Please note that Mommsen uses the AUC chronology (Ab Urbe Condita), i.e. from the founding of the City of Rome. You can use this reference table to have the B.C. dates
Even the Aetolians, when their
corps shut up in Heraclea had been compelled after obstinate
resistance to capitulate, attempted to make their peace with the
sorely provoked Romans; but the stringent demands of the Roman consul,
and a consignment of money seasonably arriving from Antiochus,
emboldened them once more to break off the negotiations and to sustain
for two whole months a siege in Naupactus.
The town was already
reduced to extremities, and its capture or capitulation could not have
been long delayed, when Flamininus, constantly striving to save every
Greek community from the worst consequences of its own folly and
from the severity of his ruder colleagues, interposed and arranged in
the first instance an armistice on tolerable terms. This terminated,
at least for the moment, armed resistance in Greece.
