Settlement of Greece - Conflicts and Peace with the Aetolians
European Greece also had been agitated by this Asiatic war, and needed reorganization. The Aetolians, who had not yet learned to reconcile themselves to their insignificance, had, after the armistice concluded with Scipio in the spring of 564, rendered intercourse between Greece and Italy difficult and unsafe by means of their Cephallenian corsairs; and not only so, but even perhaps while the armistice yet lasted, they, deceived by false reports as to the state of things in Asia, had the folly to place Amynander once more on his Athamanian throne, and to carry on a desultory warfare with Philip in the districts occupied by him on the borders of Aetolia and Thessaly, in the course of which Philip suffered several discomfitures.
After this, as a matter of course, Rome replied to their request for peace by the landing of the consul Marcus Fulvius Nobilior. He arrived among the legions in the spring of 565, and after fifteen days' siege gained possession of Ambracia by a capitulation honourable for the garrison; while simultaneously the Macedonians, Illyrians, Epirots, Acarnanians, and Achaeans fell upon the Aetolians. There was no such thing as resistance in the strict sense; after repeated entreaties of the Aetolians for peace the Romans at length desisted from the war, and granted conditions which must be termed reasonable when viewed with reference to such pitiful and malicious opponents.
