A movie about a tribe and a guy escaping

I think I watched it on TV around 10 years ago. I don’t remember much but what I do remember is this:
The guy’s tribe gets captured and then the enemies try to have some fun by letting go two prisoners at a time just to shoot them. When it’s his turn, the guy somehow escapes the assault of arrows and runs for his life. He got hit once but didn’t die from it. The guy runs into a pit full of dead bodies, gets scared and runs off. The enemies chase him. He runs into a jungle area and climbs into a tree. The enemies pass him, but a drop of his blood gets onto one of the enemies. They finally notice after a while and turn back.
Another scene I remember is that he returns to the civilization and declares his name. I remember that there was very little talking in the movie until that point.
