My daughter is a dressage practitioner. I thank you for the additional outside-the-box motivation...
What does your daughter ride? Hope she’s doing well with it. We’ve gotten a little too old and cheap to keep up with that.
But its’ interresting when you start looking at dressage movements as battlefield techniques. The canter pirouette wold allow you to strike quickly when surrounded by enemies while looking for an escape route. You could think of a piaffe as trampling on the bodies of your enemies. The various passage and half-pass forms will have obvious battlefield applications. And that was all true until the First World War and the advent of rapid-firing weapons.
