This detailed new study explores the battle of Leuctra and the tactics that ultimately led to the complete defeat of Sparta, and freed Greece from domination by Sparta in a single afternoon.The battle of Leuctra, fought in early July in 371 BC was one of the most important battles ever to be fought in the ancient world. Not only did it see the destruction of the Spartan dominance of Greece, it also introduced several tactical innovations which are still studied and emulated to this day. Sparta's hegemony of Greece (which had been in effect since the Persian wars of 480-79 and especially since the Peloponnesian War in 431–404 BC) was wiped away in a single day of destruction. Sparta would never recover from the losses in manpower which were suffered at Leuctra. Sparta's defeat created a power vacuum in Greece which several states attempted to fill (the Theban Hegemony and the resurgence of Athens) and gave rise to the dominance of Macedon in the 350s when Macedon would conquer Greece in 338 BC at the battle of Chaeronea. None of this would have been possible without the events at Leuctra. The Theban phalanx at Leuctra, with its great depth of 50 ranks, introduced new tactical thinking in Greek warfare and this thinking eventually led to the Macedonian phalanx of Philip and Alexander which conquered Greece and the Persian Empire less than 40 years later. The Theban commander at Leuctra, Epaminondas, also introduced the idea of drawing up his forces in echelon and fighting with a refused flank – something Alexander emulated in all of his major battles and which has been attempted at countless battles since.The importance of the battle of Leuctra cannot be underestimated. This superbly illustrated title gives the reader a detailed understanding of this epic clash of forces, what led to it, its commanders, sources, and the consequences it had for future civilizations.
