I've pointed people to "Gods and Generals, "The Killer Angels, "The Last Full Measure", as a good place to read about the Civil War, they're good for people who don't read history books.
The movie "Gettysburg" is one of my favorite movies, OTOH "Gods and Generals" was a...disappointment.
I enjoyed Gods and Generals (loved Gettysburg). It seemed accurate and by comparison better than much else coming to the big screen. Do I understand correctly that we won't get the third in the trilogy, this, due to lack of enthusiasm for Gods and Generals?
A Civil War buff friend of mine made the same recommendation to me. I read them both and have to agree that they're a great place to start if one wants to begin a journey into Civil War history.
