History of the Peloponnesian War

The same summer Alcibiades, the son of Clinias, being general of the Athenians, by the practice of the Argives and their confederates, went into Peloponnesus, and having with him a few men at arms and archers of Athens and some of the confederates which he took up there as he passed through the country with his army, both ordered such affairs by the way concerning the league as was fit; and coming to the Patreans, persuaded them to build their walls down to the seaside, and purposed to raise another wall himself towards Rhium in Achaia. But the Corinthians, Sicyonians, and such others as this wall would have prejudiced came forth and hindered him.
