History of the Peloponnesian War

The Athenians, being yet with their hundred galleys about Peloponnesus, took Solium, a town that belonged to the Corinthians, and put the Palaerenses only, of all the Acarnanians, into the possession both of the town and territory. Having also by force taken Astacus from the tyrant Euarchus, they drave him thence and joined the place to their league.

From thence they sailed to Cephalonia and subdued it without battle (this Cephalonia is an island lying over against Acarnania and Leucas and hath in it these four cities, the Pallenses, Cranii, Samaei, and Pronaei) and not long after returned with their fleet to Athens.

About the end of the autumn of this summer the Athenians, both themselves and the strangers that dwelt amongst them, with the whole power of the city, under the conduct of Pericles the son 31antippus, invaded the territory of Megara. And those Athenians likewise that had been with the hundred galleys about Peloponnesus, in their return, being now at Aegina, hearing that the whole power of the city was gone into Megaris, went and joined them.
