Battle of Naupactus - Aftermath

Aftermath

The Athenian victory at Naupactus put an end to Sparta's attempt to challenge Athens in the Corinthian gulf and the Northwest, and secured Athens' dominance at sea. At Naupactus, the Athenians' backs had been against the wall; a defeat there would have lost Athens its foothold in the Corinthian gulf and encouraged the Peloponnesians to attempt further aggressive operations at sea. In 428 BC, the Spartans would be so cowed by the memory of their defeats at Phormio's hands that they sent no aid to Athens' rebellious subject Mytilene in that year. In 427, when they finally did send a fleet, the commander was so afraid of being caught at sea by the Athenians that he fled home without accomplishing anything.
