Antigonus tried to recover, building an alliance with Athens, Argos and Sicyon, but Alexander managed to pull Sicyon over to his side and subsequently allied himself with the Achaean League. Challenged by a contemporary offensive of his Ptolemaic rival in the Cyclades, Antigonus was unable to protect his allies. In 249 Alexander carried victories over Athens and Argos and the following year he possibly forced his enemies to accept a truce.
