Μάχη ΘερμοπυλώνThe original information for the Battle of Thermopylae comes from Herodotus (his book : Polymnia) and from Diodorus from Sicily (Diodorus Siculus).
In 1837, British General Gordon visited the area, researched and revealed the battle, wrote a book  and this has been the basis of contemporary publications on the subject.    Today there are many writers inspired by the Battle.
After the description of the Battle (at he bottom of this page), you can see the original ancient text of Herodotus.

The Battle of Thermopylae

Greek: Μάχη τῶν Θερμοπυλῶν, ( Machē tōn Thermopylōn) was fought between an alliance ofGreek city-states, led by King Leonidas of Sparta, and the Persian Empire of Xerxes I over the course of three days, during the second Persian invasion of Greece. It took place simultaneously with the naval battle at Artemisium, in August or September 480 BC, at the narrow coastal pass ofThermopylae (‘The Hot Gates’).

The Persian invasion was a delayed response to the defeat of the first Persian invasion of Greece, which had been ended by the Athenian victory at the Battle of Marathon in 490 BC. Xerxes had amassed a huge army and navy, and set out to conquer all of Greece. The Athenian generalThemistocles had proposed that the allied Greeks block the advance of the Persian army at the pass of Thermopylae, and simultaneously block the Persian navy at the Straits of Artemisium.

A Greek force of approximately 7,000 men marched north to block the pass in the summer of 480 BC. The Persian army, alleged by the ancient sources to have numbered over one million but today considered to have been much smaller (various figures are given by scholars ranging between about 100,000 and 300,000),[7][8] arrived at the pass in late August or early September. Vastly outnumbered, the Greeks held off the Persians for seven days in total (including three of battle), before the rear-guard was annihilated in one of history’s most famous last stands.

During two full days of battle, the small force led by King Leonidas I of Sparta blocked the only road by which the massive Persian army could pass. After the second day of battle, a local resident named Ephialtes betrayed the Greeks by revealing a small path that led behind the Greek lines. Aware that his force was being outflanked, Leonidas dismissed the bulk of the Greek army, and remained to guard the rear with 300 Spartans, 700 Thespians, 400 Thebans and perhaps a few hundred others, the vast majority of whom were killed.

After this engagement, the Greek navy, under the command of the Athenian politician Themistocles, at Artemisium received news of the defeat at Thermopylae. Since the Greek’s strategy required both Thermopylae and Artemisium to be held, and given their losses, the withdrawal to Salamis was decided. The Persians overran Boeotia and then captured the evacuated Athens. However, seeking a decisive victory over the Persian fleet, the Greek fleet attacked and defeated the invaders at the Battle of Salamis in late 480 BC. Fearing to be trapped in Europe, Xerxes withdrew with much of his army to Asia (losing most to starvation and disease), leaving Mardonius to complete the conquest of Greece. The following year, however, saw a Greek army decisively defeat the Persians at the Battle of Plataea, thereby ending the Persian invasion.

Both ancient and modern writers have used the Battle of Thermopylae as an example of the power of a patriotic army defending native soil. The performance of the defenders at the battle of Thermopylae is also used as an example of the advantages of training, equipment, and good use of terrain as force multipliers and has become a symbol of courage against overwhelming odds.

FULL TEXT   from   HERODOTUS,   book  VII,   POLYMNIA

[7.175] The Greeks, on their return to the Isthmus, took counsel together concerning the words of Alexander, and considered where they should fix the war, and what places they should occupy. The opinion which prevailed was that they should guard the pass of Thermopylae; since it was narrower than the Thessalian defile, and at the same time nearer to them. Of the pathway, by which the Greeks who fell at Thermopylae were intercepted, they had no knowledge, until, on their arrival at Thermopylae, it was discovered to them by the Trachinians. This pass then it was determined that they should guard, in order to prevent the barbarians from penetrating into Greece through it; and at the same time it was resolved that the fleet should proceed to Artemisium, in the region of Histiaeotis, for, as those places are near to one another, it would be easy for the fleet and army to hold communication. The two places may be thus described.

