203. In addition to these the Locrians of Opus had been summoned to come in their full force, and of the Phokians a thousand: for the Hellenes had of themselves sent a summons to them, saying by messengers that they had come as forerunners of the others, that the rest of the allies were to be expected every day, that their sea was safely guarded, being watched by the Athenians and the Eginetans and by those who had been appointed to serve in the fleet, and that they need fear nothing: for he was not a god, they said, who was coming to attack Hellas, but a man; and there was no mortal, nor would be any, with those fortunes evil had not been mingled at his very birth, and the greatest evils for the greatest men; therefore he also who was marching against them, being mortal, would be destined to fail of his expectation. They accordingly, hearing this, came to the assistance of the others at Trachis.

204. Of these troops, although there were other commanders also according to the State to which each belonged, yet he who was most held in regard and who was leader of the whole army was the Lacedemonian Leonidas son of Anaxandrides, son of Leon, son of Eurycratides, son of Anaxander, son of Eurycrates, son of Polydoros, son of Alcamenes, son of Teleclos, son of Archelaos, son of Hegesilaos, son of Doryssos, son of Leobotes, son of Echestratos, son of Agis, son of Eurysthenes, son of Aristodemos, son of Aristomachos, son of Cleodaios, son of Hyllos, son of Heracles; who had obtained the kingdom of Sparta contrary to expectation.

205. For as he had two brothers each older than himself, namely Cleomenes and Dorieos, he had been far removed from the thought of becoming king. Since however Cleomenes had died without male child, and Dorieos was then no longer alive, but he also had brought his life to an end in Sicily, [210] thus the kingdom came to Leonidas, both because was of elder birth than Cleombrotos (for Cleombrotos was the youngest of the sons of Anaxandrides) and also because he had in marriage the daughter of Cleomenes. He then at this time went to Thermopylai, having chosen the three hundred who were appointed by law [211] and men who chanced to have sons; and he took with him besides, before he arrived, those Thebans whom I mentioned when I reckoned them in the number of the troops, of whom the commander was Leontiades the son of Eurymachos: and for this reason Leonidas was anxious to take up these with him of all the Hellenes, namely because accusations had been strongly brought against them that they were taking the side of the Medes; therefore he summoned them to the war, desiring to know whether they would send troops with them or whether they would openly renounce the alliance of the Hellenes; and they sent men, having other thoughts in their mind the while.

206. These with Leonidas the Spartans had sent out first, in order that seeing them the other allies might join in the campaign, and for fear that they also might take the side of the Medes, if they heard that the Spartans were putting off their action. Afterwards, however, when they had kept the festival, (for the festival of the Carneia stood in their way), they intended then to leave a garrison in Sparta and to come to help in full force with speed: and just so also the rest of the allies had thought of doing themselves; for it chanced that the Olympic festival fell at the same time as these events. Accordingly, since they did not suppose that the fighting in Thermopylai would so soon be decided, they sent only the forerunners of their force.

207. These, I say, had intended to do thus: and meanwhile the Hellenes at Thermopylai, when the Persian had come near to the pass, were in dread, and deliberated about making retreat from their position. To the rest of the Peloponnesians then it seemed best that they should go to the Peloponnese and hold the Isthmus in guard; but Leonidas, when the Phokians and Locrians were indignant at this opinion, gave his vote for remaining there, and for sending at the same time messengers to the several States bidding them to come up to help them, since they were but few to repel the army of the Medes.

208. As they were thus deliberating, Xerxes sent a scout on horseback to see how many they were in number and what they were doing; for he had heard while he was yet in Thessaly that there had been assembled in this place a small force, and that the leaders of it were Lacedemonians together with Leonidas, who was of the race of Heracles. And when the horseman had ridden up towards their camp, he looked upon them and had a view not indeed of the whole of their army, for of those which were posted within the wall, which they had repaired and were keeping a guard, it was not possible to have a view, but he observed those who were outside, whose station was in front of the wall; and it chanced at that time that the Lacedemonians were they who were posted outside. So then he saw some of the men practising athletic exercises and some combing their long hair: and as he looked upon these things he marvelled, and at the same time he observed their number: and when he had observed all exactly, he rode back unmolested, for no one attempted to pursue him and he found himself treated with much indifference. And when he returned he reported to Xerxes all that which he had seen.

209. Hearing this Xerxes was not able to conjecture the truth about the matter, namely that they were preparing themselves to die and to deal death to the enemy so far as they might; but it seemed to him that they were acting in a manner merely ridiculous; and therefore he sent for Demaratos the son of Ariston, who was in his camp, and when he came, Xerxes asked him of these things severally, desiring to discover what this was which the Lacedemonians were doing: and he said: "Thou didst hear from my mouth at a former time, when we were setting forth to go against Hellas, the things concerning these men; and having heard them thou madest me an object of laughter, because I told thee of these things which I perceived would come to pass; for to me it is the greatest of all ends to speak the truth continually before thee, O king. Hear then now also: these men have come to fight with us for the passage, and this is it that they are preparing to do; for they have a custom which is as follows;—whenever they are about to put their lives in peril, then they attend to the arrangement of their hair. Be assured however, that if thou shalt subdue these and the rest of them which remain behind in Sparta, there is no other race of men which will await thy onset, O king, or will raise hands against thee: for now thou art about to fight against the noblest kingdom and city of those which are among the Hellenes, and the best men." To Xerxes that which was said seemed to be utterly incredible, and he asked again a second time in what manner being so few they would fight with his host. He said; "O king, deal with me as with a liar, if thou find not that these things come to pass as I say."

210. Thus saying he did not convince Xerxes, who let four days go by, expecting always that they would take to flight; but on the fifth day, when they did not depart but remained, being obstinate, as he thought, in impudence and folly, he was enraged and sent against them the Medes and the Kissians, charging them to take the men alive and bring them into his presence. Then when the Medes moved forward and attacked the Hellenes, there fell many of them, and others kept coming up continually, and they were not driven back, though suffering great loss: and they made it evident to every man, and to the king himself not least of all, that human beings are many but men are few. This combat went on throughout the day:

211, and when the Medes were being roughly handled, then these retired from the battle, and the Persians, those namely whom the king called "Immortals," of whom Hydarnes was commander, took their place and came to the attack, supposing that they at least would easily overcome the enemy. When however these also engaged in combat with the Hellenes, they gained no more success than the Median troops but the same as they, seeing that they were fighting in a place with a narrow passage, using shorter spears than the Hellenes, and not being able to take advantage of their superior numbers. The Lacedemonians meanwhile were fighting in a memorable fashion, and besides other things of which they made display, being men perfectly skilled in fighting opposed to men who were unskilled, they would turn their backs to the enemy and make a pretence of taking to flight; and the Barbarians, seeing them thus taking a flight, would follow after them with shouting and clashing of arms: then the Lacedemonians, when they were being caught up, turned and faced the Barbarians; and thus turning round they would slay innumerable multitudes of the Persians; and there fell also at these times a few of the Spartans themselves. So, as the Persians were not able to obtain any success by making trial of the entrance and attacking it by divisions and every way, they retired back.

212. And during these onsets it is said that the king, looking on, three times leapt up from his seat, struck with fear for his army. Thus they contended then: and on the following day the Barbarians strove with no better success; for because the men opposed to them were few in number, they engaged in battle with the expectation that they would be found to be disabled and would not be capable any longer of raising their hands against them in fight. The Hellenes however were ordered by companies as well as by nations, and they fought successively each in turn, excepting the Phokians, for these were posted upon the mountain to guard the path. So the Persians, finding nothing different from that which they had seen on the former day, retired back from the fight.
