History of the Peloponnesian War

After the armistice had expired, Cleon, having persuaded the Athenians to the measure, led an expedition against the Thrace-ward towns, with twelve hundred heavy-armed, and three hundred cavalry of the Athenians, a larger force of the allies, and thirty ships.

After landing in the first place at Scione, which was still being besieged, and taking thence some heavy-armed from the garrison, he sailed into the port of the Colophonians, belonging to the Toronaeans, and at no great distance from their city.

Thence, having learned from deserters both that Brasidas was not in Torone, and that those who were in it were not strong enough to give him battle, with his land forces he marched against the city, while he sent ten ships to sail round into the harbour.

First, then, he came to the fortifications which Brasidas had raised anew round the city, from a wish to include the suburb, and so by taking down a part of the original wall had made it one city.
