Forgotten Movie Title?

Hi everyone I can’t remember a movie title I saw a few years ago. I’ll try to give you as much information as I can remember.
It was a western movie, about a group of cowboys herding cattle to St Lewis along the way they run into some problems. Near the end of the movie they end up resting there cattle on someone else’s land, the land owner demands payment. They pay in order to avoid a shootout. On the same plot of land some Normans (or people alike) are planning on settling claiming its gods land. The land owner gives them till the next day to leave before he shoots them. The cowboys leave but the youngest of the group turns back to defend the Normans and is shortly followed by the rest of his posy. All the cowboys die in a shootout with the land owner and his men apart from the youngest and as the credits roll I think it shows a photo of all the cowboys.
Thank you for your help.
