Location of the Battle of Leuctra

The Battle of Leuctra (Ancient Greek: Λεῦκτρα, Ancient Greek: [lêu̯k.tra]) was fought on 6 July 371 BC between the Boeotians led by the Thebans, and the Spartans along with their allies. The battle occurred in the context of the King's Peace, or Peace of Antalcidas, which had ended the Corinthian War in 386 BC. The Peace was formally renewed in 375 BC, but a disagreement between the Spartans and the Thebans over the protocol for renewing the Peace again in 371 led directly to the battle, which took place in the vicinity of Leuctra, a village in Boeotia in the territory of Thespiae. The mainly Theban victory shattered Sparta's immense influence over the Greek peninsula, and the wider Aegean Greek world, which Sparta had gained with its victory in the Peloponnesian War a generation earlier.

Main article: Boeotian War

The Corinthian War, between Sparta and a Persian-backed coalition of Thebes, Athens, Corinth, Argos and other Greek allies, had ended in 387/6 BC with the King's Peace (also called the Peace of Antalcidas, or the Common Peace), under the terms of which the autonomy of all Greek cities not under Persian control was guaranteed. Sparta, as the guarantor of the King's Peace in Greece, immediately used this autonomy clause to force the Thebes-dominated Boeotian League to disband. In 382 BC, the Spartan general Phoebidas seized Thebes' acropolis, the Cadmea, thereby assisting the pro-Spartan Leontiades and his oligarchic supporters in taking control of Thebes, a clear violation of Theban autonomy.

In late 379 BC, an anti-Spartan Theban exile faction overthrew Leontiades, and immediately signaled their intent to reconstitute the Boeotian League by electing four of the leaders of their revolt as Boeotarchs, the traditional title of the leaders of the Boeotian League. This resulted in the Boeotian War in 378 BC, and Sparta's failed attempts to regain control of Thebes and Boeotia.

A short lived peace, was agreed to again in 375 BC, with renewed conflict in 373 BC. Throughout the Boeotian War, Thebes had continued to expand its dominance over Boeotia. It captured and severely damaged both Plataea, long an ally of Athens, and Thespiae, and forced their citizens into exile. By 371 BC, having engaged in costly naval campaigns, both Sparta and Thebes' ally Athens, were ready for peace. Thebes, faced with the prospect of fighting Sparta alone, was likewise prepared to agree to a new peace treaty, which, like those of 386 and 375, promised the independence of all Greek cities. When it came time to sign the new treaty, the Theban ambassadors came forward wishing to sign on behalf of the whole Boeotian League, but the Spartans demanded instead that each Boeotian city sign independently, which the Thebans refused.

With Thebes now isolated, Sparta saw an opportunity to reassert its supremacy in central Greece, and the Spartans immediately sent king Cleombrotus I marching, from his position in Phocis in central Greece, into Boeotia. Rather than take the expected and easier route into Boeotia along the northern side of Mount Helicon, the Spartans instead marched over the hills to the south of Helicon, and then proceeded to Leuctra where they were confronted by a hastily repositioned Boeotian army.

Force sizes and commanders

Several ancient sources give numbers for the sizes of the two armies, but none of these sources gives all the numbers involved, and they nearly all disagree. The general modern consensus is that the Spartan commander King Cleombrotus led approximately 10,000 Peloponnesian infantry, including 700 Spartiates (i.e. full Spartan citizens), and 1,000 cavalry, against 7,000 Boeotian infantry, and 700 cavalry, led by the Theban commander Epaminondas.

According to Xenophon, 700 Spartiates fought at Leuctra, while according to Plutarch, Cleombrotus' Peloponnesian army consisted of 2,000 infantry and 1,000 cavalry, Diodorus Siculus reports that Epaminondas led a force (which included all Thebans of military age) numbering no more than 6,000, to be joined later by a Thessalian force of 1,500 infantry and 500 cavalry. Other, even later sources give much higher numbers for the Peloponnesians, which are harder to believe. According to Polyaenus, the Peloponnesians numbered 40,000 (against only 6,000 "Thebans"), while Frontinus specifies 24,000 infantry and 1,600 cavalry, (against only 3,600 infantry and 400 cavalry). In any case, the similar force ratios (~ 6.5 to 1), given by Polyaenus and Frontinus, are perhaps meant simply to emphasize the difference in the sizes of the two armies.

