Battle of Callinicum

The Battle of Callinicum took place Easter day, 19 April 531, between the armies of the Eastern Roman Empire under Belisarius and the Sassanid Persians under Azarethes. After a defeat at the Battle of Dara, the Sassanids moved to invade Syria in an attempt to turn the tide of the war. Belisarius' rapid response foiled the plan, and his troops pushed the Persians out of Syria through skillful maneuvering before forcing a battle.
