Aratus proposed a truce, which Aristippus accepted. Despite this truce, Aratus took the city of Cleonae, controlled by Aristippus. There, he celebrated the Nemean Games, and sold into slavery every Argive found. On hearing of Aristippus' determination to win back Cleonae, Aratus, who was then near Corinth, immediately mobilised a new army, probably by levying volunteers. The Argives feared Achaean intervention and did not dare attack Cleonae, but Aratus did not want to wait longer, and decided on a ploy to lure them. He returned and entered Cleonae before the Argives reached it, then sallied forth the following morning, surprising and routing the Argive army. Aristippus was killed, together with 1,500 other soldiers. It was reported that the Achaeans lost no soldiers at all. And still the victory did not bring the desired result. Aristippus' brother Aristomachus returned to Argos and appointed himself as the new tyrant.
