers been given the chance. Were unfit for duty officers kept on because they were a familiar face, part of an army commanders comfort zone you might say.
