38. Micythio and Xenoclides, in whose hands rested supreme power¹ after Euthymidas had been expelled from Chalcis, whether they formed their own suspicions or the plot was betrayed, at first were alarmed and placed no trust in anything but flight; then, when their terror subsided and they realized that they would be deserting and abandoning not only their country but also. [2] the Roman alliance, they increased their courage by the following scheme. [3] It happened that at this time there was an annual festival at Eretria in honour of Diana Amarynthis, which crowds both of the natives and of the Carystii attend.² [4] They sent there men to beg the people of Eretria and Carystus, born on the same island, to pity their plight and respect the Roman alliance; let them not permit Chalcis to become the property of the Aetolians; they would control Euboea if once they controlled Chalcis; [5] the Macedonians had been hard to endure as masters; the Aetolians would be far less easy to bear. [6] Regard for the Romans had especial influence with the states, which had recently had experience of both their valour in war and their justice and kindness in [p. 115]victory. Therefore whatever strength in young men³ each state had it armed and sent. [7] When the townspeople had turned over to them the defence of the walls of Chalcis, they themselves with all their forces crossed the Euripus and pitched camp near Salganeus. [8] Thence first a herald and then ambassadors were sent to the Aetolians to inquire what word or action on their part had brought allies and friends to attack them. [9] Thoas, the Aetolian chieftain, replied that they were coming, not to besiege them, but to set them free from the Romans; now a more glittering chain, but a far heavier one, bound them than when they had a Macedonian garrison in their citadel. [10] The Chalcidenses, however, denied that they were slaves to any man or that they needed the protection of anyone. [11] So, leaving the conference, the ambassadors returned to their people; Thoas and the Aetolians, inasmuch as they had placed all their hopes on the chance of catching them off guard, since they were by no [12??] means equal to a regular war and the siege of a city well fortified by sea and land, returned home. [13] After Euthymidas learned that the camp of his countrymen had been pitched at Salganea and that the Aetolians had gone, he himself also returned from Thebes to Athens, and Herodorus, [14??] after waiting several days in vain, anxiously watching from Atalante for a signal, sending out a scouting vessel to ascertain what was causing the delay, when he learned that the attempt had been abandoned by his allies, returned to Thronium whence he had come.
