Please help me with this movie I saw on AMC or TMC?!

I don't know the name of it, but I can give a description of it!.

Set in the old west (I think)

A beautiful red headed woman, either in slavery or sold into it!.
The hero
Indians
A fort

A Scene: Red head tied up in an Indian Tepee!.
An Indian woman mad at the red headed woman because she thinks the red headed woman wants her husband (who is white, who is not the hero - who is shady)

A Scene: Out side the Tepee, still inside the Indian camp ground!.
The hero saves the red head from the Indians by using a compass and telling the chief that if the arrow moves away from him, bad things will happen!. He has the chief and the tribe all hold their axes to the compass!. The man and the red head escape down a river and pretend to go down a waterfall!.

Another Scene: The hero escaping from the fort jail and being helped by the Indian woman!. She gets shot by pretending to be the hero escaping!.

Another Scene: Later the hero saves the fort being attacked by the Indians by pretending he has an army except that the army are all corpses!. ( I think they're all dead!.)

Another Scene: The Hero and the Shady man have a gun fight in the barn over the red head!. The shady man dies (I think)

In the end the hero marries the red head and she is freed from slavery!.

Anybody know the movie in question!?
