A lot of those horses didn't make it out un-injured.

Laws have changed now, but perhaps back then they were different, especially in a different country.
That's true, trip wires were very common. And, I don't know how they do it now, but I don't see how they can train horses to run in a group at full speed and suddenly fall, one after the other. It looks like very painful falling, too! I saw a movie a couple months ago, "The Missing", and I was cringing at what some of those poor horses appeared to go through.
