How a strategic Spartan stronghold in Orneae fell to Athenian and Argive forces
In the winter of 417 BC, the Peloponnesian War shifted to the city of Orneae. Following their victory at Hysiae, the Spartans fortified this location to harass Argolis. However, a combined Athenian and Argive counter-offensive soon arrived, leading to a decisive storming of the city and the expulsion of the garrison.
The conflict at Orneae was a direct consequence of the earlier Battle of Hysiae. After the Spartans achieved a decisive victory and razed the stronghold at Hysiae, they turned their attention to Orneae. By fortifying this city and installing a garrison, the Spartans aimed to maintain a persistent threat against the region of Argolis. They further solidified their position by settling exiles from Argos within the city walls, intending for this base to serve as a launchpad for ongoing harassment.
The situation changed when the Athenians intervened to support their Argive allies. Recognizing the threat posed by the Spartan presence, Athens dispatched a significant force consisting of 40 triremes and 1,200 hoplites. This military commitment was intended to assist Argos in reclaiming the territory and removing the Spartan garrison that had been left behind after the main Spartan army withdrew from the area.
The subsequent engagement saw the Athenian and Argive forces take Orneae by storm. The operation was successful in its primary objectives: the Spartan garrison was expelled, and the city was captured. The fate of the Argive exiles who had been settled there by the Spartans was severe; some were executed during the assault, while the remainder were forced to flee the city entirely. This event marked a notable shift in the local power dynamics during this phase of the Peloponnesian War.
While the historical record provides a clear account of the tactical movements, the Battle of Orneae highlights the volatile nature of alliances and local strongholds during the Peloponnesian War. The rapid transition from Spartan control to an Athenian-backed recapture illustrates how quickly fortified positions could change hands, often at a high cost to those caught in the middle of these larger geopolitical struggles.
