I just found in my local library a very good book about civil war tactics. It is called "the Bloody Crucible of Courage" by Brent Nosworthy. It explains Napoleonic tactics tried in the early going and explains how the rifled musket chaged things. I think that if you read it you will have a better understanding of the battles you can't control.......It also describes artillery tactics and the rise of the Ironclad.
