Cause → Event → Consequence
Following the Sasanian capture of Antioch, Shapur I turned his forces toward Dura-Europos, an important Roman trading center in Syria. The city's strategic position along trade routes made it a significant target in the Sasanian campaign against Roman eastern territories.
In 256 CE, Sasanian forces under Shapur I besieged Dura-Europos, employing diverse siege warfare techniques against a determined mixed Roman garrison composed of Cohors XX Palmyrenorum, vexillations from multiple legions, and other cohorts. Archaeological evidence reveals the dramatic and ultimately successful Sasanian assault on the city's defenses.
Dura-Europos fell to the Sasanians and remained in their hands for a period before being permanently abandoned. The site's exceptional preservation yielded rich archaeological evidence of Roman military presence and ancient siege methods, making it one of the most informative archaeological records of third-century Roman frontier warfare.