Order of battle

Bottom: At Leuctra, Epaminondas placed his elite troops on the left facing the Spartans, with the strong left wing advancing more than the weaker right.

The normal practice of the Spartans (and, indeed, the Greeks in general) was to establish their heavily armed infantry in a solid mass, or phalanx, some eight to twelve men deep, with the entire phalanx advancing together. In order to counter the tendency of the phalanx to drift to the right, Greek commanders traditionally placed their most experienced and highly regarded troops on the right wing.

At Leuctra, Cleombrotus' phalanx consisted of two wings, with the Spartans on the right, and his allied troops on the left. Cleombrotus himself occupied the traditional king's position between the first and second morai of the Spartan wing, accompanied by the Spartan hippeis (an elite infantry force numbering 300 men that constituted the royal bodyguard).

Epaminondas also organized his phalanx into two wings, the Thebans comprising one wing, and the rest of the Boeotians the other. However, in a break from tradition, Epaminondas massed his Theban infantry in a very deep column (according to Xenophon, at least fifty shields deep) headed by the elite 300-strong Sacred Band under the command of Pelopidas, placing it on the left, directly opposite Cleombrotus and the Spartan right. The other Boetians were drawn up in a shallower line, progressively further to the right and rear of the proceeding column, in an echelon formation, facing the Spartan allies. Epaminondas's plan was, apparently, to make the outcome depend solely upon an engagement of the Thebans against the Spartans, by sending his Thebans forward, against the Spartans, and refusing (i.e. holding back) his Boeotian allies. Polyaenus reports that, while rallying his Theban troops:

Epaminondas grasped a large snake, showed it to them, and in front of everyone crushed the animal's head. "You see," he said, "that the rest of the body is useless without the head. In just this way, should we crush this Laconian part, the remaining body of the allies would be useless."

The Battle

Accounts of the battle are given by four ancient sources: Xenophon (the only contemporary source), Diodorus Siculus, Plutarch, and Pausanias. The sources are problematic, their accounts are sometimes contradictory, and many particulars of the battle have been the subject of debate among scholars.

Overview

During the battle the massed Theban infantry, with the Sacred Band in front, smashed into the Spartan right wing. They were able to mortally wound the Spartan king Cleombrotus, killing many of the Spartan hippeis, his elite royal bodyguard. The Spartan wing was eventually pushed back, then turned, fled, and was routed. According to Xenophon, the "Lacedaemonians" (i.e the Spartans) themselves lost almost 1,000 dead, including about 400 of the 700 Spartiates present. The Boeotian losses were minimal, "about" 300, according to Diodorus Siculus, while Pausanias reports a total of only 47.

Details

Many more details of the battle (sometimes contradictory) are given by the ancient sources. Xenophon's account, is the only contemporary account, is the most complete, and includes several details not found in any other source. However, rather than being a simple narrative describing what happened, Xenophon's account consists of various reasons (some might say excuses) for the surprising Spartan defeat. Referring to an oracle received by the Thebans saying that the Spartans were destined to be defeated, and other omens portending a Theban victory, Xenophon begins his account of the battle by saying:

Some, to be sure, say that all these things were but devices of the leaders. But in the battle, at any rate, everything turned out adversely for the Lacedaemonians, while for the other side everything went prosperously, even to the gifts of fortune.

