The Battle of Naupactus was a naval battle in the Peloponnesian War. The battle, which took place a week after the Athenian victory at Rhium, set an Athenian fleet of twenty ships, commanded by Phormio, against a Peloponnesian fleet of seventy-seven ships, commanded by Cnemus. In the battle, the Peloponnesians drew the Athenians out from their anchorage at Antirrhium by sailing into the Gulf of Corinth, moving as if to attack the vital Athenian base at Naupactus. The Athenians were forced to shadow their movements, sailing eastward along the northern shore of the gulf. Attacking suddenly, the Peloponnesians drove nine Athenian ships ashore and pursued the others towards Naupactus; victory seemed securely in their hands. At the entrance to the harbor of Naupactus, however, the last Athenian ship to reach the harbor turned the tide by circling around an anchored merchant ship to ram and sink its leading pursuer. Confusion set in among the Peloponnesians, and the newly emboldened Athenians set out after them and routed them. In all, the Athenians recaptured all but one of their nine grounded ships and seized six Peloponnesian ships. This surprising victory preserved Athens' naval dominance and kept Naupactus secure; the arrival of an additional twenty Athenian ships shortly afterwards secured the victory and put an end to Sparta's attempt to take the offensive in the Northwest.
