The Athenians rebounded well after their defeat at Tanagra, by sending an army under Myronides to attack Boeotia. The Boeotian army gave battle to the Athenians at Oenophyta. The Athenians scored a crushing victory which led to the Athenians conquering all of Boeotia except for Thebes, as well as Phocis and Locris. The Athenians pulled down Tanagra's fortifications and took the hundred richest citizens of Locris and made them hostages. The Athenians also took this chance to complete the construction of their long walls.
