The Guns of Fort Petticoat

I wonder why no one who commented on this movie before noticed how this is the sort of scenario that made El Alamo the thrilling film it was, and that led to so many re-makes. There is a surrounded group, with no escape, and decided not to surrender to a bitter enemy... That this group was of women only, and that they died battling with bravery, makes me wonder where the cable televisions are, what video producer will discover this gem first - a gem it is, as people who saw this film only had praise for it! I'll be the first to buy a VHS or DVD copy of this film. Just tell me where it is.
