[7.201] King Xerxes pitched his camp in the region of Malis called Trachinia, while on their side the Greeks occupied the straits. These straits the Greeks in general call Thermopylae (the Hot Gates); but the natives, and those who dwell in the neighbourhood, call them Pylae (the Gates). Here then the two armies took their stand; the one master of all the region lying north of Trachis, the other of the country extending southward of that place to the verge of the continent.
[7.202] The Greeks who at this spot awaited the coming of Xerxes were the following:- From Sparta, three hundred men-at-arms; from Arcadia, a thousand Tegeans and Mantineans, five hundred of each people; a hundred and twenty Orchomenians, from the Arcadian Orchomenus; and a thousand from other cities: from Corinth, four hundred men; from Phlius, two hundred; and from Mycenae eighty. Such was the number from the Peloponnese. There were also present, from Boeotia, seven hundred Thespians and four hundred Thebans.
[7.203] Besides these troops, the Locrians of Opus and the Phocians had obeyed the call of their countrymen, and sent, the former all the force they had, the latter a thousand men. For envoys had gone from the Greeks at Thermopylae among the Locrians and Phocians, to call on them for assistance, and to say - "They were themselves but the vanguard of the host, sent to precede the main body, which might every day be expected to follow them. The sea was in good keeping, watched by the Athenians, the Eginetans, and the rest of the fleet. There was no cause why they should fear; for after all the invader was not a god but a man; and there never had been, and never would be, a man who was not liable to misfortunes from the very day of his birth, and those misfortunes greater in proportion to his own greatness. The assailant therefore, being only a mortal, must needs fall from his glory." Thus urged, the Locrians and the Phocians had come with their troops to Trachis.
[7.204] The various nations had each captains of their own under whom they served; but the one to whom all especially looked up, and who had the command of the entire force, was the Lacedaemonian, Leonidas. Now Leonidas was the son of Anaxandridas, who was the son of Leo, who was the son of Eurycratidas, who was the son of Anaxander, who was the son of Eurycrates, who was the son of Polydorus, who was the son of Alcamenes, who was the son of Telecles, who was the son of Archelaus, who was the son of Agesilaus, who was the son of Doryssus, who was the son of Labotas, who was the son of Echestratus, who was the son of Agis, who was the son of Eurysthenes, who was the son of Aristodemus, who was the son of Aristomachus, who was the son of Cleodaeus, who was the son of Hyllus, who was the son of Hercules.
Leonidas had come to be king of Sparta quite unexpectedly.
[7.205] Having two elder brothers, Cleomenes and Dorieus, he had no thought of ever mounting the throne. However, when Cleomenes died without male offspring, as Dorieus was likewise deceased, having perished in Sicily, the crown fell to Leonidas, who was older than Cleombrotus, the youngest of the sons of Anaxandridas, and, moreover, was married to the daughter of Cleomenes. He had now come to Thermopylae, accompanied by the three hundred men which the law assigned him, whom he had himself chosen from among the citizens, and who were all of them fathers with sons living. On his way he had taken the troops from Thebes, whose number I have already mentioned, and who were under the command of Leontiades the son of Eurymachus. The reason why he made a point of taking troops from Thebes, and Thebes only, was that the Thebans were strongly suspected of being well inclined to the Medes. Leonidas therefore called on them to come with him to the war, wishing to see whether they would comply with his demand, or openly refuse, and disclaim the Greek alliance. They, however, though their wishes leant the other way, nevertheless sent the men.
[7.206] The force with Leonidas was sent forward by the Spartans in advance of their main body, that the sight of them might encourage the allies to fight, and hinder them from going over to the Medes, as it was likely they might have done had they seen that Sparta was backward. They intended presently, when they had celebrated the Carneian festival, which was what now kept them at home, to leave a garrison in Sparta, and hasten in full force to join the army. The rest of the allies also intended to act similarly; for it happened that the Olympic festival fell exactly at this same period. None of them looked to see the contest at Thermopylae decided so speedily; wherefore they were content to send forward a mere advanced guard. Such accordingly were the intentions of the allies.
[7.207] The Greek forces at Thermopylae, when the Persian army drew near to the entrance of the pass, were seized with fear; and a council was held to consider about a retreat. It was the wish of the Peloponnesians generally that the army should fall back upon the Peloponnese, and there guard the Isthmus. But Leonidas, who saw with what indignation the Phocians and Locrians heard of this plan, gave his voice for remaining where they were, while they sent envoys to the several cities to ask for help, since they were too few to make a stand against an army like that of the Medes.
