Meanwhile the Thebans heard of it and marched to the rescue, and overtaking the Thracians before they had gone far, recovered the plunder and drove them in panic to the Euripus and the sea, where the vessels which brought them were lying. The greatest slaughter took place while they were embarking, as they did not know how to swim, and those in the vessels on seeing what was going on on on shore moored them out of bowshot: in the rest of the retreat the Thracians made a very respectable defence against the Theban horse, by which they were first attacked, dashing out and closing their ranks according to the tactics of their country, and lost only a few men in that part of the affair. A good number who were after plunder were actually caught in the town and put to death. Altogether the Thracians had two hundred and fifty killed out of thirteen hundred, the Thebans and the rest who came to the rescue about twenty, troopers and heavy infantry, with Scirphondas, one of the Boeotarchs. The Mycalessians lost a large proportion of their population.

While Mycalessus thus experienced a calamity for its extent as lamentable as any that happened in the war, Demosthenes, whom we left sailing to Corcyra, after the building of the fort in Laconia, found a merchantman lying at Phea in Elis, in which the Corinthian heavy infantry were to cross to Sicily. The ship he destroyed, but the men escaped, and subsequently got another in which they pursued their voyage. After this, arriving at Zacynthus and Cephallenia, he took a body of heavy infantry on board, and sending for some of the Messenians from Naupactus, crossed over to the opposite coast of Acarnania, to Alyzia, and to Anactorium which was held by the Athenians. While he was in these parts he was met by Eurymedon returning from Sicily, where he had been sent, as has been mentioned, during the winter, with the money for the army, who told him the news, and also that he had heard, while at sea, that the Syracusans had taken Plemmyrium. Here, also, Conon came to them, the commander at Naupactus, with news that the twenty-five Corinthian ships stationed opposite to him, far from giving over the war, were meditating an engagement; and he therefore begged them to send him some ships, as his own eighteen were not a match for the enemy’s twenty-five. Demosthenes and Eurymedon, accordingly, sent ten of their best sailers with Conon to reinforce the squadron at Naupactus, and meanwhile prepared for the muster of their forces; Eurymedon, who was now the colleague of Demosthenes, and had turned back in consequence of his appointment, sailing to Corcyra to tell them to man fifteen ships and to enlist heavy infantry; while Demosthenes raised slingers and darters from the parts about Acarnania.

Meanwhile the envoys, already mentioned, who had gone from Syracuse to the cities after the capture of Plemmyrium, had succeeded in their mission, and were about to bring the army that they had collected, when Nicias got scent of it, and sent to the Centoripae and Alicyaeans and other of the friendly Sicels, who held the passes, not to let the enemy through, but to combine to prevent their passing, there being no other way by which they could even attempt it, as the Agrigentines would not give them a passage through their country. Agreeably to this request the Sicels laid a triple ambuscade for the Siceliots upon their march, and attacking them suddenly, while off their guard, killed about eight hundred of them and all the envoys, the Corinthian only excepted, by whom fifteen hundred who escaped were conducted to Syracuse.

About the same time the Camarinaeans also came to the assistance of Syracuse with five hundred heavy infantry, three hundred darters, and as many archers, while the Geloans sent crews for five ships, four hundred darters, and two hundred horse. Indeed almost the whole of Sicily, except the Agrigentines, who were neutral, now ceased merely to watch events as it had hitherto done, and actively joined Syracuse against the Athenians.

While the Syracusans after the Sicel disaster put off any immediate attack upon the Athenians, Demosthenes and Eurymedon, whose forces from Corcyra and the continent were now ready, crossed the Ionian Gulf with all their armament to the Iapygian promontory, and starting from thence touched at the Choerades Isles lying off Iapygia, where they took on board a hundred and fifty Iapygian darters of the Messapian tribe, and after renewing an old friendship with Artas the chief, who had furnished them with the darters, arrived at Metapontium in Italy. Here they persuaded their allies the Metapontines to send with them three hundred darters and two galleys, and with this reinforcement coasted on to Thurii, where they found the party hostile to Athens recently expelled by a revolution, and accordingly remained there to muster and review the whole army, to see if any had been left behind, and to prevail upon the Thurians resolutely to join them in their expedition, and in the circumstances in which they found themselves to conclude a defensive and offensive alliance with the Athenians.