[7.176] Artemisium is where the sea of Thrace contracts into a narrow channel, running between the isle of Sciathus and the mainland of Magnesia. When this narrow strait is passed you come to the line of coast called Artemisium; which is a portion of Euboea, and contains a temple of Artemis (Diana). As for the entrance into Greece by Trachis, it is, at its narrowest point, about fifty feet wide. This however is not the place where the passage is most contracted; for it is still narrower a little above and a little below Thermopylae. At Alpini, which is lower down than that place, it is only wide enough for a single carriage; and up above, at the river Phoenix, near the town called Anthela, it is the same. West of Thermopylae rises a lofty and precipitous hill, impossible to climb, which runs up into the chain of Oeta; while to the east the road is shut in by the sea and by marshes. In this place are the warm springs, which the natives call «The Cauldrons»; and above them stands an altar sacred to Hercules. A wall had once been carried across the opening; and in this there had of old times been a gateway. These works were made by the Phocians, through fear of the Thessalians, at the time when the latter came from Thesprotia to establish themselves in the land of Aeolis, which they still occupy. As the Thessalians strove to reduce Phocis, the Phocians raised the wall to protect themselves, and likewise turned the hot springs upon the pass, that so the ground might be broken up by watercourses, using thus all possible means to hinder the Thessalians from invading their country. The old wall had been built in very remote times; and the greater part of it had gone to decay through age. Now however the Greeks resolved to repair its breaches, and here make their stand against the barbarian. At this point there is a village very nigh the road, Alpeni by name, from which the Greeks reckoned on getting corn for their troops.

[7.177] These places, therefore, seemed to the Greeks fit for their purpose. Weighing well all that was likely to happen, and considering that in this region the barbarians could make no use of their vast numbers, nor of their cavalry, they resolved to await here the invader of Greece. And when news reached them of the Persians being in Pieria, straightway they broke up from the Isthmus, and proceeded, some on foot to Thermopylae, others by sea to Artemisium.

[7.178] The Greeks now made all speed to reach the two stations; and about the same time – the Delphians, alarmed both for themselves and for their country, consulted the god, and received for answer a command to «pray to the winds, for the winds would do Greece good service.» So when this answer was given them, forthwith the Delphians sent word of the prophecy to those Greeks who were zealous for freedom, and, cheering them thereby amid the fears which they entertained with respect to the barbarian, earned their everlasting gratitude. This done, they raised an altar to the winds at Thyia (where Thyia, the daughter of Cephissus, from whom the region takes its name, has a precinct), and worshipped them with sacrifices. And even to the present day the Delphians sacrifice to the winds, because of this oracle.

[7.179] The fleet of Xerxes now departed from Therma; and ten of the swiftest sailing ships ventured to stretch across direct for Sciathus, at which place there were upon the look-out three vessels belonging to the Greeks, one a ship of Troezen, another of Egina, and the third from Athens. These vessels no sooner saw from a distance the barbarians approaching than they all hurriedly took to flight.

[7.180] The barbarians at once pursued, and the Troezenian ship, which was commanded by Prexinus, fell into their hands. Hereupon the Persians took the handsomest of the men-at-arms, and drew him to the prow of the vessel, where they sacrificed him; for they thought the man a good omen to their cause, seeing that he was at once so beautiful, and likewise the first captive they had made. The man who was slain in this way was called Leo; and it may be that the name he bore helped him to his fate in some measure.

[7.181] The Eginetan trireme, under its captain, Asonides, gave the Persians no little trouble, one of the men-at-arms, Pythes, the son of Ischenous, distinguishing himself beyond all the others who fought that day. After the ship was taken this man continued to resist, and did not cease fighting till he fell quite covered with wounds. The Persians who served as men-at-arms in the squadron, finding that he was not dead, but still breathed, and being very anxious to save his life, since he had behaved so valiantly, dressed his wounds with myrrh, and bound them up with bandages of cotton. Then, when they were returned to their own station, they displayed their prisoner admiringly to the whole host, and behaved towards him with much kindness; but all the rest of the ship’s crew were treated merely as slaves.

[7.182] Thus did the Persians succeed in taking two of the vessels. The third, a trireme commanded by Phormus of Athens, took to flight and ran aground at the mouth of the river Peneus. The barbarians got possession of the bark but not of the men. For the Athenians had no sooner run their vessel aground than they leapt out, and made their way through Thessaly back to Athens.

When the Greeks stationed at Artemisium learnt what had happened by fire-signals from Sciathus, so terrified were they, that, quitting their anchorage-ground at Artemisium, and leaving scouts to watch the foe on the highlands of Euboea, they removed to Chalcis, intending to guard the Euripus.

