Cavalry or horsemen were soldiers or warriors who fought mounted on horseback. Cavalry were historically the most mobile of the combat arms. An individual soldier in the cavalry is known by a number of designations such as cavalryman, horseman, dragoon or trooper.

Infantry who moved on horseback, but dismounted to fight on foot, were known in the 17th and early 18t
