38.  Mictio and Xenoclides, who were now, since the banishment of Euthymidas, in possession of the supreme power, either of themselves suspected the matter, or received some information of it, and were at first so greatly terrified, that they saw no prospect of safety but in flight; but afterwards, when their fright subsided, and they considered that, by such a step, they would betray and desert not only their country, but the Roman alliance, they applied their minds to the following plan.  It happened that, at that very time, there was a solemn anniversary festival, celebrated at Eretria, in honour of Diana Amarynthis, which was always attended by great numbers, not only of the natives, but also of the Carystians:  thither they sent envoys to beseech the Eretrians and Carystians, “as having been born in the same isle, to compassionate their situation; and, at the same time, to show their regard to the friendship of Rome:  not to suffer Chalcis to become the property of the Aetolians; that if they should possess Chalcis they would obtain possession of all Euboea:  and to remind them, that they had found the Macedonians grievous masters, but that the Aetolians would be much more intolerable.”  The consideration of the Romans chiefly influenced those states, as they had lately experienced both their bravery in war, and their justice and liberality in success.  Both states, therefore, armed, and sent the main strength of their young men.  To these the people of Chalcis intrusted the defence of the walls, and they themselves, with their whole force, crossed the Euripus, and encamped at Salganea.  From that place they despatched, first a herald, and afterwards ambassadors, to ask the Aetolians, for what word or act of theirs, friends and allies came thus to invade them.  Thoas, commander of the Aetolians, answered, that “he came not to attack them, but to deliver them from the Romans; that they were fettered at present with a brighter chain indeed, but a much heavier one, than when they had a Macedonian garrison in their citadel.”  The men of Chalcis replied that “they were neither under bondage to any one, nor in need of the protection of any.”  The ambassadors then withdrew from the meeting, and returned to their countrymen.  Thoas and the Aetolians (who had no other hopes than in a sudden surprise, and were by no means in a capacity to undertake a regular war, and the siege of a city so well secured against any attack from the land or the sea) returned home.  Euthymidas, on hearing that his countrymen were encamped at Salganea, and that the Aetolians had retired, went back from Thebes to Athens.  Herodorus, after waiting several days at Atalanta, attentively watching for the concerted signal in vain, sent an advice-boat to learn the cause of the delay; and, understanding that the enterprise was abandoned by his associates, returned to Thronium from whence he had come.
