The battle of Leabel was a battle that took place between the Boeotia League led by Thebes against Sparta. Thebes victory against Sparta from Sparta's dominance in politics based on Sparta's powerful 'military power'.The Boeotia League victory itself lies in the use of a new formation by Epaminondas, one of the six Boeotarkhos (pl Boeotarkhoi). Epaminondas who was leading the Thebes rebellion and also the originator of the formation of Hieros Lokhos became the hero of Thebes. An idealist and liberator, Epaminondas brought Thebes to its peak. His influence also changed the political climate of Greece, albeit temporarily.The beginning of the battleA total of 10,000 Spartan troops met the Boeotian army in Leuctra which required 6,000-9,000 people after Sparta overcame Creucis Castle. Spartan troops led by Cleombrotus I started a battle with throws of javelins, catapults and arrows. They successfully restore boeotia salaries are reluctant to fight.Epaminondas chose a strange strategy. Instead of arranging his troops according to tradition, by placing his elite army on the right wing, which means direct contact with the hippeis, the elite Sparta army that has about 300 people.With the withdrawal of the Boeotian army, Thebes army became stronger as their numbers increased. Thebes defeated the Spartan cavalry and eliminated Cleombrotus's attempt to round the left wing of Thebes.Epaminondas attacks gradually. He placed his cavalry left wing and the Hieros Lokhos army led by Pelopidas set out first, against the right wing of Sparta. The rest departs gradually, with the rear left wing, arranging the diameter of the diagonal.Thebes with its right wing were composed of the cavalry and the Hieros Lokhos army composed of fifty men, thus succeeding in penetrating the Spartan right wing consisting of twelve columns of columns. Hit back, losses suffered reached 1,000 people including 400 most experienced soldiers and Cleombrotus.This battle shows the innovation and development of tactics that defeated traditional formations. By throwing a million left-wing columns, Thebes soldiers could produce enough power to erode Sparta's rightwing. On the other hand, Sparta can win if they concentrate attacks on the weaker parts of the Thebes army. With a diagonal array of Thebes troops also follow the battle line so that it troubles the Spartan army. And because of the inequality of the army in Sparta itself the troops easily fell when their elite power fell
