Page "Delian League" Paragraph 7

The Allied fleet defeated the demoralized remnants of the Persian fleet in the Battle of Mycale — on the same day as Plataea, according to tradition.

This action marks the end of the Persian invasion, and the beginning of the next phase in the Greco-Persian wars, the Greek counterattack.

After Mycale, the Greek cities of Asia Minor again revolted, with the Persians now powerless to stop them.

The Allied fleet then sailed to the Thracian Chersonese, still held by the Persians, and besieged and captured the town of Sestos.

The following year, 478 BC, the Allies sent a force to capture the city of Byzantion ( modern day Istanbul ).

The siege was successful, but the behaviour of the Spartan general Pausanias alienated many of the Allies, and resulted in Pausanias's recall.
