As a kid, this was one of my favorite series--helped me become a Civil War historian and author. Years ago, while researching a book about the battle of First Bull Run, I corresponded with a CW buff who had been a bit actor in Hollywood when this series was shot. One of its episodes covered Bull Run, and he wangled a role in it as a Union soldier retreating at battle's end. He was overjoyed when the director told him to ad lib a line in front of the camera. Knowing the battle turned on the capture of an artillery battery commanded by Captain James B. Ricketts, the actor blurted out: "Run! The Rebels are coming! They got Ricketts!" As soon as he said it he realized it sounded as if he was saying: "Run! The Rebels have beri-beri!" He was embarrassed beyond words--and very relieved when the episode was shown months later and he found his blunder had been dubbed out!
