Battle of Tanagra
Fought 457 B.C., between the Spartans, and their Peloponnesian allies, and about 14,000 Athenians and others, including a body of Thessalian cavalry. The battle was stubbornly contested, both sides losing heavily, but the desertion during the action of the Thessalians turned the scale, and the Spartans were victorious, though at a cost which deterred them from their intended attack upon Athens.
