The Boeotians openly displayed their Macedonian tendencies, even after the expulsion of the Macedonians from Greece; after Flamininus had at their request allowed their countrymen who were in the service of Philip to return home, Brachyllas, the most decided partisan of Macedonia, was elected to the presidency of the Boeotian confederacy, and Flamininus was otherwise irritated in every way.

He bore it with unparalleled patience; but the Boeotians friendly to Rome, who knew what awaited them after the departure of the Romans, determined to put Brachyllas to death, and Flamininus, whose permission they deemed it necessary to ask, at least did not forbid them.

Brachyllas was accordingly killed; upon which the Boeotians were not only content with prosecuting the murderers, but lay in wait for the Roman soldiers passing singly or in small parties through their territories, and killed about 500 of them.
This was too much to be endured; Flamininus imposed on them a fine of a talent for every soldier; and when they did not pay it, he collected the nearest troops and besieged Coronea (558).

Now they betook themselves to entreaty; Flamininus in reality desisted on the intercession of the Achaeans and Athenians, exacting but a very moderate fine from those who were guilty; and although the Macedonian party remained continuously at the helm in the petty province, the Romans met their puerile opposition simply with the forbearance of superior power.

In the rest of Greece Flamininus contented himself with exerting his influence, so far as he could do so without violence, over the internal affairs especially of the newly-freed communities; with placing the council and the courts in the hands of the more wealthy and bringing the anti-Macedonian party to the helm; and with attaching as much as possible the civic commonwealths to the Roman interest, by adding everything, which in each community should have fallen by martial law to the Romans, to the common property of the city concerned.
