If you've never seen it, The Horse Soldiers. Great? Dunno. Good solid film, though. Wayne liked it the best of all his work and he does a great job as the commander. William Holden is great as the acerbic MD who clashes with Wayne.
GWTW is not a Civil War film. It is a film about a person named Scarlett O'Hara, which happens to take place during the war and Reconstruction. There are cogent observations about both these events, but, as I see it, after around a dozen full viewings or more in my life (first seen by me on the big screen in 1969), the film is the tragedy of Scarlett, a vivacious, gorgeous, intelligent woman who could have found true happiness, but lost it all because she is too headstrong.
Cold Mountain is not a Civil War film (I read the book first), for similar reasons. It is a story of tragedy and noble sacrifice, the particulars of which are illuminated by the time period.
Glory and Gettysburg are spot on, excellent films and excellent stories. I read The Killer Angels (source for G-burg) in the '70s.
I've never seen G&G, but, as my longtime girlfriend said after she saw it, "It helps to like Stonewall Jackson - a lot."
Fess Parker, IIRC, starred in a film about the Union train-nappers who almost got away with it. Can't recall the title. Not bad.
Van Heflin in The Raid, about some Rebs robbing St. Albans, VT. They had to throw in the female lead/love interest, but otherwise, enjoyable.
The more often I see Shenandoah, the more I appreciate the depth of its moral complexities, which are not that readily apparent at first viewing. Worth re-watching, more than a few times. While we're here, I heartily recommend Stewart's post-WW2 work, especially his Westerns. Stewart is far, far, far from an 'aw-shucks good ole Jimmy Stewart' actor. Far, far, far. His characters are morally conflicted, not necessarily good or even likeable (his work in The Naked Spur is fantastic, Jimmy Stewart as borderline obsessed Crazy Guy).
For comedy, Glenn Ford in Advance to the Rear. Ford was a vastly underrated comic actor; very subtle, really; excelled as the straight man befuddled by the daffiness around him.
There's a couple of Civil War Out West films, very similar, about CSA PoWs being dragooned into the US service; one has Glenn Ford, I believe, and George Hamilton; the other has Joseph Cotten and Somebody Well Known whom I cannot recall.

(A) When in doubt, agree with Ace.
(B) Pull my reins up sharply when needed, for I am a spirited thoroughbred and forget to turn at the post sometimes.
