When the day came for the assembly in the theatre, and they were upon the point of assembling, news arrived that the forty-two ships under Agesandridas were sailing from Megara along the coast of Salamis. The people to a man now thought that it was just what Theramenes and his party had so often said, that the ships were sailing to the fortification, and concluded that they had done well to demolish it. But though it may possibly have been by appointment that Agesandridas hovered about Epidaurus and the neighbourhood, he would also naturally be kept there by the hope of an opportunity arising out of the troubles in the town. In any case the Athenians, on receipt of the news immediately ran down in mass to Piraeus, seeing themselves threatened by the enemy with a worse war than their war among themselves, not at a distance, but close to the harbour of Athens. Some went on board the ships already afloat, while others launched fresh vessels, or ran to defend the walls and the mouth of the harbour.
Meanwhile the Peloponnesian vessels sailed by, and rounding Sunium anchored between Thoricus and Prasiae, and afterwards arrived at Oropus. The Athenians, with revolution in the city, and unwilling to lose a moment in going to the relief of their most important possession (for Euboea was everything to them now that they were shut out from Attica), were compelled to put to sea in haste and with untrained crews, and sent Thymochares with some vessels to Eretria. These upon their arrival, with the ships already in Euboea, made up a total of thirty-six vessels, and were immediately forced to engage. For Agesandridas, after his crews had dined, put out from Oropus, which is about seven miles from Eretria by sea; and the Athenians, seeing him sailing up, immediately began to man their vessels. The sailors, however, instead of being by their ships, as they supposed, were gone away to purchase provisions for their dinner in the houses in the outskirts of the town; the Eretrians having so arranged that there should be nothing on sale in the marketplace, in order that the Athenians might be a long time in manning their ships, and, the enemy's attack taking them by surprise, might be compelled to put to sea just as they were. A signal also was raised in Eretria to give them notice in Oropus when to put to sea. The Athenians, forced to put out so poorly prepared, engaged off the harbour of Eretria, and after holding their own for some little while notwithstanding, were at length put to flight and chased to the shore. Such of their number as took refuge in Eretria, which they presumed to be friendly to them, found their fate in that city, being butchered by the inhabitants; while those who fled to the Athenian fort in the Eretrian territory, and the vessels which got to Chalcis, were saved. The Peloponnesians, after taking twenty-two Athenian ships, and killing or ****** prisoners of the crews, set up a trophy, and not long afterwards effected the revolt of the whole of Euboea (except Oreus, which was held by the Athenians themselves), and made a general settlement of the affairs of the island.
When the news of what had happened in Euboea reached Athens, a panic ensued such as they had never before known. Neither the disaster in Sicily, great as it seemed at the time, nor any other had ever so much alarmed them. The camp at Samos was in revolt; they had no more ships or men to man them; they were at discord among themselves and might at any moment come to blows; and a disaster of this magnitude coming on the top of all, by which they lost their fleet, and worst of all Euboea, which was of more value to them than Attica, could not occur without throwing them into the deepest despondency. Meanwhile their greatest and most immediate trouble was the possibility that the enemy, emboldened by his victory, might make straight for them and sail against Piraeus, which they had no longer ships to defend; and every moment they expected him to arrive. This, with a little more courage, he might easily have done, in which case he would either have increased the dissensions of the city by his presence, or, if he had stayed to besiege it, have compelled the fleet from Ionia, although the enemy of the oligarchy, to come to the rescue of their country and of their relatives, and in the meantime would have become master of the Hellespont, Ionia, the islands, and of everything as far as Euboea, or, to speak roundly, of the whole Athenian empire. But here, as on so many other occasions, the Lacedaemonians proved the most convenient people in the world for the Athenians to be at war with. The wide difference between the two characters, the slowness and want of energy of the Lacedaemonians as contrasted with the dash and enterprise of their opponents, proved of the greatest service, especially to a maritime empire like Athens. Indeed this was shown by the Syracusans, who were most like the Athenians in character, and also most successful in combating them.
Nevertheless, upon receipt of the news, the Athenians manned twenty ships and called immediately a first assembly in the Pnyx, where they had been used to meet formerly, and deposed the Four Hundred and voted to hand over the government to the Five Thousand, of which body all who furnished a suit of armour were to be members, decreeing also that no one should receive pay for the discharge of any office, or if he did should be held accursed. Many other assemblies were held afterwards, in which law-makers were elected and all other measures taken to form a constitution. It was during the first period of this constitution that the Athenians appear to have enjoyed the best government that they ever did, at least in my time.
For the fusion of the high and the low was effected with judgment, and this was what first enabled the state to raise up her head after her manifold disasters. They also voted for the recall of Alcibiades and of other exiles, and sent to him and to the camp at Samos, and urged them to devote themselves vigorously to the war.
