A great History book about the civil war is called "Killer Angels" By Michael Shaara. He's a Pulitzer Prize winner. Drop everything and buy it now! (The Best Civil War Book Ever)

There is an excellent, unabridged Audiobook version of Killer Angels that I HIGHLY recommend, especially if you are a commuter. It is not just read, but acted. The performer is very versatile and the thing just comes alive.

The Turner (yes, that Turner) production of Killer Angels is also excellent on DVD, if you can get beyond the laughably fake beards.

The movie version of Killer Angels is called simply "Gettysburg" and is perhaps 85% faithful to the book, and an extraordinarily authentic production (except for the aforementioned beards and some very fat Confederates here and there).
