Toward the end, as Jed is carrying his wounded brother over his shoulder, Colonel Bella walks up with his gun ready... and lets them go.
Another heartwarming scene occurs shortly before that when Colonel Bella is writing a letter to his wife back home.
Colonel Bella: I can't remember what it was to be warm. It seems a thousand years since I was a small boy in the sun. How did I come to this high, desolate place where there is nothing but loneliness? So much is lost. I want to look into your eyes and forget. It all seems so far away: a warm house where my shadow never falls, your long, black hair in my hands. There is no more revolution; only you to come back to. I will post my resignation.
