Their arrival at once put an end to the armistice at Pylos, and the Lacedaemonians asked back their ships according to the convention. The Athenians, however, alleged an attack on the fort in contravention of the truce, and other grievances seemingly not worth mentioning, and refused to give them back, insisting upon the clause by which the slightest infringement made the armistice void. The Lacedaemonians, after denying the contravention and protesting against their bad faith in the matter of the ships, went away and earnestly addressed themselves to the war. Hostilities were now carried on at Pylos upon both sides with vigour. The Athenians cruised round the island all day with two ships going different ways; and by night, except on the seaward side in windy weather, anchored round it with their whole fleet, which, having been reinforced by twenty ships from Athens come to aid in the blockade, now numbered seventy sail; while the Peloponnesians remained encamped on the continent, making attacks on the fort, and on the look-out for any opportunity which might offer itself for the deliverance of their men. Meanwhile the Syracusans and their allies in Sicily had brought up to the squadron guarding Messina the reinforcement which we left them preparing, and carried on the war from thence, incited chiefly by the Locrians from hatred of the Rhegians, whose territory they had invaded with all their forces. The Syracusans also wished to try their fortune at sea, seeing that the Athenians had only a few ships actually at Rhegium, and hearing that the main fleet destined to join them was engaged in blockading the island. A naval victory, they thought, would enable them to blockade Rhegium by sea and land, and easily to reduce it; a success which would at once place their affairs upon a solid basis, the promontory of Rhegium in Italy and Messina in Sicily being so near each other that it would be impossible for the Athenians to cruise against them and command the strait. The strait in question consists of the sea between Rhegium and Messina, at the point where Sicily approaches nearest to the continent, and is the Charybdis through which the story makes Ulysses sail; and the narrowness of the passage and the strength of the current that pours in from the vast Tyrrhenian and Sicilian mains, have rightly given it a bad reputation.
