When Jess Birdwell sends the children upstairs after mother Eliza retires to the barn, he says, "up stairs to bed, all of thee!" In Quaker dialect, the pronoun thee is used as the objective case of thou, and is used only when addressing an individual. He should have said, "up stairs to bed, all of you!".
When Jess places the butt of the rifle on the ground after letting the Confederate soldier go, the trigger is on the side closest to him in the long shot. In the close shot, the trigger is on the side of the rifle away from him.
