Continuity mistake: In the sequence entitled "A mother's gift to the cause, three sons off for the war".During the scenes in the house where the women are bidding farewell to the departing soldiers, the officers' sabers are on their left sides, as they should be. But, when Ben Cameron takes his leave of his family on the porch, the film has been flipped so that his saber appears to be on his right side. This flipped film continues as he mounts his horse from the right side (rather than the left, which is customary), draws his saber with his left hand, places it against his left shoulder, and rides away with the troops, all of whom appear to have their sabers in their left hands with their scabbards on their right hips. As the infantry passes by, the film is still flipped as the soldiers have their muskets on their left shoulders, and their bedrolls on their right shoulders; whereas, we had seen the same column of troops earlier with the equipment reversed, i.e., muskets on right shoulders and bedrolls on left shoulders.

Revealing mistake: When one of the female characters is putting on fine hermine for the little colonel's homecoming party, a black female servant is standing next to her - played by a white woman with black make-up on. You can see that the lower part of her neck is white.
Continuity mistake: On the food train, the close-up and far-away shots vary greatly as to types and quantities of food. (00:49:40)
