History of the Peloponnesian War

After the armistice had expired Cleon persuaded the Athenians to let him sail to the cities in Thrace, with twelve hundred Athenian hoplites and three hundred cavalry, and a larger force of the allies, and thirty ships.

And touching first at Scione, which was still under siege, and taking on from there some hoplites of the garrison, he then sailed down to the port of Cophus, which is not far distant from the city of Torone.

From there, on learning from deserters that Brasidas was not in Torone and that the inhabitants were not a match for him in battle, he advanced with his land-force against the city, but sent ten ships to sail round into the harbour.

And first he arrived at the new wall which Brasidas had built round the city for the purpose of taking in the suburb, having pulled down a part of the old wall and made one city of Torone.
