I was beginning to think I imagined this show. I'm 47 and my older brothers and I have all recalled seeing a TV series where two brothers were on opposite sides of the American Civil War. We had thought it was called RALLY 'ROUND THE FLAG but could never find any mention of it in TV reference books. I don't recall toomuch about the show but yes, it would be a good show for some enterprising TV producer to re-do.
