The vertical stirrup leather may be one of the most identifiable elements of the traditional Military Seat. This principle applies the fundamental laws of physics. It is based on the rider's base of support in the irons being the most stable when the rider's feet are in the stirrup irons centered under the rider's body mass and the rider's body mass is aligned vertically in a balanced manner.

Riders were trained to maintain a vertical stirrup leather regardless of incidents that might disrupt their balance because keeping the feet under the rider;s body in distressing conditions allows the rider to regain a balanced riding position.

This picture shows an assortment of leg positions, however most riders have attempted to keep their legs under them. Note how some riders use their upper body to balance in a backward position in order to deal with the slope while other remain more centered in their balance. These are enlisted men, probably dragoons by the length of their rifles, who rode to battle and fought dismounted. Cavalrymen, particularly officers generally were better trained in horsemanship.

Keep in mind that many horses require the encouragement of a spur to maintain forward movement in difficult circumstances. I suspect here the rider has his feet back in order to spur his horse. Cavalrymen were know to reach back and grab hold of the dock in order to keep their upper body stable in slides of this extreme slope.

I have often thought that a great training device to teach the vertical stirrup leather principle would be to use the vertical/horizontal sensing function of a smart phone. The rider's smart phone would be placed in a vertical boot case.
A phone app would be turned on that would be programed by the developer to sense the rider's leg motion ahead or behind vertical vertical/horizontal function. If the rider's legs went ahead of vertical, the app would make a beep, beep, beep, beep sound telling the rider to move their leg back under them to the vertical position. If the rider's legs went behind vertical, the app would make a dong, dong, dong, dong sound telling the rider to move their leg forward under them to the vertical position. Anyone know how to program or develop and app?
