Meanwhile the Syracusans hearing of their approach resolved to make a second attempt with their fleet and their other forces on shore, which they had been collecting for this very purpose in order to do something before their arrival.
In addition to other improvements suggested by the former sea-fight which they now adopted in the equipment of their navy, they cut down their prows to a smaller compass to make them more solid and made their cheeks stouter, and from these let stays into the vessel's sides for a length of six cubits within and without, in the same way as the Corinthians had altered their prows before engaging the squadron at Naupactus.
The Syracusans thought that they would thus have an advantage over the Athenian vessels, which were not constructed with equal strength, but were slight in the bows, from their being more used to sail round and charge the enemy's side than to meet him prow to prow, and that the battle being in the great harbor, with a great many ships in not much room, was also a fact in their favour.
Charging prow to prow, they would stave in the enemy's bows, by striking with solid and stout beaks against hollow and weak ones;
and secondly, the Athenians for want of room would be unable to use their favorite manoeuvre of breaking the line or of sailing round, as the Syracusans would do their best not to let them do the one, and want of room would prevent their doing the other.
This charging prow to prow which had hitherto been thought want of skill in a helmsman, would be the Syracusans' chief manoeuvre, as being that which they should find most useful, since the Athenians, if repulsed, would not be able to back water in any direction except towards the shore, and that only for a little way, and in the little space in front of their own camp.
The rest of the harbor would be commanded by the Syracusans;
and the Athenians, if hard pressed, by crowding together in a small space and all to the same point, would run foul of one another and fall into disorder, which was, in fact, the thing that did the Athenians most harm in all the sea-fights, they not having, like the Syracusans, the whole harbor to retreat over.
As to their sailing round into the open sea, this would be impossible, with the Syracusans in possession of the way out and in, especially as Plemmyrium would be hostile to them, and the mouth of the harbor was not large.