[7.183] Meantime three of the ten vessels sent forward by the barbarians advanced as far as the sunken rock between Sciathus and Magnesia, which is called «The Ant,» and there set up a stone pillar which they had brought with them for that purpose. After this, their course being now clear, the barbarians set sail with all their ships from Therma, eleven days from the time that the king quitted the town. The rock, which lay directly in their course, had been made known to them by Pammon of Scyros. A day’s voyage without a stop brought them to Sepias in Magnesia, and to the strip of coast which lies between the town of Casthanaea and the promontory of Sepias.

[7.184] As far as this point then, and on land, as far as Thermopylae, the armament of Xerxes had been free from mischance; and the numbers were still, according to my reckoning, of the following amount. First there was the ancient complement of the twelve hundred and seven vessels which came with the king from Asia – the contingents of the nations severally – amounting, if we allow to each ship a crew of two hundred men, to 241,400 – Each of these vessels had on board, besides native soldiers, thirty fighting men, who were either Persians, Medes, or Sacans; which gives an addition of 36,210. To these two numbers I shall further add the crews of the penteconters; which may be reckoned, one with another, at fourscore men each. Of such vessels there were (as I said before) three thousand; and the men on board them accordingly would be 240,000. This was the sea force brought by the king from Asia; and it amounted in all to 517,610 men. The number of the foot soldiers was 1,700,000; that of the horsemen 80,000; to which must be added the Arabs who rode on camels, and the Libyans who fought in chariots, whom I reckon at 20,000. The whole number, therefore, of the land and sea forces added together amounts to 2,317,610 men. Such was the force brought from Asia, without including the camp followers, or taking any account of the provision- ships and the men whom they had on board.

[7.185] To the amount thus reached we have still to add the forces gathered in Europe, concerning which I can only speak from conjecture. The Greeks dwelling in Thrace, and in the islands off the coast of Thrace, furnished to the fleet one hundred and twenty ships; the crews of which would amount to 24,000 men. Besides these, footmen were furnished by the Thracians, the Paeonians, the Eordians, the Bottiaeans, by the Chalcidean tribes, by the Brygians, the Pierians, the Macedonians, the Perrhaebians the Enianians, the Dolopians, the Magnesians, the Achaeans and by all the dwellers upon the Thracian sea-board; and the forces of these nations amounted, I believe, to three hundred thousand men. These numbers, added to those of the force which came out of Asia, make the sum of the fighting men 2,641,610.

[7.186] Such then being the number of the fighting men, it is my belief that the attendants who followed the camp, together with the crews of the corn-barks, and of the other craft accompanying the army, made up an amount rather above than below that of the fighting men. However I will not reckon them as either fewer or more, but take them at an equal number. We have therefore to add to the sum already reached an exactly equal amount. This will give 5,283,220 as the whole number of men brought by Xerxes, the son of Darius, as far as Sepias and Thermopylae.

[7.187] Such then was the amount of the entire host of Xerxes. As for the number of the women who ground the corn, of the concubines, and the eunuchs, no one can give any sure account of it; nor can the baggage-horses and other sumpter-beasts, nor the Indian hounds which followed the army, be calculated, by reason of their multitude. Hence I am not at all surprised that the water of the rivers was found too scant for the army in some instances; rather it is a marvel to me how the provisions did not fail, when the numbers were so great. For I find on calculation that if each man consumed no more than a choenix of corn a day, there must have been used daily by the army 110,340 medimni, and this without counting what was eaten by the women, the eunuchs, the sumpter-beasts, and the hounds. Among all this multitude of men there was not one who, for beauty and stature, deserved more than Xerxes himself to wield so vast a power.

[7.188] The fleet then, as I said, on leaving Therma, sailed to the Magnesian territory, and there occupied the strip of coast between the city of Casthanaea and Cape Sepias. The ships of the first row were moored to the land, while the remainder swung at anchor further off. The beach extended but a very little way, so that they had to anchor off the shore, row upon row, eight deep. In this manner they passed the night. But at dawn of day calm and stillness gave place to a raging sea, and a violent storm, which fell upon them with a strong gale from the east – a wind which the people in those parts call Hellespontias. Such of them as perceived the wind rising, and were so moored as to allow of it, forestalled the tempest by dragging their ships up on the beach, and in this way saved both themselves and their vessels. But the ships which the storm caught out at sea were driven ashore, some of them near the place called Ipni, or «The Ovens,» at the foot of Pelion; others on the strand itself; others again about Cape Sepias; while a portion were dashed to pieces near the cities of Meliboea and Casthanaea. There was no resisting the tempest.