[7.208] While this debate was going on, Xerxes sent a mounted spy to observe the Greeks, and note how many they were, and see what they were doing. He had heard, before he came out of Thessaly, that a few men were assembled at this place, and that at their head were certain Lacedaemonians, under Leonidas, a descendant of Hercules. The horseman rode up to the camp, and looked about him, but did not see the whole army; for such as were on the further side of the wall (which had been rebuilt and was now carefully guarded) it was not possible for him to behold; but he observed those on the outside, who were encamped in front of the rampart. It chanced that at this time the Lacedaemonians held the outer guard, and were seen by the spy, some of them engaged in gymnastic exercises, others combing their long hair. At this the spy greatly marvelled, but he counted their number, and when he had taken accurate note of everything, he rode back quietly; for no one pursued after him, nor paid any heed to his visit. So he returned, and told Xerxes all that he had seen.
[7.209] Upon this, Xerxes, who had no means of surmising the truth - namely, that the Spartans were preparing to do or die manfully - but thought it laughable that they should be engaged in such employments, sent and called to his presence Demaratus the son of Ariston, who still remained with the army. When he appeared, Xerxes told him all that he had heard, and questioned him concerning the news, since he was anxious to understand the meaning of such behaviour on the part of the Spartans. Then Demaratus said -
"I spake to thee, O king! concerning these men long since, when we had but just begun our march upon Greece; thou, however, didst only laugh at my words, when I told thee of all this, which I saw would come to pass. Earnestly do I struggle at all times to speak truth to thee, sire; and now listen to it once more. These men have come to dispute the pass with us; and it is for this that they are now making ready. 'Tis their custom, when they are about to hazard their lives, to adorn their heads with care. Be assured, however, that if thou canst subdue the men who are here and the Lacedaemonians who remain in Sparta, there is no other nation in all the world which will venture to lift a hand in their defence. Thou hast now to deal with the first kingdom and town in Greece, and with the bravest men."
Then Xerxes, to whom what Demaratus said seemed altogether to surpass belief, asked further "how it was possible for so small an army to contend with his?"
"O king!" Demaratus answered, "let me be treated as a liar, if matters fall not out as I say."
[7.210] But Xerxes was not persuaded any the more. Four whole days he suffered to go by, expecting that the Greeks would run away. When, however, he found on the fifth that they were not gone, thinking that their firm stand was mere impudence and recklessness, he grew wroth, and sent against them the Medes and Cissians, with orders to take them alive and bring them into his presence. Then the Medes rushed forward and charged the Greeks, but fell in vast numbers: others however took the places of the slain, and would not be beaten off, though they suffered terrible losses. In this way it became clear to all, and especially to the king, that though he had plenty of combatants, he had but very few warriors. The struggle, however, continued during the whole day.
[7.211] Then the Medes, having met so rough a reception, withdrew from the fight; and their place was taken by the band of Persians under Hydarnes, whom the king called his "Immortals": they, it was thought, would soon finish the business. But when they joined battle with the Greeks, 'twas with no better success than the Median detachment - things went much as before - the two armies fighting in a narrow space, and the barbarians using shorter spears than the Greeks, and having no advantage from their numbers. The Lacedaemonians fought in a way worthy of note, and showed themselves far more skilful in fight than their adversaries, often turning their backs, and making as though they were all flying away, on which the barbarians would rush after them with much noise and shouting, when the Spartans at their approach would wheel round and face their pursuers, in this way destroying vast numbers of the enemy. Some Spartans likewise fell in these encounters, but only a very few. At last the Persians, finding that all their efforts to gain the pass availed nothing, and that, whether they attacked by divisions or in any other way, it was to no purpose, withdrew to their own quarters.
[7.212] During these assaults, it is said that Xerxes, who was watching the battle, thrice leaped from the throne on which he sate, in terror for his army.
Next day the combat was renewed, but with no better success on the part of the barbarians. The Greeks were so few that the barbarians hoped to find them disabled, by reason of their wounds, from offering any further resistance; and so they once more attacked them. But the Greeks were drawn up in detachments according to their cities, and bore the brunt of the battle in turns - all except the Phocians, who had been stationed on the mountain to guard the pathway. So, when the Persians found no difference between that day and the preceding, they again retired to their quarters.
[7.213] Now, as the king was in great strait, and knew not how he should deal with the emergency, Ephialtes, the son of Eurydemus, a man of Malis, came to him and was admitted to a conference. Stirred by the hope of receiving a rich reward at the king's hands, he had come to tell him of the pathway which led across the mountain to Thermopylae; by which disclosure he brought destruction on the band of Greeks who had there withstood the barbarians. This Ephialtes afterwards, from fear of the Lacedaemonians, fled into Thessaly; and during his exile, in an assembly of the Amphictyons held at Pylae, a price was set upon his head by the Pylagorae. When some time had gone by, he returned from exile, and went to Anticyra, where he was slain by Athenades, a native of Trachis. Athenades did not slay him for his treachery, but for another reason, which I shall mention in a later part of my history: yet still the Lacedaemonians honoured him none the less. Thus then did Ephialtes perish a long time afterwards.
