History of the Peloponnesian War

Immediately after this, when Dercylidas had completed his march overland from Miletus, Abydus on the Hellespont revolted to Dercylidas and Pharnabazus, as did Lampsacus also two days afterwards.

But Strombichides, learning of this, came from Chios with all speed to the rescue with twenty-four Athenian ships, of which some were transports and carried hoplites; and having defeated in battle the Lampsacenes who came out against him and taken at the first assault the city of Lampsacus, which was without walls, he made booty of goods and slaves but restored the free men to their homes, and then went against Abydus.

And when its inhabitants would not yield and he was unable to take the city by assault, he sailed back to the coast opposite Abydus and made Sestus, a city of the Chersonese which the Persians once held, a fortress and watch-station for the control of the whole Hellespont.
