[Sidenote: Euergetes jealous of the Macedonian policy of Aratus, helps Cleomenes.] +51.+ But when Ptolemy, despairing of retaining the league’s friendship, began to furnish Cleomenes with supplies,—which he did with a view of setting him up as a foil to Antigonus, thinking the Lacedaemonians offered him better hopes than the Achaeans of being able to thwart the policy of the Macedonian kings; and when the Achaeans themselves had suffered three defeats,—one at Lycaeum in an engagement with Cleomenes whom they had met on a march; and again in a pitched battle at Ladocaea in the territory of Megalopolis, in which Lydiades fell; and a third time decisively at a place called Hecatomboeum in the territory of Dyme where their whole forces had been engaged,—after these misfortunes, no further delay was possible, and they were compelled by the force of circumstances to appeal unanimously to Antigonus. Thereupon Aratus sent his son to Antigonus, and ratified the terms of the subvention. The great difficulty was this: it was believed to be certain that the king would send no assistance, except on the condition of the restoration of the Acrocorinthus, and of having the city of Corinth put into his hands as a base of operations in this war; and on the other hand it seemed impossible that the Achaeans should venture to put the Corinthians in the king’s power against their own consent. The final determination of the matter was accordingly postponed, that they might investigate the question of the securities to be given to the king. [Sidenote: The Achaeans offer to surrender the Acrocorinthus to Antigonus.] +52.+ Meanwhile, on the strength of the dismay caused by his successes, Cleomenes was making an unopposed progress through the cities, winning some by persuasion and others by threats. In this way, he got possession of Caphyae, Pellene, Pheneus, Argos, Phlius, Cleonae, Epidaurus, Hermione, Troezen, and last of all Corinth, while he personally commanded a siege of Sicyon. But this in reality relieved the Achaeans from a very grave difficulty. For the Corinthians by ordering Aratus, as Strategus of the league, and the Achaeans to evacuate the town, and by sending messages to Cleomenes inviting his presence, gave the Achaeans a ground of action and a reasonable pretext for moving. Aratus was quick to take advantage of this; and, as the Achaeans were in actual possession of the Acrocorinthus, he made his peace with the royal family of Macedonia by offering it to Antigonus; and at the same time gave thus a sufficient guarantee for friendship in the future, and further secured Antigonus a base of operations for the war with Sparta.
