Thermopylae: The Night Raid

The Greek historian Diodorus Siculus, writing in the first century BC, related a story about the Battle of Thermopylae some 400 years earlier that was not recorded in Herodotus. Diodorus and other later historians claim that on the night of the second day of the battle, knowing that his flank had been turned, Leonidas sent a raid into the Persian camp in order to murder the Persian Emperor Xerxes. Most modern historians dismiss this tale as mere legend. Today I want to look more closely at the legend.

The Pass at Thermopylae as it looks today.

In his book on the Battle of Thermopylae, Ernle Bradford* both relates and dismisses the tale of a night raid in the following language: "Diodorus and others also tell a tale, which most authorities have considered suspect, that Leonidas, knowing all was lost, personally led a suicidal attempt on the Persian lines to try to kill Xerxes. We can be sure that this is untrue, for we know that Leonidas stayed to the last at Thermopylae, as was his duty and as befitted a Spartan king." (137)

Tom Holland in his book Persian Fire** is less conclusive commenting in a note that: "Several sources claim that Leonidas, on the eve of the Spartan' last stand, launched a raid on the royal tent and was killed. It is hard to know what is made of this story -- since Leonidas himself certainly died in battle -- unless it hints at a garbled memory of a foiled mission to assassinate Xerxes." (282)

As both historians emphasize, the notion of Leonidas leading a raid into the enemy camp on the eve of the final day of battle is both absurd and demonstrably untrue. First, the C-in-C of an large army composed of diverse allied forces does not take the role of a platoon leader. Leonidas was C-in-C because he commanded the trust and respect of the allied commanders; he could not risk the disintegration of the entire operation by exposing himself to unnecessary risk. Likewise, a Spartan king's place in the line of battle was very rigidly circumscribed by tradition. A Spartan king led from the front protected only by his personal guard, which included Olympic victors. It was considered a great honor in Sparta to be allowed to fight in front of the king. Finally and most importantly, Leonidas died far too publicly on the third day of battle. There were thousands of witnesses to his last hours on the Persian side who lived to tell about it. His corpse was fought over, then mutilated and displayed. Herodotus had the opportunity to speak with the survivors of Thermopylae and his account of Leonidas' death can be trusted in this. There is no way Leonidas led -- and died -- on a raid the night before.

But does that mean the raid itself is impossible? 

In his article "Thermopylae: A glorious sacrifice or failed 'black operation'" Stefanos Skarmintzos notes that Diodorus claims Leonidas had additional Laconian troops with him in addition to the 300 Spartiates of his personal guard. Certainly Spartan fielded 5,000 perioiki hoplites at the Battle of Plataea, and it is thus probably that Leonidas had at least some perioiki troops with him at Thermopylae as well. This may have included the Skiritan, Sparta's light cavalry scouts. Skarmintzos suggests Leonidas may have taken elements of the Krypteia with him as well. 

Assuming there was a Krypteia at this time (and more and more historians question this, arguing it was not created until after the helot revolt of 465), the members of such a unit would have been well-trained and experienced in both night operations and murder. Yet, even if the Krypteia had not yet been created, is it completely unreasonable to imagine some sort of equivalent to the British SAS or U.S. Navy Seals? If not a permanent institution, we should not forget that all Spartan hoplites were trained to move and operate in the dark and the creation of an ad hoc "special task force" to undertake a dangerous and secret mission is hardly unreasonable.

Furthermore, Leonidas had every reason to want to kill the tyrant who had initiated the invasion of the Greek peninsula. Yes, his personal mission was to command the defense at the Pass. That was his place and he knew it was his destiny to die there. However, that is not the same thing as assuming that everyone else was going to die with him or that the sacrifice of his life would be in vain, i.e. in a defeat. 

Leonidas did not go to Thermopylae to die. He went to halt the Persian invasion. His "job" was to do that anyway he could. The assassination of the man driving forward that invasion, of the supreme leader of an absolutist state, offered the prospect of, at a minimum, creating temporary confusion in the enemy camp and, at best, causing the entire invasion to collapse due to fights over the succession. If a spy or a scout suggested to Leonidas that it might be possible to smuggle Spartan (or other Greek) troops into the Persian camp with a chance of gaining access to Xerxes tent and killing him, Leonidas would have been a fool not to attempt such an operation. 

