As for Ptolemy, his war against the Egyptians followed immediately on these events.
This king, by arming the Egyptians for his war against Antiochus, took a step which was of great service for the time, but which was a mistake as regards the future.
The soldiers, highly proud of their victory at <a class="linkToPlace" target="_blank" href="/place?placename=Raphia&groupId=925&placeId=1656">Raphia</a>, were no longer disposed to obey orders, but were on the look out for a leader and figure-head, thinking themselves well able to maintain themselves as an independent power, an attempt in which they finally succeeded not long afterwards. Antiochus, after making preparations on a large scale during the winter, crossed the Taurus at the beginning of summer and, coming to an understanding with King Attalus, arranged for a joint campaign against Achaeus.
The Aetolians were at first quite satisfied with the terms of their peace with the Achaeans, as the fortune of the war had been adverse to them — they had in fact elected Agelaus of Naupactus as their strategus because they thought he had contributed more than of else to the peace — but in less than no time they began to be dissatisfied
and to blame Agelaus for having cut off all their sources of booty and destroyed their future prospects by making peace with all the Greeks and not with certain states only.
Agelaus, however, put up with these unreasonable complaints and kept them well in hand, so that they were obliged contrary to their nature to practise self-denial.
