… in arrows attacking each other or maybe an ambush of some sort or taking over another party to take power maybe and Smaby spear is involved very bloody would like to know more about this movie

I saw this movie on a premium channel like Showtime or HBO etc. it was probably about 15 years ago it was very violent in this Movie seen I remember there was a tribe of warriors attacking others and they were on horses they were using Bows arrow‘s, spears, there was a lot of blood in this Snowy scene like a takeover or some type of ambush battle, and it Had Like rocky areas or maybe flat planes covered in snow and it also was  shot In color, and was In English or it may have had subtitles? I don’t remember, The Warriors were on horses but I don’t remember if everybody who was Fighting had horses of their own, and weren’t your typical American actors that I remember, pretty sure they were Asian foreigners but not Indian Warriors. I also watch a lot of movies and I’m a movie buff myself but I can’t for the life of me remember this movie name or who starred in it just the scene that I can’t get out of my head and I’d like to put this puzzle together if somebody’s out there can help me do this I would appreciate it if any other details I’m thinking Of I will add it to this post thank you!
