Does anyone know Black Beauty?

It's a cowboy movie about wild horses. The only thing I remember is the name of the mare " Black Beauty " and the last scene of the movie that haunted me since my childhood.
I did a research about it and find out a movie adopted from a novel " Black Beauty " but with different versions. I read about the many versions but couldn't figure out the one I'm looking for.
Black Beauty in the end is besieged on the cliff and she comitted suicide?
So do u know the movie ?
Regards

I'm only familiar with adaptations of Anna Sewell's novel "Black Beauty", about the life and times of a British horse (in a few words haha).

Do you know when it was made? I have a fairly substantial knowledge of horse movies, but I've never encountered another Black Beauty.