As Skarmintzos puts it: "If the night raid [had been] successful, today we would talk about the great victory at Thermopylae and how a few Greeks resisted the might of an Empire." Yet because it failed, we cannot be sure it ever happened at all. 

Like Stephen Pressfield, I find the notion of a night raid by a select body of Spartan troops tasked with eliminating the man who commanded the might of Persia irresistible as a novelist. A night raid, therefore, features in:

The Road to Thermopylae : Leonidas the Soldier

No, this is not about Thermopylae. This is about Leonidas’ earlier military career. 


First and foremost, Leonidas was one of the few Spartan kings, who was a professional military man. Unlike the Spartan kings before and almost all the Spartan kings after him, Leonidas “enjoyed” the complete program of military training imposed on Spartan citizens from boyhood through ten years of active service, and a lifetime in the reserves thereafter. Thus, Leonidas was one of the only Spartan kings as familiar with every formation and drill employed by the Spartan army as his troops, and as adept with the use of weapons as his fellow citizens. Equally important, having been an ordinary ranker, he knew exactly how they thought, felt and reacted. Leonidas was as much a soldier as he was a commander. This was a significant advantage. It was what made other Spartan commanders like Brasidas and Lysander effective as well.  

Nor was his experience confined to the drill-field.  Sparta in the late archaic was not a city perpetually at war (though readers of Steven Pressfield’s novel Gates of Fire can be forgiven for being misled into believing this). Nevertheless, in Leonidas’ lifetime Lacedaemon was engaged in a number of significant military campaigns. Thus, while Leonidas never fought the more than 20 campaigns Pressfield fantasizes about, he would have gained first- and second-hand experience from a more limited number of wars. 

First, when Leonidas was still a child or youth (depending on his date of birth), Sparta made an unsuccessful attempt to drive the tyrant Polycrates out of Samos.  Notably, this required the deployment of a considerable force by sea and involved a forty-day siege as well as an assault in which some of the Spartans managed to break into the city, but were then cut off and killed. The rest returned.  The failure and the loss of life must have been the topic of many discussions in syssitia across the city for many years of come – probably with recriminations and a lot of “Monday-morning-quarterbacking.” Leonidas, as a young Spartan male serving in the syssitia as part of his upbringing, would undoubtedly have listened avidly to the accounts of this campaign as told by the veterans, who took part.

Roughly ten years later, Leonidas’ half-brother Cleomenes undertook an invasion of Attica, again by sea.  Once again, Sparta’s expeditionary force was defeated and driven back to their ships, this time by Thessalian cavalry.  Leonidas was by this time very likely in his late teens, if not already a young man. Conceivably, he even took part in this expedition, but if so only in a subordinate capacity as an ordinary ranker. Whatever his age and role, Leonidas would have learned a valuable lesson, at least second hand, about the capabilities of cavalry and the advisability of not underestimating it.

Cleomenes undertook no less than three additional campaigns against Athens.  In the first, he successfully dislodged the Athenian tyrant Hippias, but in the second, in which he sought to drive out Cleisthenes and restrict Athenian democracy, he found himself bottled up on the acropolis by the outraged Athenian masses and had to negotiate a truce to withdraw – with his tail between his legs. Given the small and evidently informal nature of these first two campaigns (Herodotus suggests both campaigns were conducted with small volunteer forces), it is unlikely that Leonidas was an active participant in either of these expeditions. 

Burning from the humiliation of his defeat, however, Cleomenes called up the full Spartan army and the allies of the Peloponnesian league.  Spartan law at this time, however, did not allow the full army to deploy outside of Lacedaemon without both kings in command, so Cleomenes was accompanied on this third campaign against Athens by his co-monarch Demaratus.  Demaratus was not as enthusiastic about invading Attica as Cleomenes – and nor were the Peloponnesian allies. Cleomenes’ army got as far as Eleusis, but there the Corinthians drew the line. They had no quarrel with Athens, and they refused to continue. Demaratus sided with the Corinthians. The allied army disintegrated, and the conflict between Cleomenes and Demaratus hog-tied the Spartan army as well. The Spartans had no choice but to return, undefeated but humiliated again.