[7.189] It is said that the Athenians had called upon Boreas to aid the Greeks, on account of a fresh oracle which had reached them, commanding them to «seek help from their son-in-law.» For Boreas, according to the tradition of the Greeks, took to wife a woman of Attica, viz., Orithyia, the daughter of Erechtheus. So the Athenians, as the tale goes, considering that this marriage made Boreas their son-in-law, and perceiving, while they lay with their ships at Chalcis of Euboea, that the wind was rising, or, it may be, even before it freshened, offered sacrifice both to Boreas and likewise to Orithyia, entreating them to come to their aid and to destroy the ships of the barbarians, as they did once before off Mount Athos. Whether it was owing to this that Boreas fell with violence on the barbarians at their anchorage I cannot say; but the Athenians declare that they had received aid from Boreas before, and that it was he who now caused all these disasters. They therefore, on their return home, built a temple to this god on the banks of the Ilissus.

[7.190] Such as put the loss of the Persian fleet in this storm at the lowest say that four hundred of their ships were destroyed, that a countless multitude of men were slain, and a vast treasure engulfed. Ameinocles, the son of Cretines, a Magnesian, who farmed land near Cape Sepias, found the wreck of these vessels a source of great gain to him; many were the gold and silver drinking-cups, cast up long afterwards by the surf, which he gathered; while treasure-boxes too which had belonged to the Persians, and golden articles of all kinds and beyond count, came into his possession. Ameinocles grew to be a man of great wealth in this way; but in other respects things did not go over well with him: he too, like other men, had his own grief – the calamity of losing his offspring.

[7.191] As for the number of the provision craft and other merchant ships which perished, it was beyond count. Indeed, such was the loss, that the commanders of the sea force, fearing lest in their shattered condition the Thessalians should venture on an attack, raised a lofty barricade around their station out of the wreck of the vessels cast ashore. The storm lasted three days. At length the Magians, by offering victims to the Winds, and charming them with the help of conjurers, while at the same time they sacrificed to Thetis and the Nereids, succeeded in laying the storm four days after it first began; or perhaps it ceased of itself. The reason of their offering sacrifice to Thetis was this: they were told by the Ionians that here was the place whence Peleus carried her off, and that the whole promontory was sacred to her and to her sister Nereids. So the storm lulled upon the fourth day.

[7.192] The scouts left by the Greeks about the highlands of Euboea hastened down from their stations on the day following that whereon the storm began, and acquainted their countrymen with all that had befallen the Persian fleet. These no sooner heard what had happened than straightway they returned thanks to Neptune the Saviour, and poured libations in his honour; after which they hastened back with all speed to Artemisium, expecting to find a very few ships left to oppose them, and arriving there for the second time, took up their station on that strip of coast: nor from that day to the present have they ceased to address Neptune by the name then given him, of «Saviour.»

[7.193] The barbarians, when the wind lulled and the sea grew smooth, drew their ships down to the water, and proceeded to coast along the mainland. Having then rounded the extreme point of Magnesia, they sailed straight into the bay that runs up to Pagasae. There is a place in this bay, belonging to Magnesia, where Hercules is said to have been put ashore to fetch water by Jason and his companions; who then deserted him and went on their way to Aea in Colchis, on board the ship Argo, in quest of the golden fleece. From the circumstance that they intended, after watering their vessel at this place, to quit the shore and launch forth into the deep, it received the name of Aphetae. Here then it was that the fleet of Xerxes came to an anchor.

[7.194] Fifteen ships, which had lagged greatly behind the rest, happening to catch sight of the Greek fleet at Artemisium, mistook it for their own, and sailing down into the midst of it, fell into the hands of the enemy. The commander of this squadron was Sandoces, the son of Thamasius, governor of Cyme, in Aeolis. He was of the number of the royal judges, and had been crucified by Darius some time before, on the charge of taking a bribe to determine a cause wrongly; but while he yet hung on the cross, Darius bethought him that the good deeds of Sandoces towards the king’s house were more numerous than his evil deeds; and so, confessing that he had acted with more haste than wisdom, he ordered him to be taken down and set at large. Thus Sandoces escaped destruction at the hands of Darius, and was alive at this time; but he was not fated to come off so cheaply from his second peril; for as soon as the Greeks saw the ships making towards them, they guessed their mistake, and putting to sea, took them without difficulty.

