History of the Peloponnesian War

And what was before thought to be want of skill in masters, namely, to charge stein to stem, was the very method they would chiefly adopt; for they would have the advantage in it; as the Athenians, if forced out of the line, would have no means of backing water in any direction but towards shore, and that, too, at only a short distance from them, and for a short space, namely, just opposite their own encampment. The rest of the harbour they should themselves command;

and the enemy, if forced at any point, by crowding together into a confined space, and all to the same point, would run foul of each other, and be thrown into confusion; (the very thing, indeed, which most hurt the. Athenians in all their sea-fights, since they had not, like the Syracusans, the power of retreating over the whole harbour.) And as for making a circuit into clearer sea-room, since they themselves commanded the entrance from, and the retreat into, the open deep, they would not be able to do it; especially as Plemyrium would be hostile to them, and the mouth of the harbour was not large.
