History of the Peloponnesian War

The Athenians, being informed of their intentions, also sailed from Samos and captured the six ships that were on guard at Triopium, though their crews escaped. After this they sailed to Cnidos, and attacking the city, which was without walls, almost captured it.

The next day they made a second assault, but as the inhabitants had strengthened their defences during the night and had been reinforced by the men who had escaped from the ships at Triopium, the Athenians could not do so much damage as before, and so they withdrew and, after ravaging the territory of the Cnidians, sailed back to Samos.
