Battle of Oenophyta in the context of Battle of Tanagra (457 BC)

The First Peloponnesian War (460–445 BC) was fought between Sparta as the leaders of the Peloponnesian League and Sparta's other allies, most notably Thebes, and the Delian League led by Athens with support from Argos. This war consisted of a series of conflicts and minor wars, such as the Second Sacred War. There were several causes for the war including the building of the Athenian long walls, Megara's defection and the envy and concern felt by Sparta at the growth of the Athenian Empire.

The First Peloponnesian War began in 460 BC with the Battle of Oenoe, where Spartan forces were defeated by those of Athenian-Argive alliance. At first the Athenians had the better of the fighting, winning the naval engagements using their superior fleet. They also had the better of the fighting on land, until 457 BC when the Spartans and their allies defeated the Athenian army at Tanagra. The Athenians, however, counterattacked and scored a crushing victory over the Boeotians at the Battle of Oenophyta and followed this victory up by conquering all of Boeotia except for Thebes.

Myronides (Ancient Greek: Μυρωνίδης) was an Athenian general of the First Peloponnesian War. In 458 BC he defeated the Corinthians at Megara and then in 457 BC he defeated the Boeotians at the Battle of Oenophyta using a clever stratagem. Myronides' victory at Oenophyta led to a decade of Athenian domination over Boeotia, Locris and Phocis sometimes called the Athenian 'Land Empire'.

It has been debated, but it is unlikely he was the same Myronides who was sent to Sparta with Cimon and Xanthippus and who served as general at the Battle of Plataea.

Oinofyta (Greek: Οινόφυτα) is a village and former municipality in eastern Boeotia, Greece. Following the local government reform of 2011, it is now part of the municipality of Tanagra, of which it is a municipal unit. It was formerly named Staniates (Στανιάτες) until 1927.Within the territory of the municipal unit lies the ancient town of Oenophyta, where the Battle of Oenophyta was fought in 457 BCE.