Leonidas was almost certainly present with the Spartan army during this last campaign against Athens. Depending on his date of birth, he might already have been a junior officer.  Regardless of his military rank, as Cleomenes half-brother and heir apparent, he almost certainly knew what was going on in the command tents, if not directly, then indirectly.  While the campaign would have provided him with no combat experience, it would certainly have taught him a great deal about operations involving multi-national forces -- a lesson that would be very important for his later life.

The next major military campaign of Leonidas’ lifetime was the campaign against Argos that culminated in the dramatic Spartan victory at Sepeia. This campaign again involved the entire active Spartan army, so Leonidas’ participation is almost certain.  Significantly, it also contained a nautical component: the Spartan army was ferried across the Gulf of Argos from Thyrea in Lacedaemon to Nauplia in the Argolid. There followed a massive confrontation with the full Argive army that was at least as numerous if not larger than the all-Spartiate force facing it.  Although the Argives had learned how to read the Spartan signals, Cleomenes cleverly took advantage of this to mislead the Argives into thinking the Spartans were standing down for a meal. As soon as the Argive phalanx broke up, he attacked. The ensuing slaughter allegedly deprived Argos of a generation of fighters, but Cleomenes singularly failed to follow up his battle-field victory with the occupation of the undefended city of Argos. The “lessons learned” for Leonidas would have started with the flexibility of deployment offered by seaborne transport, and included the importance of intelligence (the Argive familiarity with Spartan signals),  and, of course, the advantages of surprise.  

What Leonidas thought of his brother’s slaughter of prisoners and the burning of a sacred wood is unrecorded, but in the absence of evidence to the contrary, we should assume he shared popular Spartan opinion – and this was to put Cleomenes on trial for treason.  The accusation was that Cleomenes had taken a bribe not to take Argos when it lay undefended before a victorious Spartan army -- probably because the prosecution could think of no other plausible explanation for squandering such a splendid opportunity to subdue their traditional enemy after over two hundred years of bitter hostilities.  Herodotus specifically says that Cleomenes was charged by his “enemies” and that he was acquitted because he convinced the ephors that he could not get favorable signs from the gods.

By this time, Lenoidas was probably already married to Gorgo, and he was Cleomenes’ heir.  It is unlikely that he would have been counted among Cleomenes’ enemies.  It is almost equally improbable that he approved of Cleomenes behavior. Cleomenes was acquitted of taking a bribe and he defended himself with weapons (the will of the gods) against which the ephors were helpless; that is not the same thing as saying his actions were applauded even by his supporters.  Furthermore, Leonidas will have taken careful note of the fact that failure to exploit a victory could put a king in jeopardy.

The next significant military engagement of Leonidas’ lifetime was one in which Sparta played no direct role and yet it may have been the most decisive military moment in Leonidas life prior to Thermopylae: the Battle of Marathon. To summarize, Leonidas very probably led the two thousand Spartiates that arrived in Marathon after a dramatic forced march that enabled them to cover the distance from Sparta to Athens in less than three days -- but one day after the decisive battle had been fought. He would have toured the battlefield in company with Athenian commanders and fighters, gleaning a great deal of information about the Persians, their weapons, armor, tactics and morale.  He would also have gained considerable respect for Athenian (and Plataean) fighting capacity.  Leonidas would have seen first-hand at Marathon that Greek hoplites could withstand Persian missiles and Persian cavalry and inflict dramatically higher casualties than they suffered. However, it would also have left a psychological scar: the sense of having come too late.

And so we come to Thermopylae. Leonidas’ determination to deploy when he did, even if he could take only 300 Spartiates with him was, I believe, dictated by his experience at Marathon. Leonidas, who undoubtedly appreciated the military importance of Thermopylae and Artemisium, was determined not to come too late a second time. 

This is not the same thing as believing he was undertaking a suicide mission.  Leonidas had every reason to believe that the force he took north was sufficient to hold the Pass until, with the Karneia and the Olympic Games over, Sparta and other cities could deploy their main forces. Leonidas did not, after all, march north with just 300 men. In addition to the Spartiates, he had perioikoi troops, allies from the Peloponnesian League, Thespians, Thebans and Phocians. Leonidas had between 6,000 and 7,000 Greek hoplites at Thermopylae, a pass that at that time narrowed down to a cart track at two places.