[7.195] Aridolis, tyrant of Alabanda in Caria, was on board one of the ships, and was made prisoner; as also was the Paphian general, Penthylus, the son of Domonous, who was on board another. This person had brought with him twelve ships from Paphos, and, after losing eleven in the storm off Sepias, was taken in the remaining one as he sailed towards Artemisium. The Greeks, after questioning their prisoners as much as they wished concerning the forces of Xerxes, sent them away in chains to the Isthmus of Corinth.

[7.196] The sea force of the barbarians, with the exception of the fifteen ships commanded (as I said) by Sandoces, came safe to Aphetae. Xerxes meanwhile, with the land army, had proceeded through Thessaly and Achaea, and three days earlier, had entered the territory of the Malians. In Thessaly, he matched his own horses against the Thessalian, which he heard were the best in Greece, but the Greek coursers were left far behind in the race. All the rivers in this region had water enough to supply his army, except only the Onochonus; but in Achaea, the largest of the streams, the Apidanus, barely held out.

[7.197] On his arrival at Alus in Achaea, his guides, wishing to inform him of everything, told him the tale known to the dwellers in those parts concerning the temple of the Laphystian Jupiter – how that Athamas the son of Aeolus took counsel with Ino and plotted the death of Phrixus; and how that afterwards the Achaeans, warned by an oracle, laid a forfeit upon his posterity, forbidding the eldest of the race ever to enter into the court-house (which they call the people’s house), and keeping watch themselves to see the law obeyed. If one comes within the doors, he can never go out again except to be sacrificed. Further, they told him how that many persons, when on the point of being slain, are seized with such fear that they flee away and take refuge in some other country; and that these, if they come back long afterwards, and are found to be the persons who entered the court-house, are led forth covered with chaplets, and in a grand procession, and are sacrificed. This forfeit is paid by the descendants of Cytissorus the son of Phrixus, because, when the Achaeans, in obedience to an oracle, made Athamas the son of Aeolus their sin-offering, and were about to slay him, Cytissorus came from Aea in Colchis and rescued Athamus; by which deed he brought the anger of the god upon his own posterity. Xerxes, therefore, having heard this story, when he reached the grove of the god, avoided it, and commanded his army to do the like. He also paid the same respect to the house and precinct of the descendants of Athamas.

[7.198] Such were the doing of Xerxes in Thessaly and in Achaea, From hence he passed on into Malis, along the shores of a bay, in which there is an ebb and flow of the tide daily. By the side of this bay lies a piece of flat land, in one part broad, but in another very narrow indeed, around which runs a range of lofty hills, impossible to climb, enclosing all Malis within them, and called the Trachinian cliffs. The first city upon the bay, as you come from Achaea, is Anticyra, near which the river Spercheius, flowing down from the country of the Enianians, empties itself into the sea. About twenty furlongs from this stream there is a second river, called the Dyras, which is said to have appeared first to help Hercules when he was burning. Again, at the distance of twenty furlongs, there is a stream called the Melas, near which, within about five furlongs, stands the city of Trachis.

[7.199] At the point where this city is built, the plain between the hills and the sea is broader than at any other, for it there measures 22,000 plethra. South of Trachis there is a cleft in the mountain-range which shuts in the territory of Trachinia; and the river Asopus issuing from this cleft flows for a while along the foot of the hills.

[7.200] Further to the south, another river, called the Phoenix, which has no great body of water, flows from the same hills, and falls into the Asopus. Here is the narrowest place of all; for in this part there is only a causeway wide enough for a single carriage. From the river Phoenix to Thermopylae is a distance of fifteen furlongs; and in this space is situate the village called Anthela, which the river Asopus passes ere it reaches the sea. The space about Anthela is of some width, and contains a temple of Amphictyonian Ceres, as well as the seats of the Amphictyonic deputies, and a temple of Amphictyon himself.

[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.

The remembrance of this answer, I think, and the wish to secure the whole glory for the Spartans, caused Leonidas to send the allies away. This is more likely than that they quarrelled with him, and took their departure in such unruly fashion.

[7.221] To me it seems no small argument in favour of this view, that the seer also who accompanied the army, Megistias, the Acarnanian – said to have been of the blood of Melampus, and the same who was led by the appearance of the victims to warn the Greeks of the danger which threatened them – received orders to retire (as it is certain he did) from Leonidas, that he might escape the coming destruction. Megistias, however, though bidden to depart, refused, and stayed with the army; but he had an only son present with the expedition, whom he now sent away.

