Greetings Cosmic Americans!
I was virtually thumbing through C-Span Civil War lectures and I came across novelist Jeff Shaara speaking about his father Michael Shaara's novel, Killer Angels. I do not believe that Shaara the younger is known for brevity (he speaks for over an hour) but he may offer some insights on his father's book that you will find interesting.
For many, Killer Angels and the film based on the novel: Gettysburg function as the definitive history of the battle. In terms of popular history and public memory, I believe that the novel is a must read. Though one should read it with a critical eye.
