When the battle starts get on the high ground. If you see dynamite exploding near you then you're in the right place. Go to the edge and look for Hollister in the trench. When you see him throw dynamite at him until you run out or he moves. Watch out because when he moves he is usually going to the high ground where you are. When he gets on the high ground find him and go into quickdraw. Try and put as many bullets in his his head as possible before quickdraw runs out. When quickdraw does run out simply shoot him with your rifle. When the cutscene plays you're almost done. After it plays simply find Hollister on your radar. Then run to him and shoot him until he explodes.
