233. The Thebans however, of whom the commander was Leontiades, being with the Hellenes had continued for some time to fight against the king’s army, constrained by necessity; but when they saw that the fortunes of the Persians were prevailing, then and not before, while the Hellenes with Leonidas were making their way with speed to the hillock, they separated from these and holding out their hands came near to the Barbarians, saying at the same time that which was most true, namely that they were on the side of the Medes and that they had been among the first to give earth and water to the king; and moreover that they had come to Thermopylai constrained by necessity, and were blameless for the loss which had been inflicted upon the king: so that thus saying they preserved their lives, for they had also the Thessalians to bear witness to these words. However, they did not altogether meet with good fortune, for some had even been slain as they had been approaching, and when they had come and the Barbarians had them in their power, the greater number of them were branded by command of Xerxes with the royal marks, beginning with their leader Leontiades, the same whose son Eurymachos was afterwards slain by the Plataians, when he had been made commander of four hundred Thebans and had seized the city of the Plataians.1204
234. Thus did the Hellenes at Thermopylai contend in fight; and Xerxes summoned Demaratos and inquired of him, having first said this: “Demaratos, thou art a good man; and this I conclude by the truth of thy words, for all that thou saidest turned out so as thou didst say. Now, however, tell me how many in number are the remaining Lacedaemonians, and of them how many are like these in matters of war; or are they so even all of them?” He said: “O king, the number of all the Lacedaemonians is great and their cities are many, but that which thou desirest to learn, thou shalt know. There is in Lacedaemon the city of Sparta, having about eight thousand men; and these are all equal to those who fought here: the other Lacedaemonians are not equal to these, but they are good men too.” To this Xerxes said: “Demaratos, in what manner shall we with least labour get the better of these men? Come set forth to us this; for thou knowest the courses of their counsels,1205 seeing that thou wert once their king.” 235. He made answer: “O king, if thou dost in very earnest take counsel with me, it is right that I declare to thee the best thing. What if thou shouldest send three hundred ships from thy fleet to attack the Laconian land? Now there is lying near it an island named Kythera, about which Chilon, who was a very wise man among us, said that it would be a greater gain for the Spartans that it should be sunk under the sea than that it should remain above it; for he always anticipated that something would happen from it of such a kind as I am now setting forth to thee: not that he knew of thy armament beforehand, but that he feared equally every armament of men. Let thy forces then set forth from this island and keep the Lacedaemonians in fear; and while they have a war of their own close at their doors, there will be no fear for thee from them that when the remainder of Hellas is being conquered by the land-army, they will come to the rescue there. Then after the remainder of Hellas has been reduced to subjection, from that moment the Lacedaemonian power will be left alone and therefore feeble. If however thou shalt not do this, I will tell thee what thou must look for. There is a narrow isthmus leading to the Peloponnese, and in this place thou must look that other battles will be fought more severe
