Battle of Spartolos
The Battle of Spartolos took place in 429 BC between Athens and the Chalcidian League and their allies, in the early part of the Peloponnesian War. The fall of Potidaea had not succeeded in quelling the rebellion against Athens in Chalcidice. To ensure a steady stream of imperial revenue and suppress additional local uprisings, the Athenians dispatched Xenophon (son of Euripides) with 2,000 hoplites and 200 cavalry to launch an attack on Spartolos. They destroyed the crops outside the city and began negotiating with pro-Athenian factions in Chalcidice, but the anti-Athenian factions asked for help from Olynthus. An army from Chalcidice, Spartolos, and Olynthus met the Athenians in battle, but their hoplites were defeated and they retreated to Spartolos.
