Second Battle of Herakleia Media (277 BC)

The second battle of Herekleia Media occured in the autumn of 277 BC, a few short months after an earlier battle at the same location.

Ashushur-Bêlshunu, the satrap of Adiabene, had orgininally marched his army south on the Seleukid capital of Seleukeia Megala, but a force of Greek mercenaries hired by the citizens of Seleukeia prevented him from marching on the capital. Instead he turned north, his capital having been sacked earlier by Antiochos, to the poorly protected Median lands. The Greek mercenaries, now under the pay of Antiochos, turned north to chase them and caught them at the town of Herakleia Media.
