Read this book many years ago (first published in 1987) the author was a known wargamer. I think this affects how I approached the book. It's not very academic and is an easy read. It doesn't resolve the issues it set's out to and I can see how it could upset out American cousins. However it does challenge and make you think. I think it's worth the time spent reading it especially if your a gamer. It will not give you a history of the war but will set you off wanting to find out more.
Dr Griffith painstakingly dismantles all of the preconceptions about the ACW using thorough research and contemporary accounts. He explains the nature of warfare on the American continent in the 1860s and shows that it was NOT the first "modern" war - but perhaps the last Napoleonic war?
Chapters include command and control, drill, the infantry firefight, cavalry and artillery plus others. All in all a superb work.
