I. When Alexander returned and told him what he had heard from the Athenians, Mardonius set forth from Thessaly and led his army with all zeal against Athens; he also took with him all the people to whose countries he came along the way. The rulers of Thessaly did not repent of what they had already done and were readier than before to further his march. Thorax of Larissa, who had given Xerxes safe-conduct in his flight, now, without any attempt of concealment, opened a passage for Mardonius into Hellas.
II. But when, in the course of its march, the army had come into Boeotia, the Thebans attempted to stay Mardonius, advising him that he could find no country better fitted than theirs for encampment; he should not (they begged) go further, but rather halt there and subdue all Hellas without fighting. [2] As long as the Greeks who were previously in accord remained so, it would be difficult even for the whole world to overcome them by force of arms; “but if you do as we advise,” said the Thebans, “you will without trouble be master of all their battle plans. [3] Send money to the men who have power in their cities, and thereby you will divide Hellas against itself; after that, with your partisans to aid you, you will easily subdue those who are your adversaries.”
III. Such was their counsel, but he would not follow it. What he desired was to take Athens once more; this was partly out of mere perversity, and partly because he intended to signify to the king at Sardis by a line of beacons across the islands that he held Athens. [2] When he came to Attica, however, he found the city as unpopulated as before, for, as he learned, the majority of them were on shipboard at Salamis. So he took the city, but without any of its men. There were ten months between the kings taking of the place and the later invasion of Mardonius.
IV. When Mardonius came to Athens, he sent to Salamis a certain Murychides, a man from Hellespont, bearing the same offer as Alexander the Macedonian had ferried across to the Athenians. [2] He sent this for the second time because although he already knew the Athenians' unfriendly purpose, he expected that they would abandon their stubbornness now that Attica was the captive of his spear and lay at his mercy.
V. For this reason he sent Murychides to Salamis who came before the council and conveyed to them Mardonius message. Then Lycidas, one of the councillors, said that it seemed best to him to receive the offer brought to them by Murychides and lay it before the people. [2] This was the opinion which he declared, either because he had been bribed by Mardonius, or because the plan pleased him. The Athenians in the council were, however, very angry; so too were those outside when they heard of it. They made a ring round Lycidas and stoned him to death. Murychides the Hellespontian, however, they permitted to depart unharmed. [3] There was much noise at Salamis over the business of Lycidas; and when the Athenian women learned what was afoot, one calling to another and bidding her follow, they went on their own impetus to the house of Lycidas and stoned to death his wife and his children
VI. Now this was how the Athenians had crossed over to Salamis. As long as they expected that the Peloponnesian army would come to their aid, they remained in Attica. But when the Peloponnesians took longer and longer to act and the invader was said to be in Boeotia already, they then conveyed all their goods out of harms way and themselves crossed over to Salamis. They also sent envoys to Lacedaemon, who were to upbraid the Lacedaemonians for permitting the barbarian to invade Attica and not helping the Athenians to meet him in Boeotia; and who were to remind the Lacedaemonians of the promises which the Persian had made to Athens if she would change sides, and warn them that the Athenians would devise some means of salvation for themselves if the Lacedaemonians sent them no help.
VII. The Lacedaemonians were at this time celebrating the festival of Hyacinthus, and their chief concern was to give the god his due; moreover, the wall which they were building on the Isthmus was by now getting its battlements. When the Athenian envoys arrived in Lacedaemon, bringing with them envoys from Megara and Plataea, they came before the ephors and said: “The Athenians have sent us with this message: the king of the Medes is ready to give us back our country, and to make us his confederates, equal in right and standing, in all honor and honesty, and to give us whatever land we ourselves may choose besides our own. [2] But we, since we do not want to sin against Zeus the god of Hellas and think it shameful to betray Hellas, have not consented. This we have done despite the fact that the Greeks are dealing with us wrongfully and betraying us to our hurt; furthermore, we know that it is more to our advantage to make terms with the Persians than to wage war with him, yet we will not make terms with him of our own free will. For our part, we act honestly by the Greeks;but what of you, who once were in great dread lest we should make terms with the Persian? Now that you have a clear idea of our sentiments and are sure that we will never betray Hellas, and now that the wall which you are building across the Isthmus is nearly finished, you take no account of the Athenians, but have deserted us despite all your promises that you would withstand the Persian in Boeotia, and have permitted the barbarian to march into Attica. [2] For the present, then, the Athenians are angry with you since you have acted in a manner unworthy of you. Now they ask you to send with us an army with all speed, so that we may await the foreigner's onset in Attica; since we have lost Boeotia, in our own territory the most suitable place for a battle is the Thriasian plain.”
VIII. When the ephors heard that, they delayed answering till the next day, and again till the day after. This they did for ten days, putting it off from day to day. In the meantime all the Peloponnesians were doing all they could to fortify the Isthmus, and they had nearly completed the task. [2] I cannot say for certain why it was that when Alexander the Macedonian came to Athens the Lacedaemonians insisted that the Athenians should not join the side of the Persian, yet now took no account of that; it may be that with the Isthmus fortified, they thought they had no more need of the Athenians, whereas when Alexander came to Attica, their wall was not yet built and they were working at this in great fear of the Persians.
IX. The nature of their response was as follows: on the day before the final hearing of the Athenian delegation, Chileus, a man of Tegea, who had more authority with the Lacedaemonians than any other of their guests, learned from the ephors all that the Athenians had said. [2] Upon hearing this he, as the tale goes, said to the ephors, “Sirs, if the Athenians are our enemies and the barbarians allies, then although you push a strong wall across the Isthmus, a means of access into the Peloponnese lies wide open for the Persian. No, give heed to what they say before the Athenians take some new resolve which will bring calamity to Hellas.”
X. This was the counsel he gave the ephors, who straightway took it to heart. Without saying a word to the envoys who had come from the cities, they ordered five thousand Spartans to march before dawn. Seven helots were appointed to attend each of them, and they gave the command to Pausanias son of Cleombrotus. [2] The leader's place rightfully belonged to Pleistarchus son of Leonidas, but he was still a boy, and Pausanias his guardian and cousin. Cleombrotus, Pausanias' father and Anaxandrides' son, was no longer living.
