History of the Peloponnesian War

for they themselves would as far as possible give them no opportunity of using the latter, and the narrow space would prevent them from deploying. But on the other hand they themselves would chiefly employ that method of crashing into their opponents prow to prow which had formerly been imputed to the ignorance of their pilots, because they would find it greatly to their advantage to do so;

for it would not be possible for the Athenians, if forced out of line, to back water in any other direction than towards the land, and that, too, for only a short distance and to a short stretch of shore—the space in front of their own camp—inasmuch as the Syracusans would command the rest of the harbour.

And the enemy, if they were forced to yield at any point, would be driven together into a small space and all to the same point, so that they would fall foul of each other and be thrown into confusion—the very thing that caused the Athenians most damage in all the fighting there, since it was not possible for them, as it was for the Syracusans, to back water to any part of the harbour. The Syracusans saw, moreover, that the Athenians would not be able to sail round into open water, since they themselves would control not only their entrance into the harbour from the sea outside, but also their backing out of the harbour into the sea, especially as Plemmyrium would be hostile to them and the mouth of the harbour was not large.
