Then as the armies were just about the join battle, the Corinthians first, considering with themselves that they were not acting rightly, changed their minds and departed; and after that Demaratos the son of Ariston did the same, who was king of the Spartans as well as Cleomenes, though he had joined with him in leading the army out from Lacedemon and had not been before this at variance with Cleomenes. In consequence of this dissension a law was laid down at Sparta that it should not be permitted, when an army went out, that both the kings should go with it, for up to this time both used to go with it, and that as one of the kings was set free from service, so one of the sons of Tyndareus 64 also should be left behind; for before this time both of these two were called upon by them for help and went with the armies.

At this time then in Eleusis the rest of the allies, seeing that the kings of the Lacedemonians did not agree and also that the Corinthians had deserted their place in the ranks, themselves too departed and got them away quickly. And this was the fourth time that the Dorians had come to Attica, twice having invaded it to make war against it, and twice to help the mass of the Athenian people,—first when they at the same time colonised Megara (this expedition may rightly be designated as taking place when Codros was king of the Athenians), for the second and third times when they came making expeditions from Sparta to drive out the sons of Peisistratos, and fourthly on this occasion, when Cleomenes at the head of the Peloponnesians invaded Eleusis: thus the Dorians invaded Athens then for the fourth time.

This army then having been ingloriously broken up, the Athenians after that, desiring to avenge themselves, made expedition first against the Chalkidians; and the Boeotians came to the Euripos to help the Chalkidians. The Athenians, therefore, seeing those who had come to help, 6401 resolved first to attack the Boeotians before the Chalkidians. Accordingly they engaged battle with the Boeotians, and had much the better of them, and after having slain very many they took seven hundred of them captive. On this very same day the Athenians passed over into Euboea and engaged battle with the Chalkidians as well; and having conquered these also, they left four thousand holders of allotments in the land belonging to the "Breeders of Horses": 65 now the wealthier of the Chalkidians were called the Breeders of Horses. And as many of them as they took captive, they kept in confinement together with the Boeotians who had been captured, bound with fetters; and then after a time they let them go, having fixed their ransom at two pounds of silver apiece: 66 but their fetters, in which they had been bound, they hung up on the Acropolis; and these were still existing even to my time hanging on walls which had been scorched with fire by the Mede, 67 and just opposite the sanctuary which lies towards the West. The tenth part of the ransom also they dedicated for an offering, and made of it a four-horse chariot of bronze, which stands on the left hand as you enter the Propylaia in the Acropolis, and on it is the following inscription:
