An All-Around Mounted Warrior
The 6th-century [C.E. Byzantine] soldier was in fact much more than a cavalryman: he had become an all-around mounted warrior. With his bow he could skirmish at a distance, but he was also heavily armoured and well equipped for close mounted combat. When a steady force was needed to hold ground, he was quite happy to dismount and fight as a heavy infantryman. On many occasions Belisarius took only cavalrymen with him, and when Narses needed steady infantry, he dismounted his cavalry.
