After continuing their attacks during that day and most of the next, the Peloponnesians desisted, and the day after sent some of their ships to Asine for timber to make engines, hoping to take by their aid, in spite of its height, the wall opposite the harbour, where the landing was easiest. At this moment the Athenian fleet from Zacynthus arrived, now numbering fifty sail, having been reinforced by some of the ships on guard at Naupactus and by four Chian vessels. Seeing the coast and the island both crowded with heavy infantry, and the hostile ships in harbour showing no signs of sailing out, at a loss where to anchor, they sailed for the moment to the desert island of Prote, not far off, where they passed the night. The next day they got under way in readiness to engage in the open sea if the enemy chose to put out to meet them, being determined in the event of his not doing so to sail in and attack him. The Lacedaemonians did not put out to sea, and having omitted to close the inlets as they had intended, remained quiet on shore, engaged in manning their ships and getting ready, in the case of any one sailing in, to fight in the harbour, which is a fairly large one.

Perceiving this, the Athenians advanced against them by each inlet, and falling on the enemy’s fleet, most of which was by this time afloat and in line, at once put it to flight, and giving chase as far as the short distance allowed, disabled a good many vessels and took five, one with its crew on board; dashing in at the rest that had taken refuge on shore, and battering some that were still being manned, before they could put out, and lashing on to their own ships and towing off empty others whose crews had fled. At this sight the Lacedaemonians, maddened by a disaster which cut off their men on the island, rushed to the rescue, and going into the sea with their heavy armour, laid hold of the ships and tried to drag them back, each man thinking that success depended on his individual exertions. Great was the melee, and quite in contradiction to the naval tactics usual to the two combatants; the Lacedaemonians in their excitement and dismay being actually engaged in a sea-fight on land, while the victorious Athenians, in their eagerness to push their success as far as possible, were carrying on a land-fight from their ships. After great exertions and numerous wounds on both sides they separated, the Lacedaemonians saving their empty ships, except those first taken; and both parties returning to their camp, the Athenians set up a trophy, gave back the dead, secured the wrecks, and at once began to cruise round and jealously watch the island, with its intercepted garrison, while the Peloponnesians on the mainland, whose contingents had now all come up, stayed where they were before Pylos.

When the news of what had happened at Pylos reached Sparta, the disaster was thought so serious that the Lacedaemonians resolved that the authorities should go down to the camp, and decide on the spot what was best to be done. There, seeing that it was impossible to help their men, and not wishing to risk their being reduced by hunger or overpowered by numbers, they determined, with the consent of the Athenian generals, to conclude an armistice at Pylos and send envoys to Athens to obtain a convention, and to endeavour to get back their men as quickly as possible.

The generals accepting their offers, an armistice was concluded upon the terms following:

That the Lacedaemonians should bring to Pylos and deliver up to the Athenians the ships that had fought in the late engagement, and all in Laconia that were vessels of war, and should make no attack on the fortification either by land or by sea.

That the Athenians should allow the Lacedaemonians on the mainland to send to the men in the island a certain fixed quantity of corn ready kneaded, that is to say, two quarts of barley meal, one pint of wine, and a piece of meat for each man, and half the same quantity for a servant.

That this allowance should be sent in under the eyes of the Athenians, and that no boat should sail to the island except openly.

That the Athenians should continue to the island same as before, without however landing upon it, and should refrain from attacking the Peloponnesian troops either by land or by sea.

That if either party should infringe any of these terms in the slightest particular, the armistice should be at once void.

That the armistice should hold good until the return of the Lacedaemonian envoys from Athens—the Athenians sending them thither in a galley and bringing them back again—and upon the arrival of the envoys should be at an end, and the ships be restored by the Athenians in the same state as they received them.
