Battle of Mantinea (362 B.C.)
In the last of the police actions taken in the Peloponnesus by the Thebans, the Theban general Epaminondas reached Mantinea and faced off with a coalition of troops from Sparta, Athens, Elis, and various Arcadian cities. The battle involved more than fifty thousand combatants in all, an unusually large number for a fight among Greeks. Epaminondas utilized the same oblique (slanted) formation he had at Leuctra. But this time the maneuver was not as devastating and the encounter ended in a draw. According to Xenophon, “Both sides claimed the victory, but it cannot be said that with regard to the accession of new territory, or cities, or power either side was any better off after the battle than before it.” (Hellenica 7.5.27) One definitely decisive aspect of the battle was that Epaminondas, Thebes's most capable leader, was killed.
