Mnasilochus, and some others of his faction, were studiously included in this embassy; who, sending private messengers to desire the king to bring up his army, wasted time on purpose; so that the ambassadors had scarcely set out, when Antiochus appeared in the territory, and presently at the gates of the city; and, while those who were not concerned in the plot were all in hurry and confusion, and hastily called the young men to arms, he was conducted into the place by Clitus and Mnasilochus.

One party of the citizens now joined him through inclination, and those who were of different sentiments were compelled by fear to attend him.
He then calmed their apprehensions by a discourse full of mildness; and in the hope of experiencing his clemency, which was reported abroad, several of the states of Acarnania went over to his side.

From Medio he went to Thurium, whither he had sent on before him the same Mnasilochus, and his colleagues in the embassy.

But the detection of the treachery practised at Medio rendered the Thurians more cautious, but not more timid.

They answered him explicitly, that they would form no new alliance without the approbation of the Romans: they then shut their gates, and posted soldiers on the walls.
