Battle of Barbalissos

The battle was fought during the reign of Trebonianus Gallus between the Sasanian Persians and Romans at Barbalissos, an old Roman town near Aleppo in modern-day Syria and close to the Euphrates River. The battle was fought in 252 when Shapur I (239-270 AD), King of the Sasanian Empire led his army from the Euphrates River and met with a Roman army 60,000 strong of legionaries, archers, and Roman cavalry. Although the number of forces of the Sasanian army are unclear, through tactics and use of strategy Shapur I managed to win the battle and open a way through the Syrian cities and castles.^[7][8] Based on the place-names listed in the Res Gestae Divi Saporis, it has been suggested that Shapur leap-frogged the key fortresses of Dura Europos and Circesium at the Khabur confluence in order to bee-line towards a major Roman army at Barbalissos, perhaps under the legate of Syria or someone holding an extraordinary command to deal with the Sasanians.^[9] After annihilating this army, he split his army into two to neutralize the legionary bases of Raphanea and Zeugma, and perhaps to obfuscate his march on Antioch, which apparently took the locals by surprise. After taking Antioch, he then split his army into three our four forces to raid Syria and eastern Cilicia more widely, while another army raided Cappadocia and captured the legionary base at Satala. Meanwhile, a task force marching from Pirisabora appears to have captured Dura and Circesium, exploiting the fact that the Romans were distracted by the raids into Syria and Anatolia.^[10] The defeat was very costly for Valerian who appointed many more armies to stop Shapur I from quick advance into Roman soil and later decided to lead an army of 70,000 legionaries himself in what became known as the Battle of Edessa.^[11]