To be sure, Leonidas allegedly knew from the Delphic oracle that his own fate was sealed. He presumably expected to die, but there was no reason to assume his death would be futile. On the contrary, Delphi had promised to save Sparta, if one of her kings fell in battle.  Leonidas most likely believed (or wanted to believe) that although he would die, his army would be victorioius.  Nor did he expect all his accompanying Spartiates to die with him. He took only the fathers of living sons with him was not because he expected them all to die, but because he expected some of them would die but couldn't know which ones. He did not want to risk the extermination of even a single Spartiate family -- not when he had so many men to choose from.

Leonidas’ tactical competence at Thermopylae has been questioned primarily because of his failure to put Spartiates on the mountain trail by which the pass was turned.  The argument is that he failed to take the risk to his flank/rear seriously, and the positioning of Phocian troops on this critical route was amateurish. Hindsight is always clearer than foresight. But even with hindsight, it is not completely convincing that Leonidas should have risked splitting his already very small force to send, say, 100 Spartiates to guard what was essentially a goat-trail.  Furthermore, one thousand men out of a force just six to seven thousand strong represents a very significant commitment of troops available. This suggests that Leonidas took the threat seriously indeed. To imply that a hundred Spartans would have been better than a thousand Phocians reflects modern fascination with the Spartan military myth, but can hardly be considered a serious military assessment. Leonidas’ evident assumption that the locals with the greatest stake in a successful defense of Thermopylae and the best knowledge of the terrain would be the best defenders of the flanking path is more convincing than modern dismissals of such logic. It is tempting to judge a strategy by its result; that is not always fair.

Otherwise, Leonidas appears to have developed a highly effective strategy for defending the Pass, one that effectively neutralized the superiority of numbers on the Persian side and enabled a comparatively small number of defenders to hold the overwhelming might of Xerxes army for two days. Although –- or rather because -- Herodotus does not give us the casualties of the first two days, we can presume that they were not inordinate. The defense of the “Middle Gate” which was wider than the “Eastern” or “Western Gates” appears to have given the Greeks the optimal opportunity to reduce Persian pressure but bring sufficient numbers of their own troops to bear. Equally impressive, Leonidas evidently welded the diverse contingents together and succeeded in getting them to cooperate.  Herodotus says that the allies fought in relays, or turns, so that the troops from each city had time to rest, refresh themselves and tend their wounds between taking their turn at the front. While this sounds logical and reasonable, it is far from self-evident. It would also have required considerable skill in execution -– or each change would have produced confusion that the Persians could have exploited.


Leonidas' military career is described in books II and III of the Leonidas Trilogy.

The Road to Thermopylae - The Reformer King

Most historians confine their commentary on Leonidas to his appearance and departure from the stage of history.  His reign was, after all, quite short (ten years) and there were no known changes to Spartan territory or law, no works of art or monuments, not even any natural disasters that can be dated specifically to the reign of Leonidas.  It is therefore presumptuous of me to label Leonidas a “reformer king.” I know that.


Now that I have your attention….

Looking at Spartan history from the Messenian War to Sparta’s dismal and ignominious end under Rome, the reign of Leonidas represents in many ways a turning point. In crude terms, the archaic age extended from the mid-eight century to the end of the 6th century  BC. The classical age followed. Thus Leonidas’ reign fell at the transition.

In Sparta, it is exactly that transition that represents a particularly sharp and significant break in Sparta’s development.  The history of Sparta as a distinct city-state coincides with the dawn of the archaic period and the Messenian War(s). The latter sparked unrest leading to massive reforms embodied in Sparta’s unique laws. 

