Megalopolis (Wars of the Achæan League).

Fought B.C. 226, between the Spartans, under Cleomenes, and the forces of the Achæan League, under Aratus. The Achæans early gained an advantage, and the Spartans fled, pursued by the light troops. These, however, being unsupported, the Spartans turned and routed them, and then overwhelmed the Achæan hoplites in their turn with enormous slaughter.
