Tiridates I of Armenia - War With Rome

War With Rome

For more details on this topic, see Roman-Parthian War of 58–63.

Unhappy with the growing Parthian influence at their doorstep, Roman Emperor Nero sent General Corbulo with a large army to the east in order to restore Roman client kings. A Hasmonean named Aristobulus was given Lesser Armenia (Nicopolis and Satala) and Sohaemus of Emesa received Armenia Sophene. In the spring of 58, Corbulo entered Greater Armenia from Cappadocia and advanced towards Artaxata, while Parasmanes I of Iberia attacked from the north, and Antiochus IV of Commagene attacked from the southwest. Supported by his brother, Tiridates I sent flying columns to raid the Romans far and wide. Corbulo retaliated using the same tactics and the use of the Moschoi tribes who raided outlying regions of Armenia. Tiridates I fled from the capital, and Corbulo burned Artaxata to the ground. In the summer, Corbulo began moving towards Tigranocerta through rough terrain and passing through the Taronitida (Taron), where several of his commanders died in an ambush by the Armenian resistance; however, the city opened its doors, with the exception of one of the citadels, which was destroyed in the ensuing assault. By this time the majority of Armenians had abandoned resistance and accepted the prince favored by Rome.

Nero gave the crown to the last royal descendant of the Kings of Cappadocia, the grandson of Glaphyra (daughter of Archelaus of Cappadocia) and Alexander of Judea (the brother of Herod Archelaus and the son of Herod the Great), who assumed the Armenian name Tigranes (his uncle was Tigranes V). His son, named Gaius Julius Alexander, married Iotapa, the daughter of Antiochus IV of Commagene and was made King of Cilicia. Nero was hailed vigorously in public for this initial victory and Corbulo was appointed governor of Syria as a reward. A guard of 1000 legionary soldiers, three auxiliary cohorts and two wings of horses were allotted to Tigranes in order to defend the country. Border districts were bestowed to Roman allies that assisted Corbulo including Polemon, Parasmanes, Aristobolus and Antiochus.

Vologases I was infuriated by the fact that an alien now sat on the Armenian throne but hesitated to reinstate his brother as he was engaged in a conflict with the Hyrcanians who were revolting. Tigranes invaded the Kingdom of Adiabene and deposed its King Monobazes in 61, who was a vassal of Parthians.

Vologases I considered this an act of aggression from Rome and started a campaign to restore Tiridates I to the Armenian throne. He placed under the command of spahbod Moneses a well-disciplined force of cataphracts along with Adiabenian auxiliaries and ordered him to expel Tigranes from Armenia. Having quelled the Hyrcanian revolt, Vologases I gathered the strength of his dominions and embarked toward Armenia. Corbulo, having been informed of the impending attack, sent two legions under the commands of Verulanus Severus and Vettius Bolanus to the assistance of Tigranes with secret directions that they should act with caution rather than vigour. He also dispatched a message to Nero, urging him to send a second commander with the explicit purpose of defending Armenia as Syria was now also in peril. Corbulo placed the remainder of the legions on the banks of the Euphrates and armed irregular troops of the nearby provinces. Since the region was deficient in water, he erected forts over the fountains and concealed the rivulets by heaping sand over them.

Moneses marched towards Tigranocerta but failed to break the defense of the city walls as his troops were unfit for a long siege. Corbulo, although eminently successful thought it prudent to use his good fortune with moderation. He sent a Roman centurion by the name of Casperius to the camp of Vologases I in Nisibis located 37 miles (60 km) from Tigranocerta with the demand to raise the siege. Because of a recent locust storm and the scarcity of fodder for his horses Vologases I agreed to raise the siege of Tigranocerta and petitioned to be granted Armenia in order to achieve a firm peace. Vologases I demanded that both the Roman and Parthian troops should evacuate Armenia, that Tigranes should be dethroned, and that the position of Tiridates I be recognized. The Roman government declined to accede to these arrangements and sent Lucius Caesennius Paetus, governor of Cappadocia, to settle the question by bringing Armenia under direct Roman administration.

Paetus was an incapable commander and suffered a humiliating defeat at the Battle of Rhandeia in 62, losing the legions of XII Fulminata commanded by Calvisius Sabinus and IIII Scythica commanded by Funisulanus Vettonianus. The command of the troops was returned to Corbulo, who the following year led a strong army into Melitene and beyond into Armenia, eliminating all of the regional governors he suspected were pro-Parthian. Finally in Rhandeia, Corbulo and Tiridates I met to make a peace agreement. The location of Rhandeia suited both Tiridates I and Corbulo. It appealed to Tiridates I because that is where his army had beaten the Romans and sent them away under a capitulation; on the other hand, it appealed to Corbulo because he was about to wipe out the ill repute earned before in the same location. When Tiridates I arrived at the Roman camp he took off his royal diadem and placed it on the ground near a statue of Nero, agreeing to receive it back only from Nero in Rome. Tiridates I was recognized as the vassal king of Armenia; a Roman garrison would remain in the country permanently, in Sophene while Artaxata would be reconstructed. Corbulo left his son-in-law Annius Vinicianus to accompany Tiridates I to Rome in order to attest his own fidelity to Nero.
