Answer:
When he is less than two years old, Beauty observes the hunt pass by. He sees the hare's violent death and the serious injuries of two horses and one man. Some of the horses say it serves the men right, but Duchess disagrees. She claims she never understood why men hunt, for "they often hurt themselves, often spoil good horses, and tear up the fields, and all for a hare or a fox, or a stag, that they could get more easily some other way." But, she continues, "we are only horses, and don't know." They learn the injured man is Squire Gordon's only son, George Gordon, and he is very seriously hurt. The black horse that was injured has broken his leg and is shot to put him out of his misery. Beauty's mother is saddened by this death, saying the horse was one she knew, a good one named Rob Roy. Later Beauty observes the funeral for Squire Gordon's son, who also has died of his injuries.
