History of the Peloponnesian War

Not long after their return from Euboea, they made a truce with the Lacedaemonians and their allies for thirty years, giving up the posts which they occupied in Peloponnese, Nisaea Pegae, Troezen, and Achaia.

In the sixth year of the truce, war broke out between the Samians and Milesians about Priene. Worsted in the war, the Milesians came to Athens with loud complaints against the Samians. In this they were joined by certain private persons from Samos itself, who wished to revolutionize the government.

Accordingly the Athenians sailed to Samos with forty ships and set up a democracy; took hostages from the Samians, fifty boys and as many men, lodged them in Lemnos, and after leaving a garrison in the island returned home.
