If I was not clear, I was questioning why more army commanders were not developed, not just mid-level officers. Of course mid-level officers arose throughout the war, but it seems the number of army commanders was extremely limited because they kept on recycling the same guys. .
I get that some may think the there was a lack of senior leaders, but that is only because they were not developed. It would have been easy for Lincoln to go back to McClellan a third time after Fredericksburg, but he gave an untested Joe Hooker a chance. And when Hooker failed, he gave an untested Meade a shot. It just feels like the CSA, for some reason, did not do the same. if Davis had truly lost faith in Johnston he should have stuck by his guns and found someone else. And when that person failed don't go back to Johnston, but find someone else again. And I dont believe there were no talented generals who were worthy of a chance. Until they are put in the drivers seat you wont know what you have.
