History of the Peloponnesian War

After the truce was expired, Cleon prevailed with the Athenians to be sent out with a fleet against the cities lying upon Thrace. He had with him of Athenians twelve hundred men of arms and three hundred horsemen, of confederates more, and thirty galleys.

And first arriving at Scione, which was yet besieged, he took aboard some men of arms of those that kept the siege and sailed into the haven of the Colophonians, not far distant from the city of Torone.

And there, having heard by fugitives that Brasidas was not in Torone nor those within sufficient to give him battle, he marched with his army to the city and sent ten of his galleys about into the haven.

And first he came to the new wall, which Brasidas had raised about the city to take in the suburbs, making a breach in the old wall that the whole might be one city.
