It may be time for the Guards to consider losing the double-bridle. These horses are constantly being ridden and held still by use of the curb bit. It takes years of practice for both horse and rider to use a double-bridle correctly. One only sees it nowadays at the higher levels of dressage. Constant reliance on the curb rein teaches the horse to resent it and the horse will protect its mouth by clamping down and resisting further eroding the utility of the bit and the reins. Most of them have already learned to ignore the constant scraping of the spurs against their sides. Shorten the shank, wear them where the heel meets the sole, turn them over, don’t wear at all, but do something.
That rain really triggered some of those horses, but those guards were amazing to keep control and stay aboard. The only casualty was the tossed helmet. Good to see the teamwork of the CofH, stable trooper and the guards who stayed back, for their colleague.
