The (second) battle of Mantinea, July 4, 362 BC: the final nail in the coffin of Spartan dominance. At the battle of Leuctra in 371 BC, a resurgent Thebes led by its great statesmen and tactician reformers Epaminondas and Pelopidas defeated the army of Sparta. The defeat was one of the greatest shocks Greece had witnessed - not only did the Thebans defeat the Spartans but the Spartans turned and fled from the battlefields - something they had not done before even in the face of defeat.
