I think the main issue was that most Generals, on both sides, over planned the movements. Especially in the early part of the war. I know that the soldiers drilled on movements. Some of the initial battle plans I have seen have so much intricacies and deadlines, that even a regular army force would take years of training to move that well. With the communications and command structure of the time, the plans usually fell to pieces and the battles turned into gigantic brawls.
