Thus the Aeginetans dealt with each other. When the Athenians came, they fought them at sea with seventy ships; the Aeginetans were defeated in the sea-fight and asked for help from the Argives, as they had done before. But this time the Argives would not aid them, holding a grudge because ships of Aegina had been taken by force by Cleomenes and put in on the Argolid coast, where their crews landed with the Lacedaemonians; men from ships of Sicyon also took part in the same invasion. The Argives laid on them the payment of a fine of a thousand talents, five hundred each. The Sicyonians confessed that they had done wrong and agreed to go free with a payment of a hundred talents, but the Aeginetans made no such confession and remained stubborn. For this cause the Argive state sent no one to aid them at their request, but about a thousand came voluntarily, led by a captain whose name was Eurybates, a man who practiced the pentathlon. Most of these never returned, meeting their death at the hands of the Athenians in Aegina; Eurybates himself, their captain, fought in single combat and thus killed three men, but was slain by the fourth, Sophanes the son of Deceles.
