Nor was he mistaken in that opinion; for no sooner was Heraclea reduced, than a message came to him to desist from the assault; because "it was more reasonable that the Roman soldiers, who had fought the Aetolians in the field, should reap the fruits of the victory." Thus was Lamia relieved, and the misfortune of a neighbouring city proved the means of its escaping a like disaster.

A few days before the capture of Heraclea, the Aetolians, having assembled a council at Hypata, sent ambassadors to Antiochus, among whom was Thoas, the same who had been sent on the former occasion.
Their instructions were in the first place, to request the king again to assemble his land and marine forces and cross over into Greece; and, in the next place, if any circumstance should detain him, then to send them supplies of men and money.

They were to remind him, that "it concerned his dignity and his honour, not to abandon his allies; and it likewise concerned the safety of his kingdom, not to leave the Romans at full leisure, after ruining the nation of the Aetolians, to carry their whole force into Asia." What they said was true, and therefore made the deeper impression on the king; in consequence of which, he immediately supplied the ambassadors with the money requisite for the exigencies of the war, and assured them, that he would send them succours both of troops and ships.

One of the ambassadors, namely, Thoas, he kept with him, by no means against his will, as he hoped that, being present, he might induce the performance of the king's promises.

But the loss of Heraclea entirely broke the spirits of the Aetolians; insomuch that, within a few days after they had sent ambassadors into Asia for the purpose of renewing the war, and inviting the king, they threw aside all warlike designs, and despatched deputies to the consul to sue for peace.