Archaic Sparta saw not only the establishment of this new, revolutionary form of government (arguably the first democracy in history), but also a significant flourishing of the arts and trade. Sparta’s most significant monuments (e.g. the Menelaion, the Amyklaion) were constructed in the archaic period. Sparta’s most famous poets – Tyrtaios, Alkman – lived and worked in the archaic age. Spartiate  sculptors produced works for Olympia, while Sparta's pottery was in international demand and exported throughout the 6th century.  Sparta’s archaic bronze works were even more outstanding and competitive, reaching a peak in quality and creativity in the early 6th century.  Not least important, Sparta’s two most admired statesmen in the ancient world, Lycurgus and Chilon, both lived in the archaic period. While many doubt that Lycurgus was a real person and prefer to see him as a mere legend, Chilon was certainly real, and counted as one of the ancient world’s “wise men.”

Sparta in the classical period in contrast is characterized by artistic stagnation and such a dramatic end to Sparta’s competitiveness in trade and manufacturing that those who study only classical and Hellenistic Sparta are completely unaware of Sparta’s impressive earlier accomplishments. Indeed, based on descriptions of the Spartan state and constitution written at the end of the fifth century and later, Sparta appears to have become a city-state that disdained luxury and by inference art itself.  Certainly Sparta’s exports of finished products declined, and a sharp drop in the number of artifacts from this period have been found at the sites of Spartan temples. This may indicate that domestic production was also severely restricted. (Alternatively, younger layers of deposits were lost due to flooding, earthquakes etc.)

Assuming the existing archeological record and the written depictions of Spartan society more-or-less accurately describe classical and later Spartan society, then Sparta underwent a radical, indeed revolutionary, change in the mid-5th century.  The question is why?

There are a number of possible answers: A) the Persian Wars, B) the Great Earthquake of 465 and subsequent population decline, C) a Helot Revolt; D) the bitter war with Athens, and E) All of the Above.

So, what does this have to do with Leonidas?  My thesis is that Leonidas was the last of the archaic kings not just in terms of timing but in terms of policy. Sparta obtained its reputation for opposing tyrants and built up the Peloponnesian League in the second half of the 6th century during the reigns of Leonidas’ two predecessors, his father and half-brother.  These policies reflect on the one hand an interest in world affairs, and on the other a willingness to negotiate and compromise rather than rely on brute force.

The evidence for Leonidas’ cosmopolitanism is first and foremost his election to lead the coalition of Greek states that opposed the Persian invasion of 480. This fact has far too often been interpreted simply as a tribute to Sparta’s position as the leading Greek power of the age.  This ignores the fact that just two years after Leonidas’ death, the same coalition of forces preferred Athenian leadership to submitting to command by Leonidas’ successor Pausanias ― and Pausanias had just led the coalition to a spectacular victory at Plataea! Sparta was not less powerful in 478 than she had been in 480, and her reputation in arms was greater. If simply being Spartan was all that mattered to the allies, then the coalition would have asked Sparta to send King Leotychias or another Spartan general to replace Pausanias, but it did not. Just as Pausasias was not elected in 478, Leonidas was elected in 480, not because he was Spartan but because of who he was.  In 481, Leonidas personally enjoyed the trust of the coalition partners.

Leonidas probably gained that trust through personal contact, and that suggests a degree of travel within the Greek world. He probably attended the pan-Hellenic games regularly, for example. (Other Spartan kings of his age were competitors.) He may also have met leaders from other cities in Sparta itself, if they came to see the Gymopaedia or Hyacinthia, for example.  However, Gorgo allegedly made her famous statement about why Spartan women “rule” their men to a woman from Attica. Since Athenian women weren’t supposed to set foot out of their home let alone outside their city, it is far more likely that the exchange, if it occurred at all, took place in Attica than Lacedaemon. The most logical explanation would be that Gorgo traveled with Leonidas to Athens at some point in his reign. As the Persian threat grew, it would have been very logical to find Leonidas garnering support for a united stand against the invaders by traveling to all major Greek cities, first and foremost Athens, but also Thebes and Corinth.  

