Egypt had enough to do in defending herself against the nearer enemy in Syria, and was obliged to leave her possessions in Asia Minor and the Cyclades undefended when Philip threw himself upon these as his share of the spoil.

In the year in which Carthage concluded peace with Rome (553), Philip ordered a fleet equipped by the towns subject to him to take on board troops, and to sail along the coast of Thrace.

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.
