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
There Lysimachia was taken from the
Aetolian garrison, and Perinthus, which stood in the relation of
clientship to Byzantium, was likewise occupied. Thus the peace was
broken as respected the Byzantines; and as respected the Aetolians,
who had just made peace with Philip, the good understanding was
at least disturbed.
The crossing to Asia was attended with no
difficulties, for Prusias king of Bithynia was in alliance with
Macedonia. By way of recompense, Philip helped him to subdue the
Greek mercantile cities in his territory. Chalcedon submitted.
Cius, which resisted, was taken by storm and levelled with the ground,
and its inhabitants were reduced to slavery--a meaningless barbarity,
which annoyed Prusias himself who wished to get possession of the town
uninjured, and which excited profound indignation throughout the
Greek world.
The Aetolians, whose -strategus- had commanded
in Cius, and the Rhodians, whose attempts at mediation had been
contemptuously and craftily frustrated by the king, were
especially offended.