During Leonidas’ lifetime, Sparta not only took an active interest in world affairs and exported significant works of art (sculpture, bronze, pottery) overseas, it also commanded respectable naval resources. In the reign of Leonidas’ father, Sparta undertook an expedition against Samos and his half-brother launched a seaborne attack against Attica. The significance of a navy is that it required loyal oarsmen. Rowing a warship is notoriously back-breaking, tedious, stinking work. It was so unpleasant that it was a form of punishment in later centuries and criminals would be condemned to “the galleys.” Slaves, chained to the oar-banks, is an image we carry around with us from films like “Ben Hur.” In fact, however, in the ancient world, particularly in ancient Greece, the crews of warships were predominantly citizens.  This was because no city could afford to entrust the maneuverability and speed of their fighting ships to anyone who did not have a stake in the outcome of an engagement.

The most probable source of competent seamen was the perioikoi residents of Lacedaemon. Perioikoi towns, unlike land-locked Sparta, were often located on the coast (Epidauros Limera, Boiai, Kardamyle, Asine, Pylos, and, of course, Gytheon, to name only a few.) On the other hand, the perioikoi element at Plataea equaled Sparta’s, suggesting that the perioikoi elite did not greatly outnumber the Spartiates themselves. Another source of seamen would have been helots, but if helots were as oppressed and hostile to Sparta as most historians claim, then it would have been suicidal to entrust the oars of naval ships to helot oarsmen.

On the other hand, if conditions for helots were not as consistently severe as generally presumed, then there might have been at least some loyal helots.  Possibly special incentives in the form of emancipation or increased status were offered to helots who served in Sparta’s fledgling navy, or, alternatively, conditions for helots were generally improving throughout the later part of the 6th century when Sparta was evidently enjoying a period of prosperity and comparative peace.  The very fact that the Spartans could take 35,000 helot auxiliaries with them to Plataea suggests widespread support among the helot population. (Suggestions that the Spartans took 35,000 rebellious helots with them when marching out to face the undefeated Persian army are ludicrous.) In short, in 480 BC Sparta had a fleet of at least 16 triremes requiring almost 3,000 oarsmen and 35,000 light troops, all of whom were deemed loyal to the Spartan state. Sparta was putting her future in the hands of these helots.

But roughly one decade later the only recorded helot revolt against Sparta erupted.  This is highly significant because we know that revolutions occur neither when people are content nor when they are most oppressed or exploited.  Uprisings are most likely to occur when a long period of rising living standards and political expectations is abruptly ended by economic or political crisis. My hypothesis is that during Cleomenes’ reign helots had enjoyed a slow but steady increase in living standards, something that accelerated under Leonidas when that economic prosperity was combined with rising political expectations. In the post-Leonidas era, however, these hopes and expectations were abruptly shattered, leading to the explosive situation that culminated in the revolt.

Leonidas was undoubtedly the last of the archaic kings. Sparta’s archaic age saw the foundation and development of Sparta’s political system, flanked by a highly sophisticated foreign policy and the evolution of a powerful alliance system.   Archaic Sparta witnessed the blossoming of artistic and musical accomplishment, the growth of trade in finished products with a wider world, and the growth of naval capability. The archaic was Sparta’s golden age. Would it have continued if Leonidas and his closest companions had not died at Thermopylae? Probably not indefinitely, but possibly the helot revolt that led to intense paranoia in the later 5th century could have been avoided. Likewise, if Leonidas had still lived, neither Pausanias nor Leotychidas would have been given a chance to turn Sparta’s allies into enemies.

The Road to Thermopylae - The Consumate Diplomat: Leonidas of Sparta

Fans of “300” may find it hard to think of Leonidas as a diplomat.  In the Hollywood cartoon, Leonidas is portrayed as the brutal antithesis -- he personally throws a Persian ambassador down a well.  But there is no more historical evidence that Leonidas committed this crime than that Xerxes was a monster. The historical record, foggy and imprecise as it is, suggests that far from being a tactless brute, Leonidas was probably a savvy diplomat. 


Before turning to Leonidas' role as a diplomat, it is useful to remember that Clausewitz claimed that war was diplomacy by other means. This may explain why Sparta, popularly known as a militaristic society, was in fact a city with a long history of effective diplomacy and high regard for the diplomatic profession.

Sparta founded the first non-aggression pact in recorded history when it stopped seeking to conquer its neighbors but sought defensive alliances with them instead. A series of bilateral treaties evolved into what became known as the Peloponnesian League. While initially this organization was an instrument of Spartan hegemony, which required Sparta's allies to follow her lead, in or about 500 BC the allies successfully asserted their power and effectively converted the League into an alliance in which every member - including Sparta - had an equal vote.