[7.222] So the allies, when Leonidas ordered them to retire, obeyed him and forthwith departed. Only the Thespians and the Thebans remained with the Spartans; and of these the Thebans were kept back by Leonidas as hostages, very much against their will. The Thespians, on the contrary, stayed entirely of their own accord, refusing to retreat, and declaring that they would not forsake Leonidas and his followers. So they abode with the Spartans, and died with them. Their leader was Demophilus, the son of Diadromes.

[7.223] At sunrise Xerxes made libations, after which he waited until the time when the forum is wont to fill, and then began his advance. Ephialtes had instructed him thus, as the descent of the mountain is much quicker, and the distance much shorter, than the way round the hills, and the ascent. So the barbarians under Xerxes began to draw nigh; and the Greeks under Leonidas, as they now went forth determined to die, advanced much further than on previous days, until they reached the more open portion of the pass. Hitherto they had held their station within the wall, and from this had gone forth to fight at the point where the pass was the narrowest. Now they joined battle beyond the defile, and carried slaughter among the barbarians, who fell in heaps. Behind them the captains of the squadrons, armed with whips, urged their men forward with continual blows. Many were thrust into the sea, and there perished; a still greater number were trampled to death by their own soldiers; no one heeded the dying. For the Greeks, reckless of their own safety and desperate, since they knew that, as the mountain had been crossed, their destruction was nigh at hand, exerted themselves with the most furious valour against the barbarians.

[7.224] By this time the spears of the greater number were all shivered, and with their swords they hewed down the ranks of the Persians; and here, as they strove, Leonidas fell fighting bravely, together with many other famous Spartans, whose names I have taken care to learn on account of their great worthiness, as indeed I have those of all the three hundred. There fell too at the same time very many famous Persians: among them, two sons of Darius, Abrocomes and Hyperanthes, his children by Phratagune, the daughter of Artanes. Artanes was brother of King Darius, being a son of Hystaspes, the son of Arsames; and when he gave his daughter to the king, he made him heir likewise of all his substance; for she was his only child.

[7.225] Thus two brothers of Xerxes here fought and fell. And now there arose a fierce struggle between the Persians and the Lacedaemonians over the body of Leonidas, in which the Greeks four times drove back the enemy, and at last by their great bravery succeeded in bearing off the body. This combat was scarcely ended when the Persians with Ephialtes approached; and the Greeks, informed that they drew nigh, made a change in the manner of their fighting. Drawing back into the narrowest part of the pass, and retreating even behind the cross wall, they posted themselves upon a hillock, where they stood all drawn up together in one close body, except only the Thebans. The hillock whereof I speak is at the entrance of the straits, where the stone lion stands which was set up in honour of Leonidas. Here they defended themselves to the last, such as still had swords using them, and the others resisting with their hands and teeth; till the barbarians, who in part had pulled down the wall and attacked them in front, in part had gone round and now encircled them upon every side, overwhelmed and buried the remnant which was left beneath showers of missile weapons.

[7.226] Thus nobly did the whole body of Lacedaemonians and Thespians behave; but nevertheless one man is said to have distinguished himself above all the rest, to wit, Dieneces the Spartan. A speech which he made before the Greeks engaged the Medes, remains on record. One of the Trachinians told him, «Such was the number of the barbarians, that when they shot forth their arrows the sun would be darkened by their multitude.» Dieneces, not at all frightened at these words, but making light of the Median numbers, answered «Our Trachinian friend brings us excellent tidings. If the Medes darken the sun, we shall have our fight in the shade.» Other sayings too of a like nature are reported to have been left on record by this same person.

[7.227] Next to him two brothers, Lacedaemonians, are reputed to have made themselves conspicuous: they were named Alpheus and Maro, and were the sons of Orsiphantus. There was also a Thespian who gained greater glory than any of his countrymen: he was a man called Dithyrambus, the son of Harmatidas.

[7.228] The slain were buried where they fell; and in their honour, nor less in honour of those who died before Leonidas sent the allies away, an inscription was set up, which said:-

Here did four thousand men from Pelops’ land
Against three hundred myriads bravely stand.

This was in honour of all. Another was for the Spartans alone:-

Go, stranger, and to Lacedaemon tell
That here, obeying her behests, we fell.

This was for the Lacedaemonians. The seer had the following:-

The great Megistias’ tomb you here may view,
Whom slew the Medes, fresh from Spercheius’ fords.
Well the wise seer the coming death foreknew,
Yet scorned he to forsake his Spartan lords.

