Barry Morse would soon be cast as Lt. Phillip Gerard in The Fugitive.
Shiloh Degnan, the title subject of this episode, doesn't appear on camera until 46 minutes into the proceedings.
The character of Shiloh Degnan appears to be loosely based on George Armstrong Custer.
This episode takes place in 1869 or later because it's mentioned in the dialogue that Ulysses S. Grant (who took office that year) is President of the United States.
Hale: You don't think much of Shiloh Degnan, huh?
Wooster: You want an honest answer--I don't.
Galloway: (about Marriott) He got ten more days than I thought he had.
Hale: General, I haven't had a drink before breakfast in so long I can't remember. I could use one right now.
General: I shouldn't have to point out to you, Chris, that you don't smash the career of a great fighting man with fever dreams or guess work.
General: How well did you know Colonel Degnan, Chris?
Hale: Maybe better than you did, General.
Fogarty: (about Degnan) He had courage all right. I'll give him that. I won't give him much else.
Nancy Gates' character is billed as "Louise Marriott" in the ending credits but referred to as "Louisa" in the dialogue.
Nitpick: The first name of Fogarty, the alcoholic reporter, is never given in the dialogue.