Sparta’s diplomatic history, however, started earlier. According to Herodotus, for example, Sparta sent an envoy to the Persian court in mid-6th Century, long before the Persians had become interested in Greece. Allegedly, the Spartan envoy warned the Great King against enslaving Hellenes - which prompted the bewildered master of the Eastern world to ask who (in the hell) the Spartans were?

The Spartans also maintained a temple dedicated to Talthybius, the herald of Agamemnon. It was here that eerie lights and strange noises were allegedly seen and heard after the murder of the Persian ambassadors sent to obtain earth and water in 491. Eventually, the Spartans became so concerned about arousing the wrath of the gods by breaching the diplomatic immunity of the Persian ambassadors they sent two men as sacrifices to Xerxes to atone for the murdered ambassadors. Both men were volunteers and Spartiates of good family, Sperchias and Bulles.

Although usually dismissed as simply “natural,” the fact that Sparta forged an alliance together with Athens, Corinth, Aegina, (all hated rivals of one another!) and other lesser cities to oppose the Persian invasion of 480 is also a brilliant Spartan diplomatic achievement. I say Spartan, because the election of Sparta to lead on land and sea suggested that Athens would not have been able to hold this alliance together without Spartan influence. Arguably, it was Leonidas’ ability to put together a “coalition of the willing” to fight against Xerxes, more than his untimely death at Thermopylae, that was his greatest legacy.

Several of Sparta’s best commanders were also excellent diplomats. Brasidas comes to mind as a man whose greatest power came not from the strength of his arms, but his ability to win over allies and detach cities from the Delian League. Likewise, Sparta’s success in Syracuse was certainly not a military success, no Spartan hoplites were in action at any time. It was, however, an enormous diplomatic success that severely weakened Athenian strength and morale.

The weaker Sparta became, the important it was for Sparta to forge alliances and out-wit rather than out-fight her enemies. It may be an indication of weakness, but it was nevertheless a diplomatic coup that Sparta was one of the first city-states in Greece to forge an alliance with a rising Rome, for example.

All in all, Sparta's diplomatic culture deserves much more attention and research. A comprehensive work on Spartan diplomacy from the Archaic to the Roman Periods would be a welcome addition to existing scholarly literature. For now, however, let me return to the subject of Leonidas.

The evidence for Leonidas’ diplomatic talent is indirect rather than explicit. It is evident in what he did, rather than what is said about him.  Quite simply: During his brief reign, Leonidas managed to forge a coalition of Greek states willing to oppose the Persian invasion and to convince this loose coalition of independent and proud city-states to agree to a unified command.  The significance of such an achievement can be measured by the fact that ten years earlier Athens had been unwilling to place even her own army under the command of a single Athenian; no less than ten generals shared command of the Athenian army at Marathon.  Equally notable, while Leonidas’ brother Cleomenes alienated Lacedaemon’s Peloponnesian allies to the point of provoking revolt, Leonidas won over new Allies such as Mycenae and Tiryns.  

As for the incident with the Persian ambassadors, Herodotus tells us that the Spartans shared the guilt for the murder of the ambassadors.  According to Herodotus, the entire city was threatened by ill-omens and the Spartan Assembly met repeatedly in order to find volunteers from among the citizens willing to appease the Gods by dying in atonement for the murdered Persian ambassadors.  If, as when Cleomenes’ burned the Sacred Wood near Argos, the crime had been committed by either of the Spartan kings, the Spartans would have expected/demanded that the king bear responsibility -- not the citizens. In short, whoever killed the Persian ambassadors, it wasn't Leonidas (or Leotychidas) and so the entire Spartiate population felt collectively guilty about it – something that suggests the Persian emissaries had not been the victims of a spontaneous act of violence but rather condemned by the Spartan Assembly.  (Something which in turn suggests that Spartan Assemblies could be quite rowdy affairs, but that is a subject for another day….)

Leonidas' sophisticated diplomacy is an important theme in the third book of my three-part biographical novel of Leonidas: A Heroic King.
