I only saw the 20 minutes or so I described in the title, but it looked interesting. Searching reveals lots of movies about the civil war, but as far as I could tell it wasn’t really part of the story except as the reason the husband left.
It looked like a 90s movie, or possibly a 2000s TV movie. I didn’t recognize any actors, but I’m bad at that so I can’t assume the wife wasn’t super famous.
Wow, excellent job! I did not guess the age of the movie at all! Thank you very much.
