Livy mentions a troop of horse in the Numidian army, in which each soldier was supplied with a couple of horses, and in the heat of battle, and when clad in armor, would leap with the greatest ease and celerity from a horse which was tired or disabled, upon the back of the horse which was still sound and fresh.
Livy notes an unusual feature of the Numidian army's cavalry, where every warrior was equipped with several horses, enabling effortless jumping onto a fresh horse during intense combat when riding a tired one.
