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 vigor. 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.
