Following the fall of Potidaea, Athens sought to suppress ongoing rebellion in Chalcidice and secure imperial tribute. The Athenians dispatched Xenophon with 2,000 hoplites and 200 cavalry to attack Spartolos, destroy crops, and negotiate with pro-Athenian factions. Anti-Athenian factions in the region called on Olynthus for military support.
A combined force from Chalcidice, Spartolos, and Olynthus engaged the Athenians in open battle. Though the Chalcidian hoplites were initially defeated and retreated, their cavalry and peltasts overcame the Athenian troops. After reinforcements arrived from Olynthus, a second attack routed the Athenians, who could not effectively engage the enemy light infantry and horsemen.
The Athenian force was decisively routed, with all its generals and 430 other soldiers killed. The defeat left Athens unable to suppress the Chalcidian rebellion, and the tribute list of 429/8 BC shows that only a handful of Chalcidian cities—several of which had not even joined the Chalcidian League—remained in the Athenian tribute system.
