The Syracusans wanted also to try their fortune in a sea-fight, seeing that the Athenians had only a few ships at hand, and hearing that the most of their fleet, the ships that were on the way to Sicily, were employed in blockading the island of Sphacteria.

For, in case they won a victory with the fleet, they could then invest Rhegium both by land and by sea and, as they believed, capture it without difficulty; and from that moment their situation would be a strong one, since Rhegium, the extreme point of Italy, and Messene in Sicily are only a short distance apart, and so the Athenians would not be able to keep a fleet there[*](ie. in case Rhegium were taken by the Syracusans.) and command the strait.
