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.
According to Livy, the Numidian army employed an innovative tactic involving multiple horses for each soldier. This allowed them to swiftly dismount from a worn-out horse and mount a fresh one in the heat of battle.
