Battle of Hysiae (417 BC)

The Spartan king Agis II invaded Argive territory after a pro-Spartan faction at Argos was evicted by an Athenian force under Alcibiades, whose mission was to establish democracy there. Agis did not manage to take the city of Argos but destroyed the walls that the Argives had begun to extend towards the sea. He then captured and destroyed the town and fortress of Hysiae and had its male population executed. The campaign is described by the historians Thucydides (5.83.2), who actually fought in the war, and Diodorus Siculus (12.81.1), who wrote in the 1st century BC, over two hundred years later. Thucydides says that the Spartans marched against Argos in the winter of 418–417 BC with all their allies, but failed to take the city of Argos. The Spartans did, however, capture and destroy the Argive town of Hysiae, taking all the male citizens as hostages. The hostages were subsequently killed. ==Aftermath==

With Hysiae destroyed, the Spartans left a garrison in Orneae and left the territory. In response, Athens dispatched a force of 40 triremes and 1,200 hoplites who fought the Battle of Orneae to remove the garrison and take the city. == References ==
