This poem made me sad. How badly was the horse injured? Was it the end of its career? Its life? A broken leg could be both if it is bad enough. The way this scenario was presented is cold and impersonal it seems detached. At the same time it clings to a kind of rhythmic drama that stumbles and breaks as the horse and rider are injured. I really feel for them both they had high hopes that couldn't have been more violently dashed. It really is a sad poem with a coldly impersonal tone to it. It acts like it doesn't feel but it makes me feel a lot.