About the same time the Peloponnesians in the twenty-five ships stationed opposite to the squadron at Naupactus to protect the passage of the transports to Sicily had got ready for engaging, and manning some additional vessels, so as to be numerically little inferior to the Athenians, anchored off Erineus in Achaia in the Rhypic country. The place off which they lay being in the form of a crescent, the land forces furnished by the Corinthians and their allies on the spot came up and ranged themselves upon the projecting headlands on either side, while the fleet, under the command of Polyanthes, a Corinthian, held the intervening space and blocked up the entrance. The Athenians under Diphilus now sailed out against them with thirty-three ships from Naupactus, and the Corinthians, at first not moving, at length thought they saw their opportunity, raised the signal, and advanced and engaged the Athenians. After an obstinate struggle, the Corinthians lost three ships, and without sinking any altogether, disabled seven of the enemy, which were struck prow to prow and had their foreships stove in by the Corinthian vessels, whose cheeks had been strengthened for this very purpose. After an action of this even character, in which either party could claim the victory (although the Athenians became masters of the wrecks through the wind driving them out to sea, the Corinthians not putting out again to meet them), the two combatants parted. No pursuit took place, and no prisoners were made on either side; the Corinthians and Peloponnesians who were fighting near the shore escaping with ease, and none of the Athenian vessels having been sunk. The Athenians now sailed back to Naupactus, and the Corinthians immediately set up a trophy as victors, because they had disabled a greater number of the enemy’s ships. Moreover they held that they had not been worsted, for the very same reason that their opponent held that he had not been victorious; the Corinthians considering that they were conquerors, if not decidedly conquered, and the Athenians thinking themselves vanquished, because not decidedly victorious. However, when the Peloponnesians sailed off and their land forces had dispersed, the Athenians also set up a trophy as victors in Achaia, about two miles and a quarter from Erineus, the Corinthian station.

This was the termination of the action at Naupactus. To return to Demosthenes and Eurymedon: the Thurians having now got ready to join in the expedition with seven hundred heavy infantry and three hundred darters, the two generals ordered the ships to sail along the coast to the Crotonian territory, and meanwhile held a review of all the land forces upon the river Sybaris, and then led them through the Thurian country. Arrived at the river Hylias, they here received a message from the Crotonians, saying that they would not allow the army to pass through their country; upon which the Athenians descended towards the shore, and bivouacked near the sea and the mouth of the Hylias, where the fleet also met them, and the next day embarked and sailed along the coast touching at all the cities except Locri, until they came to Petra in the Rhegian territory.

Meanwhile the Syracusans hearing of their approach resolved to make a second attempt with their fleet and their other forces on shore, which they had been collecting for this very purpose in order to do something before their arrival. In addition to other improvements suggested by the former sea-fight which they now adopted in the equipment of their navy, they cut down their prows to a smaller compass to make them more solid and made their cheeks stouter, and from these let stays into the vessels’ sides for a length of six cubits within and without, in the same way as the Corinthians had altered their prows before engaging the squadron at Naupactus. The Syracusans thought that they would thus have an advantage over the Athenian vessels, which were not constructed with equal strength, but were slight in the bows, from their being more used to sail round and charge the enemy’s side than to meet him prow to prow, and that the battle being in the great harbour, with a great many ships in not much room, was also a fact in their favour. Charging prow to prow, they would stave in the enemy’s bows, by striking with solid and stout beaks against hollow and weak ones; and secondly, the Athenians for want of room would be unable to use their favourite manoeuvre of breaking the line or of sailing round, as the Syracusans would do their best not to let them do the one, and want of room would prevent their doing the other. This charging prow to prow, which had hitherto been thought want of skill in a helmsman, would be the Syracusans’ chief manoeuvre, as being that which they should find most useful, since the Athenians, if repulsed, would not be able to back water in any direction except towards the shore, and that only for a little way, and in the little space in front of their own camp. The rest of the harbour would be commanded by the Syracusans; and the Athenians, if hard pressed, by crowding together in a small space and all to the same point, would run foul of one another and fall into disorder, which was, in fact, the thing that did the Athenians most harm in all the sea-fights, they not having, like the Syracusans, the whole harbour to retreat over. As to their sailing round into the open sea, this would be impossible, with the Syracusans in possession of the way out and in, especially as Plemmyrium would be hostile to them, and the mouth of the harbour was not large.

With these contrivances to suit their skill and ability, and now more confident after the previous sea-fight, the Syracusans attacked by land and sea at once. The town force Gylippus led out a little the first and brought them up to the wall of the Athenians, where it looked towards the city, while the force from the Olympieum, that is to say, the heavy infantry that were there with the horse and the light troops of the Syracusans, advanced against the wall from the opposite side; the ships of the Syracusans and allies sailing out immediately afterwards. The Athenians at first fancied that they were to be attacked by land only, and it was not without alarm that they saw the fleet suddenly approaching as well; and while some were forming upon the walls and in front of them against the advancing enemy, and some marching out in haste against the numbers of horse and darters coming from the Olympieum and from outside, others manned the ships or rushed down to the beach to oppose the enemy, and when the ships were manned put out with seventy-five sail against about eighty of the Syracusans.

After spending a great part of the day in advancing and retreating and skirmishing with each other, without either being able to gain any advantage worth speaking of, except that the Syracusans sank one or two of the Athenian vessels, they parted, the land force at the same time retiring from the lines. The next day the Syracusans remained quiet, and gave no signs of what they were going to do; but Nicias, seeing that the battle had been a drawn one, and expecting that they would attack again, compelled the captains to refit any of the ships that had suffered, and moored merchant vessels before the stockade which they had driven into the sea in front of their ships, to serve instead of an enclosed harbour, at about two hundred feet from each other, in order that any ship that was hard pressed might be able to retreat in safety and sail out again at leisure. These preparations occupied the Athenians all day until nightfall.
