Battle of Seleukeia Megale (294 BC)

The Battle of Seleukia Megale was the opening engagement of Ktesiphon Rebellion.

With the army still located in Syria following the First Seleukid-Antigonid War, Patrokles quickly gathered what forces were available to him to prevent the rebels from marching on the capital. While Patrokles was defeated in the field, his quick action and the significant casualties inflicted prevented the rebels from besieging the city.
