History of the Peloponnesian War

Meanwhile the Athenians in the hundred ships, who were still operating on the Peloponnesian coast, took Sollium, a town belonging to the Corinthians, which they then handed over, the territory as well as the city, to the people of Palaerus in Acarnania, for their exclusive occupation. They also stormed Astacus, which Euarchus ruled as tyrant, drove him out, and incorporated the place in their confederacy.

Sailing then to the island of Cephallenia, they brought it over to their side without a battle. Now Cephallenia lies over against Acarnania and Leucas and is a union of four communities, the Palians, Cranians, Samaeans, and Pronnians. And not long afterwards the ships withdrew to Athens.