According to Xenophon, while both side were still arming themselves, the Spartans' mercenary peltasts (slingers, javelinieers, and/or light-armed skirmishers) attacked the Boeotian camp followers, baggage handlers, and others who did not wish to fight, as they were attempting to withdraw. This caused these men to flee back into the Boeotian army, inadvertently making it stronger. The battle proper then opened with a cavalry engagement, in which the Spartan cavalry was quickly defeated. Xenophon explains this defeat by saying that, as a result of their recent battles against Orchomenus and Thespiae, the Theban cavalry was more experienced, and that, because the Spartan cavalry was made up of men who did not own their horses and arms, and were the least physically able and ambitious, it was of inferior quality. In any case, the Spartan cavalry fled from the field, back through their own infantry, causing a disruption in the Spartan lines. Moreover, this occurred just as the Thebans were charging into them. At this point Xenophon concludes his account of the action by saying that the Spartan line was able to hold long enough for the mortally wounded Cleombrotus to be carried off the field still alive, but eventually "fell back under the pressure of the Theban mass, while those who were on the left wing of the Lacedaemonians, when they saw that the right wing was being pushed back, gave way."

This shows the flank attack that Rüstow and Köchly proposed. Delbrück rejected such an interpretation.

Wilhelm Rüstow and Hermann Köchly, writing in the 19th century, believed that Pelopidas led the Sacred Band out from the column to attack the Spartans in the flank. Hans Delbrück considered this to be a mere misreading of Plutarch. Plutarch does indeed describe Pelopidas leading the Band and catching the Spartans in disorder, but there is nothing in his account that conveys anything other than the Sacred Band being the head of the column. The Spartans being allegedly disordered not because they were taken in the flank but because they were caught in mid-maneuver, extending their line.

Historical significance

Battles in Ancient Greece

The battle is of great significance in Greek history.

The use of these tactics by Epaminondas was, perhaps, a direct result of the use of some similar maneuvers by Pagondas, his countryman, during the Battle of Delium. Further, Philip II of Macedon, who studied and lived in Thebes, was no doubt heavily influenced by the battle to develop his own, highly effective approach to tactics and armament. In turn, his son, Alexander, would go on to develop his father's theories to an entirely new level. Many innovations of Philip and Alexander are traced to this battle. Concentration of force, refused flank, and combined arms were tactics that they used in many of their battles. Philip's victories against the Illyrians and at Chaeronea and Alexander's triumphs at the Granicus, Issus, Gaugamela, and the Hydaspes owe credit to the tactical maneuver used to vanquish the Spartans.

Historians Victor Davis Hanson and Donald Kagan have argued that Epaminondas' oblique formation was not an intentional and preconceived innovation in infantry tactics, but was rather a clever response to circumstances. Because Epaminondas had stacked his left wing to a depth of fifty shields, the rest of his units were naturally left with far fewer troops than normal. This means that their maintenance of a depth of eight to twelve shields had to come at the expense of either number of companies or their width. Because Epaminondas was already outnumbered, he had no choice but to form fewer companies and march them diagonally toward the much longer Spartan line in order to engage as much of it as possible. Hanson and Kagan's argument is therefore that the tactic was more dilatory than anything else. Whatever its motivation, the fact remains that the tactic did represent an innovation and was undoubtedly highly effective.

The battle's political effects were far-reaching: the losses in material strength and prestige (prestige being an inestimably important factor in the Peloponnesian War) sustained by the Spartans at Leuctra and subsequently at the Battle of Mantinea were key in depriving them forever of their supremacy in Greece. Therefore, the battle permanently altered the Greek balance of power, as Sparta was deprived of its former prominence and was reduced to a second-rate power among the Greek city-states.

Theban supremacy in Greece was short-lived, as it was subsequently lost to the Macedonians, led by Philip II.

In popular culture

The battle is fictionalized, though in some detail, in David Gemmell's book, Lion of Macedon, which includes the significant deviation from historical canon in that it is credited to a young Parmenio(n) instead of Epaminondas, who serves merely to gain permission to carry out the echelon tactic.

The battle is the subject of Victor Davis Hanson's 2011 historical fiction novel, The End of Sparta. The battle was featured in an episode of the BBC's Time Commanders. It was featured in the historical fiction graphic novel Serpent and Prey, which takes few creative liberties with the battle's portrayal.

In The Expanse: Persepolis Rising by James S.A. Corey, the final major engagement is referred to as the "Battle of Point Leuctra" in a literary homage to the historical battle. The name was chosen within the novel because the invading force called their solar system Laconia.
