Then, since he despaired of success in this way, he openly invaded the territory of Argos with his army and ravaged it; and in a fierce battle with Aristippus at the river Chares, he was accused of abandoning the struggle and throwing away the victory. For although the rest of his forces admittedly had the upper hand and had gone far on ahead in pursuit, he himself, not so much because he was ousted from his position by his opponents, as out of mistrust of success and in utter fear, withdrew in disorder to his camp.
But when the rest of his army came back from the pursuit and were indignant because, though they had routed the enemy and slain far more of them than they had lost of their own number, they had suffered the vanquished to erect a trophy over the victors, Aratus was ashamed and determined again to fight out the question of the trophy, and on the next day but one put his army once more in battle array.
However, on perceiving that the forces of the tyrant were more numerous than before and more courageous in their resistance, he would not venture a decisive battle, but withdrew after being allowed to take up his dead under a truce. Nevertheless, by his skill in dealing with men and public affairs, and by the favour in which he stood, he retrieved this failure, brought Cleonae into the Achaean League, and celebrated the Nemean games in that city, on the ground that it had an ancient and more fitting claim upon them.
But the games were also celebrated at Argos, and then for the first time the privilege of asylum and safe-conduct which had been granted to contestants in the games was violated, since the Achaeans treated as enemies and sold into slavery all contestants in the games at Argos whom they caught travelling through their territory. So fierce and implacable was Aratus in his hatred of tyrants.
