History of the Peloponnesian War

Meanwhile the Athenians in the hundred vessels, still cruising around the Peloponnese, took Sollium, a town belonging to the Corinthians, and gave it up to the Palaereans alone of the Acarnanians, to enjoy the territory and city; and having stormed Astacus, of which Evarchus was tyrant, they expelled him, and won the place for their confederacy.

They then sailed to the island of Cephallenia, and brought it over to their side without fighting. Cephallenia lies opposite Acarnania and Leucas, and consists of four states, the Paleans, Cranians, Samaeans, and Pronaeans. Not long after, the ships returned to Athens.
