On their arrival, the truce concluded at Pylus was immediately at an end, and the Lacedaemonians asked back their ships, according to agreement. But the Athenians, alleging as grounds of complaint an attack on the fort in contravention of the truce, and other particulars which appear not worth mentioning, refused to return them; laying stress on its having been said, that if there were any violation of it whatever, the truce was at an end. The Lacedaemonians denied it, and charging them with injustice in their conduct respecting the ships, went away, and set themselves to the war.
And now hostilities were carried on at Pylus with the greatest vigour on both sides; the Athenians cruising round the island continually with two ships in opposite directions during the day, while by night they were all moored round it, except on the side of the open sea, whenever there was a wind blowing; (twenty ships too had joined them from Athens to assist in the blockade, so that in all they amounted to seventy; and the Peloponnesians being encamped on the continent, and making attacks on the fort, on the look-out for an opportunity, should any offer, of rescuing their men.
In the mean time the Syracusans and their allies in Sicily, having taken to join the ships on guard at Messana the other squadron which they were preparing, carried on the war from that place.
They were especially urged on to this by the Locrians, out of hatred for the people of Rhegium, whose territory they had themselves also invaded with all their forces.
And they wished to try the result of a sea-fight, seeing that the Athenian ships stationed at Messana were but few; while by the greater part of them, including those that were to come thither, they heard that the island was being blockaded.
For if they gained the advantage by sea, they hoped that by blockading Rhegium both with their land-forces and their ships they would easily reduce it, and then their success would be secured; for as the promontory of Rhegium in Italy, and that of Messana in Sicily, lay close together, the Athenians would not be able to cruise against them, and command the strait.
This strait is formed by the sea between Rhegium and Messana, where Sicily is at the least distance from the continent; and is the Charybdis, so called, through which Ulysses is said to have sailed. And as the sea falls into it through a narrow passage from two great mains, the Tuscan and Sicilian, flowing at the same time with a strong current, it has naturally been considered dangerous.
In this strait then the Syracusans and their allies, with rather more than thirty ships, were compelled to engage, late in the day, about the passage of a boat, and put out to meet sixteen vessels from Athens and eight from Rhegium.
Being defeated by the Athenians, they sailed off with all speed, as they severally happened, to their own camps, the one at Rhegium, the other at Messana, after the loss of one ship, night having overtaken them in the action. After this, the Locrians withdrew from the Rhegian territory;
