Agis and Cleomenes

But now only a little time had elapsed, and they had as yet barely resumed their native customs and reentered the track of their famous discipline, when, as if before the very eyes of Lycurgus and with his cooperation, they gave abundant proof of valour and obedience to authority, by recovering the leadership of Hellas for Sparta and making all Peloponnesus their own again.

Thus Argos was taken by Cleomenes, and immediately afterwards Cleonae and Phlius came over to him. When this happened, Aratus was at Corinth, holding a judicial examination of those who were reputed to favour the Spartan cause. The unexpected tidings threw him into consternation, and perceiving that the city was leaning towards Cleomenes and wished to be rid of the Achaeans, he summoned the citizens into the council-hall, and then slipped away unnoticed to the city gate. There his horse was brought to him, and mounting it he fled to Sicyon.
