Accordingly, Aratus took fifteen hundred soldiers from Antigonus and sailed to Epidaurus. Aristotle, however, did not await his coming, but at the head of the citizens made an attack upon the garrison of the citadel; and Timoxenus came to his aid from Sicyon with the Achaean army.
It was about midnight when Cleomenes heard of these things, and summoning Megistonoüs, he angrily ordered him to go at once to Argos with assistance; for it was Megistonoüs who had given him most assurances of the fidelity of the Argives, and had thereby prevented him from expelling the suspected citizens. After sending off Megistonoüs, then, with two thousand soldiers, he himself kept watch upon Antigonus and tried to encourage the Corinthians, telling them that there was no great trouble at Argos, but only a slight disturbance made by a few men.
