The History of the Grecian War (1.105.1-1.105.3)

The Athenians came also with a fleet to Halias and landing their soldiers fought by land with the Corinthians and Epidaurians, and the Corinthians had the victory. After this, the Athenians fought by sea against the fleet of the Peloponnesians at Cecryphaleia, and the Athenians had the victory.

After this again, the war being on foot of the Athenians against the Aeginetae, a great battle was fought between them by sea upon the coast of Aegina, the confederates of both sides being at the same, in which the Athenians had the victory, and having taken seventy galleys landed their army and besieged the city under the conduct of Leocrates the son of Stroebus.

After this, the Peloponnesians, desiring to aid the Aeginetae, sent over into Aegina itself three hundred men of arms of the same that had before aided the Corinthians and Epidaurians and with other forces seized on the top of Geraneia. And the Corinthians and their confederates came down from thence into the territory of Megara, supposing that the Athenians, having much of their army absent in Aegina and in Egypt, would be unable to aid the Megareans or, if they did, would be forced to rise from before Aegina.
