Other mistake: When Jimmy Stewart talks to George Kennedy about the taking of his son as prisoner. Right after they look at the map. Look over the shoulder of Kennedy in next few frames. You can see a white vehicle move across the horizon under the mountains. Looks like a white van or truck. With a HD TV, you can even see the dust trail as the vehicle moves left across screen.

Starring: James Stewart, Doug McClure, Patrick Wayne, Glenn Corbett
Factual error: After the birth of the baby, James Stewart and "Doc" Witherspoon are discussing the course of the war. "Doc" relates that he has always lived in Virginia and that his son died at Gettysburg at Little Round Top. No Virginia regiments fought at Little Round Top - only Alabama, Texas, Georgia, and Arkansas regiments.
Jacob Anderson: I know how you feel about this war, Pa. I guess we more or less feel the same way, but I don't see how we can sit by and ignore it anymore. Now you say it's not our business, not our fight, but we're Virginians and I believe that anything that concerns Virginia concerns us.
