Battle of Rhandeia

Paetus nonetheless appeared confident of victory, and followed the Parthian declaration of war and capture of Tigranocerta with his own invasion of Armenia, while Corbulo remained at Syria, further strengthening the fortifications in the Euphrates frontier. Paetus had only two RomanThe Roman Empire was the post-Republican period of ancient Rome. As a polity, it included large territorial holdings around the Mediterranean Sea in Europe, North Africa, and Western Asia, and was ruled by emperors. The first two centuries of the Roman Empire saw a period of unprecedented stability and prosperity known as the Pax Romana ('Roman Peace'). The Empire was later ruled by multiple emperors who shared control over the Western Roman Empire and the Eastern Roman Empire.Roman legions with him, IV Scythica and XII Fulminata, and advanced towards Tigranocerta. A few minor forts were taken, but a lack of supplies forced him to withdraw westwards for the winter.

The Parthians had originally intended to invade Syria, but Corbulo put on a convincing display of military might, building a strong flotilla of ships equipped with catapults and a bridge over the Euphrates, which allowed him to establish a foothold on the Parthian shore. Therefore, the Parthians abandoned their plans for Syria, and turned their attention towards Armenia. There, Paetus had dispersed his forces and granted extended leaves to his officers, so that he was taken unawares at the Parthian advance. Upon learning of it, he initially advanced to meet Vologases, but after a reconnaissance detachment was defeated, he panicked and withdrew hastily. Paetus sent his wife and son to safety in the fortress of Arsamosata, and tried to block the Parthian advance by occupying the passes of the Taurus mountains with detachments from his army. In so doing, however, he further dispersed his forces, which were then defeated in detail by the Parthians. Roman morale plunged and panic set in among the army, which was now besieged in a series of hastily erected camps near Rhandeia. Paetus, who appears to have fallen into desperate inactivity, sent urgent messages to Corbulo to come to his rescue.

Operations during the final years of the war: the raids of Tigranes into Parthian territory provoked a Parthian counterattack, which culminated in the surrender of the Roman army of L. Caesennius Paetus.

Corbulo in the meantime had been aware of the danger faced by his colleague, and put part of his forces on readiness; but he did not march to join Paetus, and some accused him of delaying in order to reap more glory from rescuing him. Nevertheless, when the calls for assistance arrived, he responded quickly and marched forth with half of the Syrian army, carrying many provisions laden on camels. He soon met dispersed men of Paetus' army, and managed to rally them around his force. But before he could arrive to the rescue, Paetus had capitulated: the Parthians, aware that relief was nearing, increasingly harassed the Romans, until Paetus was forced to send a letter to Vologases to seek terms. The subsequent treaty was humiliating: not only would the Romans leave Armenia and surrender all forts they held, but they also agreed to build a bridge over the nearby Arsanias river over which Vologases could pass in triumph, sitting atop an elephant. In addition, the Roman army was liberally plundered by the Armenians, who took even the Romans' weapons and clothes without facing any resistance. Still worse, according to rumors reported by Tacitus, the Romans were made to pass under the yoke, a gesture of ultimate humiliation in Roman eyes.

The two Roman forces met on the banks of the Euphrates near Melitene, amidst scenes of mutual grief; while Corbulo lamented the undoing of his achievements, Paetus tried to convince him to attempt to reverse the situation by invading Armenia. Corbulo however refused, claiming that he did not have the authority to do so, and that either way the army was too worn out to be able to campaign effectively. In the end, Paetus retired to Cappadocia and Corbulo to Syria, where he received envoys from Vologases, who demanded that he evacuate his bridgehead over the Euphrates. In turn, Corbulo demanded the Parthian evacuation of Armenia. Vologases agreed to this, and both sides withdrew their forces, leaving Armenia once again masterless but de facto under Parthian control, until a Parthian delegation could travel to Rome.

HISTORIC BATTLES

Roman–Parthian War (58–63 AD)

The Roman–Parthian War of 58–63 or the War of the Armenian Succession was fought between the Roman Empire and the Parthian Empire over control of Armenia, a vital buffer state between the two realms. Armenia had been a Roman client state since the days of Emperor Augustus, but in 52/53, the Parthians succeeded in installing their own candidate, Tiridates, on the Armenian throne. View Historic Battle »

Background: Ever since the expanding Roman Republic and the Parthian Empire had come into contact in the mid-1st century BC, there had been friction between the two great powers over the control of the various states lying between them.

Diplomatic maneuvers and preparations: Corbulo used this lull to restore his troops' discipline and combat readiness, which had diminished in the peaceful garrisons of the East.

Outbreak of the war — The Roman offensive: It was an inauspicious start for a campaign, and Corbulo severely punished the survivors and their commanders.

Fall of Artaxata: Terrified by this display of Roman might, several towns and villages surrendered, and the Romans prepared to move against the northern Armenian capital, Artaxata.

Fall of Tigranocerta: The Romans were now in control of Armenia, and they promptly installed its new king, Tigranes VI, the last descendant of the Cappadocian royal house, in Tigranocerta.

Parthian counterattack: In order to reinstall his brother on the Armenian throne, the Parthian king assembled a force of picked cavalry under Monaeses, complemented by infantry from Adiabene.

Parthian siege of Tigranocerta: Tigranes had taken care to gather supplies, and the city was well-fortified and garrisoned with Romans and Armenians alike.

Battle of Rhandeia: The Parthians had originally intended to invade Syria, but Corbulo put on a convincing display of military might, building a strong flotilla of ships equipped with catapults and a bridge over the Euphrates, which allowed him to establish a foothold on the Parthian shore.

Corbulo's return and peace settlement: Whatever illusions the Roman leadership had, they were shattered by the arrival of the Parthian delegation to Rome in the spring of 63.

Aftermath: Nero celebrated this peace as a major achievement: he was hailed as imperator and held a triumph, although no new territory had been won, and the peace reflected a compromise rather than a true victory.