These inscriptions, and the pillars likewise, were all set up by the Amphictyons, except that in honour of Megistias, which was inscribed to him (on account of their sworn friendship) by Simonides, the son of Leoprepes.

[7.229] Two of the three hundred, it is said, Aristodemus and Eurytus, having been attacked by a disease of the eyes, had received orders from Leonidas to quit the camp; and both lay at Alpeni in the worst stage of the malady. These two men might, had they been so minded, have agreed together to return alive to Sparta; or if they did not like to return, they might have gone both to the field and fallen with their countrymen. But at this time, when either way was open to them, unhappily they could not agree, but took contrary courses. Eurytus no sooner heard that the Persians had come round the mountain than straightway he called for his armour, and having buckled it on, bade his helot lead him to the place where his friends were fighting. The helot did so, and then turned and fled; but Eurytus plunged into the thick of the battle, and so perished. Aristodemus, on the other hand, was faint of heart, and remained at Alpeni. It is my belief that if Aristodemus only had been sick and returned, or if both had come back together, the Spartans would have been content and felt no anger; but when there were two men with the very same excuse, and one of them was chary of his life, while the other freely gave it, they could not but be very wroth with the former.

[7.230] This is the account which some give of the escape of Aristodemus. Others say that he, with another, had been sent on a message from the army, and, having it in his power to return in time for the battle, purposely loitered on the road, and so survived his comrades; while his fellow-messenger came back in time, and fell in the battle.

[7.231] When Aristodemus returned to Lacedaemon, reproach and disgrace awaited him; disgrace, inasmuch as no Spartan would give him a light to kindle his fire, or so much as address a word to him; and reproach, since all spoke of him as «the craven.» However he wiped away all his shame afterwards at the battle of Plataea.

[7.232] Another of the three hundred is likewise said to have survived the battle, a man named Pantites, whom Leonidas had sent on an embassy into Thessaly. He, they say, on his return to Sparta, found himself in such disesteem that he hanged himself.

[7.233] The Thebans under the command of Leontiades remained with the Greeks, and fought against the barbarians, only so long as necessity compelled them. No sooner did they see victory inclining to the Persians, and the Greeks under Leonidas hurrying with all speed towards the hillock, than they moved away from their companions, and with hands upraised advanced towards the barbarians, exclaiming, as was indeed most true – «that they for their part wished well to the Medes, and had been among the first to give earth and water to the king; force alone had brought them to Thermopylae; and so they must not be blamed for the slaughter which had befallen the king’s army.» These words, the truth of which was attested by the Thessalians, sufficed to obtain the Thebans the grant of their lives. However, their good fortune was not without some drawback; for several of them were slain by the barbarians on their first approach; and the rest, who were the greater number, had the royal mark branded upon their bodies by the command of Xerxes – Leontiades, their captain, being the first to suffer. (This man’s son, Eurymachus, was afterwards slain by the Plataeans, when he came with a band of 400 Thebans, and seized their city.)

[7.234] Thus fought the Greeks at Thermopylae. And Xerxes, after the fight was over, called for Demaratus to question him; and began as follows:-

«Demaratus, thou art a worthy man; thy true-speaking proves it. All has happened as thou didst forewarn. Now then, tell me, how many Lacedaemonians are there left, and of those left how many are such brave warriors as these? Or are they all alike?»

«O king!» replied the other, «the whole number of the Lacedaemonians is very great; and many are the cities which they inhabit. But I will tell thee what thou really wishest to learn. There is a town of Lacedaemon called Sparta, which contains within it about eight thousand full-grown men. They are, one and all, equal to those who have fought here. The other Lacedaemonians are brave men, but not such warriors as these.»

«Tell me now, Demaratus,» rejoined Xerxes, «how we may with least trouble subdue these men. Thou must know all the paths of their counsels, as thou wert once their king.»

[7.235] Then Demaratus answered – «O king! since thou askest my advice so earnestly, it is fitting that I should inform thee what I consider to be the best course. Detach three hundred vessels from the body of thy fleet, and send them to attack the shores of Laconia. There is an island called Cythera in those parts, not far from the coast, concerning which Chilon, one of our wisest men, made the remark that Sparta would gain if it were sunk to the bottom of the sea – so constantly did he expect that it would give occasion to some project like that which I now recommend to thee. I mean not to say that he had a foreknowledge of thy attack upon Greece; but in truth he feared all armaments. Send thy ships then to this island, and thence affright the Spartans. If once they have a war of their own close to their doors, fear not their giving any help to the rest of the Greeks while thy land force is engaged in conquering them. In this way may all Greece be subdued; and then Sparta, left to herself, will be powerless. But if thou wilt not take this advice, I will tell thee what thou mayest look to see. When thou comest to the Peloponnese, thou wilt find a narrow neck of land, where all the Peloponnesians who are leagued against thee will be gathered together; and there thou wilt have to fight bloodier battles than any which thou hast yet witnessed. If, however, thou wilt follow my plan, the Isthmus and the cities of Peloponnese will yield to thee without a battle.»

