Parthian Heavy grivpanvar knights appeared in many of the later Parthian and Sassanian battles, with one of the best-known encounters of the Parthian grivpanvar occurring at the
Battle of Nisibis in 217 against the Roman army of Emperor
Macrinus. According to the Roman historian
Herodian, the imperial Parthian army led by Emperor
Artabanus IV of Parthia, reformed many of their armies and units resulting in the emergence of a new force of camel mounted cataphracts (Camelphracts). The grivpanvar appear to have been used against the heavy
Roman legionaries. At dawn, the Parthians charged their heavily armored camels and grivpanvar cavalry into the Roman lines, but as they approached the Roman forces withdrew, leaving large numbers of
caltrops behind, with fatal results. The Parthians' horses and camels stepped onto these lethal weapons and fell, taking their riders with them thereby breaking the momentum of the charge. This vicious battle was the last Roman encounter with the Parthian grivpanvar.
Sassanian The Sassanians continued to use the grivpanvar in their armies, starting from the reign of
Ardashir I until the final ruler
Yazdegerd III lost his throne. One of the first deployments of Sassanian grivpanvar occurred at the
Battle of Edessa in 259 AD, where a powerful army of Sassanians led by the emperor
Shapur I came under assault from Roman sovereign
Valerian's soldiers, including the renowned and elite imperial
Praetorian Guard. During the battle, the relatively small 40,000-strong Sassanian army crushed a 70,000-strong Roman force. Although little is known of the battle, records show that the Sassanians used grivpanvar in their army along with lightly armed horse archers. After the battle, emperor Valerian and many other high-ranking officials were captured by Shapur. The result was an overwhelming Persian victory, with the entire Roman force slaughtered or captured in stark comparison to the minimal number of Persian casualties. The Sassanians used grivpanvar during
Shapur II's Arab campaign in 342 AD, when Shapur ordered his troops to destroy an Arab force that had attacked the southern borders of his empire. ==See also==