[7.214] Besides this there is another story told, which I do not at all believe - to wit, that Onetas the son of Phanagoras, a native of Carystus, and Corydallus, a man of Anticyra, were the persons who spoke on this matter to the king, and took the Persians across the mountain. One may guess which story is true, from the fact that the deputies of the Greeks, the Pylagorae, who must have had the best means of ascertaining the truth, did not offer the reward for the heads of Onetas and Corydallus, but for that of Ephialtes of Trachis; and again from the flight of Ephialtes, which we know to have been on this account. Onetas, I allow, although he was not a Malian, might have been acquainted with the path, if he had lived much in that part of the country; but as Ephialtes was the person who actually led the Persians round the mountain by the pathway, I leave his name on record as that of the man who did the deed.
[7.215] Great was the joy of Xerxes on this occasion; and as he approved highly of the enterprise which Ephialtes undertook to accomplish, he forthwith sent upon the errand Hydarnes, and the Persians under him. The troops left the camp about the time of the lighting of the lamps. The pathway along which they went was first discovered by the Malians of these parts, who soon afterwards led the Thessalians by it to attack the Phocians, at the time when the Phocians fortified the pass with a wall, and so put themselves under covert from danger. And ever since, the path has always been put to an ill use by the Malians.
[7.216] The course which it takes is the following:- Beginning at the Asopus, where that stream flows through the cleft in the hills, it runs along the ridge of the mountain (which is called, like the pathway over it, Anopaea), and ends at the city of Alpenus - the first Locrian town as you come from Malis - by the stone called Melampygus and the seats of the Cercopians. Here it is as narrow as at any other point.
[7.217] The Persians took this path, and, crossing the Asopus, continued their march through the whole of the night, having the mountains of Oeta on their right hand, and on their left those of Trachis. At dawn of day they found themselves close to the summit. Now the hill was guarded, as I have already said, by a thousand Phocian men-at-arms, who were placed there to defend the pathway, and at the same time to secure their own country. They had been given the guard of the mountain path, while the other Greeks defended the pass below, because they had volunteered for the service, and had pledged themselves to Leonidas to maintain the post.
[7.218] The ascent of the Persians became known to the Phocians in the following manner:- During all the time that they were making their way up, the Greeks remained unconscious of it, inasmuch as the whole mountain was covered with groves of oak; but it happened that the air was very still, and the leaves which the Persians stirred with their feet made, as it was likely they would, a loud rustling, whereupon the Phocians jumped up and flew to seize their arms. In a moment the barbarians came in sight, and, perceiving men arming themselves, were greatly amazed; for they had fallen in with an enemy when they expected no opposition. Hydarnes, alarmed at the sight, and fearing lest the Phocians might be Lacedaemonians, inquired of Ephialtes to what nation these troops belonged. Ephialtes told him the exact truth, whereupon he arrayed his Persians for battle. The Phocians, galled by the showers of arrows to which they were exposed, and imagining themselves the special object of the Persian attack, fled hastily to the crest of the mountain, and there made ready to meet death; but while their mistake continued, the Persians, with Ephialtes and Hydarnes, not thinking it worth their while to delay on account of Phocians, passed on and descended the mountain with all possible speed.
[7.219] The Greeks at Thermopylae received the first warning of the destruction which the dawn would bring on them from the seer Megistias, who read their fate in the victims as he was sacrificing. After this deserters came in, and brought the news that the Persians were marching round by the hills: it was still night when these men arrived. Last of all, the scouts came running down from the heights, and brought in the same accounts, when the day was just beginning to break. Then the Greeks held a council to consider what they should do, and here opinions were divided: some were strong against quitting their post, while others contended to the contrary. So when the council had broken up, part of the troops departed and went their ways homeward to their several states; part however resolved to remain, and to stand by Leonidas to the last.
[7.220] It is said that Leonidas himself sent away the troops who departed, because he tendered their safety, but thought it unseemly that either he or his Spartans should quit the post which they had been especially sent to guard. For my own part, I incline to think that Leonidas gave the order, because he perceived the allies to be out of heart and unwilling to encounter the danger to which his own mind was made up. He therefore commanded them to retreat, but said that he himself could not draw back with honour; knowing that, if he stayed, glory awaited him, and that Sparta in that case would not lose her prosperity. For when the Spartans, at the very beginning of the war, sent to consult the oracle concerning it, the answer which they received from the Pythoness was "that either Sparta must be overthrown by the barbarians, or one of her kings must perish." The prophecy was delivered in hexameter verse, and ran thus:-
O ye men who dwell in the streets of broad Lacedaemon!
Either your glorious town shall be sacked by the children of Perseus,
Or, in exchange, must all through the whole Laconian country
Mourn for the loss of a king, descendant of great Heracles.
He cannot be withstood by the courage of bulls nor of lions,
Strive as they may; he is mighty as Jove; there is nought that shall stay him,
Till he have got for his prey your king, or your glorious city.