[7.236] Achaeamenes, who was present, now took the word, and spoke – he was brother to Xerxes, and, having the command of the fleet, feared lest Xerxes might be prevailed upon to do as Demaratus advised «I perceive, O king» (he said), «that thou art listening to the words of a man who is envious of thy good fortune, and seeks to betray thy cause. This is indeed the common temper of the Grecian people – they envy good fortune, and hate power greater than their own. If in this posture of our affairs, after we have lost four hundred vessels by shipwreck, three hundred more be sent away to make a voyage round the Peloponnese, our enemies will be, come a match for us. But let us keep our whole fleet in one body, and it will be dangerous for them to venture on an attack, as they will certainly be no match for us then. Besides, while our sea and land forces advance together, the fleet and army can each help the other; but if they be parted, no aid will come either from thee to the fleet, or from the fleet to thee. Only order thy own matters well, and trouble not thyself to inquire concerning the enemy – where they will fight, or what they will do, or how many they are. Surely they can manage their own concerns without us, as we can ours without them. If the Lacedaemonians come out against the Persians to battle, they will scarce repair the disaster which has befallen them now.»

[7.237] Xerxes replied – «Achaeamenes, thy counsel pleases me well, and I will do as thou sayest. But Demaratus advised what he thought best – only his judgment was not so good as thine. Never will I believe that he does not wish well to my cause; for that is disproved both by his former counsels, and also by the circumstances of the case. A citizen does indeed envy any fellow-citizen who is more lucky than himself, and often hates him secretly; if such a man be called on for counsel, he will not give his best thoughts, unless indeed he be a man of very exalted virtue; and such are but rarely found. But a friend of another country delights in the good fortune of his foreign bond-friend, and will give him, when asked, the best advice in his power. Therefore I warn all men to abstain henceforth from speaking ill of Demaratus, who is my bond-friend.»

[7.238] When Xerxes had thus spoken, he proceeded to pass through the slain; and finding the body of Leonidas, whom he knew to have been the Lacedaemonian king and captain, he ordered that the head should be struck off, and the trunk fastened to a cross. This proves to me most clearly, what is plain also in many other ways – namely, that King Xerxes was more angry with Leonidas, while he was still in life, than with any other mortal. Certes, he would not else have used his body so shamefully. For the Persians are wont to honour those who show themselves valiant in fight more highly than any nation that I know. They, however, to whom the orders were given, did according to the commands of the king.

[7.239] I return now to a point in my History, which at the time I left incomplete. The Lacedaemonians were the first of the Greeks to hear of the king’s design against their country; and it was at this time that they sent to consult the Delphic oracle, and received the answer of which I spoke a while ago. The discovery was made to them in a very strange way. Demaratus, the son of Ariston, after he took refuge with the Medes, was not, in my judgment, which is supported by probability, a well-wisher to the Lacedaemonians. It may be questioned, therefore, whether he did what I am about to mention from good-will or from insolent triumph. It happened that he was at Susa at the time when Xerxes determined to lead his army into Greece; and in this way becoming acquainted with his design, he resolved to send tidings of it to Sparta. So as there was no other way of effecting his purpose, since the danger of being discovered was great, Demaratus framed the following contrivance. He took a pair of tablets, and, clearing the wax away from them, wrote what the king was purposing to do upon the wood whereof the tablets were made; having done this, he spread the wax once more over the writing, and so sent it. By these means, the guards placed to watch the roads, observing nothing but a blank tablet, were sure to give no trouble to the bearer. When the tablet reached Lacedaemon, there was no one, I understand, who could find out the secret, till Gorgo, the daughter of Cleomenes and wife of Leonidas, discovered it, and told the others. «If they would scrape the wax off the tablet,» she said, «they would be sure to find the writing upon the wood.» The Lacedaemonians took her advice, found the writing, and read it; after which they sent it round to the other Greeks. Such then is the account which is given of this matter.
