Overview
The Battle of Carrhae, also known as the Battle of Callinicum, took place in 296 or 297, after the invasion of Mesopotamia and Armenia by the Sasanian king Narseh. The battle took place between Carrhae (Harran) and Callinicum (al-Raqqah) and was a victory for the Sasanians. Narseh attacked with forces recruited from the Euphrates frontier. He managed to defeat his opponent by good timing.
Galerius and Tiridates III of Armenia escaped with a remnant of their forces. Galerius met Diocletian in Antioch. Eutropius and Theophanes the Confessor have recorded versions of a celebrated story regarding a public humiliation of Galerius by Diocletian, though the latter retained Galerius in command.
Diocletian later sent reinforcements for Galerius, and the latter managed to defeat the Sassanids two years later at the Battle of Satala.
Roman Campaign
During 296, a war ignited between Sasanian Persia and the Roman Empire. Shah Narseh who led the Sasanian’s invaded Rome’s state in west Armenia. This conquest leads on to Mesopotamia and Orhoene. However, despite the countless victories over the Roman's, Narseh halted further conquest.
