War horses during the middle ages came from the local farms. Horses loaded with full armor carrying a man in full armor would have been too big and too heavy to execute the moves taught in classical dressage. The idea was to overpower by brute force and not agility.
When warfare turned to guns and swords and not just swords and brute force, the horse became a vehicle to use for offense and for defense. The original dressage horses (think Andalusians and Lusitanos and Lipizanners - all breeds derived from Arabians) were actually quite small compared to the knights' heavy horses (think Clydesdales and Shires and Percherons and Friesians) and also very small (running at about 15hh) compared to the aircraft carriers that dominate in the dressage arena today (who come in on the average at 16 hh to 17hh).
I have never seen the move you are referring to about the horse striking out with all four feet. That seems pretty impossible except in the cases of bronc horses, who are trained, believe it or not, to do just that - buck and carry on.
Are you referring to the capriolle - where the horse leaps up and kicks his two back feet out behind him, or maybe the courbette, where the horse is trained to stand low on his hind legs and jump towards the opponent? Both pretty intimidating moves if you're a mere foot soldier in Napolean's army, no?
BTW, I talked with my trainer regarding the horse in the original video - Martine - the story goes she is a very young horse who has been pushed to perform way beyond her years. Her trainers/owners struggle to keep this horse sound because she is being asked to do so much while her body is still growing. They demand so much from her because she is such a beautiful and extravagant mover - no argument there! In fact, not long after this particular performance, she went lame.
Did you notice the wringing tail? That is NOT a happy horse. That's a big F.U. in each swish.
Sorry to be such a know-it-all, but dressage is my riding passion!
To put it in perspective, my horse, while not as gifted in the movement department as 9-year-old Martine, but is certainly capable of the upper levels, is only a year younger than her. He has never been dead lame. Yes, we are only at 1st level right now, but there is so much to do in laying the foundation for the upper levels and I am OK with waiting. I got nothing but time!
Yes, I'm being a snob, and acting like I know better but good training takes years and years of two steps forward, three steps back. Not cramming a horse into a frame and repeatedly demanding something from an animal.
JMHO.
