XIX. At this crisis there arrived at Syracuse Gongylus, a Corinthian, in one trireme. All crowded round him, to hear what news he brought. He informed them that Gylippus would soon come to their aid by land, and that other triremes besides his own were on their way by sea. This intelligence was scarcely believed, until it was confirmed by a message from Gylippus himself, bidding them march out and meet him. They now took courage and prepared for battle. Gylippus marched into the town, and at once led the Syracusans out to attack the Athenians. When Nikias had likewise brought his army out of their camp, Gylippus halted his men, and sent a herald to offer them an armistice for five days, on condition that they would collect their effects and withdraw from Sicily. Nikias disdained to answer this insulting message; but some of his soldiers jeeringly enquired whether the presence of one Spartan cloak and staff had all at once made the Syracusans so strong that they could despise the Athenians, who used to keep three hundred such men, stronger than Gylippus and with longer hair, locked up in prison, and feared them so little that they delivered them up to the Lacedæmonians again. Timæus says that the Sicilian Greeks despised Gylippus for his avaricious and contemptible character, and that when they first saw him, they ridiculed his long hair and Spartan cloak. Afterwards, however, he tells us that as soon as Gylippus appeared they flocked round him as small birds flock round an owl, and were eager to take service under him. This indeed is the more probable story; for they rallied round him, regarding his cloak and staff to be the symbols of the authority of Sparta. And not only Thucydides, but Philistus, a Syracusan citizen by birth, who was an eye-witness of the whole campaign, tells us that nothing could have been done without Gylippus. In the first battle after his arrival, the Athenians were victorious, and slew some few Syracusans, amongst whom was the Corinthian Gongylus, but on the following day Gylippus displayed the qualities of a true general. He used the same arms, horses, and ground as before, but he dealt with them so differently that he defeated the Athenians. Checking the Syracusans, who wished to chase them back to their camp, he ordered them to use the stones and timber which had been collected by the Athenians, to build a counter-wall, reaching beyond the line of circumvallation, so that the Athenians could no longer hope to surround the city. And now the Syracusans, taking fresh courage, began to man their ships of war, and to cut off the stragglers with their cavalry. Gylippus personally visited many of the Greek cities in Sicily, all of whom eagerly promised their aid, and furnished him with troops; so that Nikias, perceiving that he was losing ground, relapsed into his former desponding condition, and wrote a despatch to Athens, bidding the people either send out another armament, or let the one now in Sicily return to Athens, and especially beseeching them to relieve him from his command, for which he was incapacitated by disease.
XX. The Athenians had long before proposed to send out a reinforcement to the army in Sicily, but as all had gone on prosperously, the enemies of Nikias had contrived to put it off. Now, however, they were eager to send him assistance. It was arranged that Demosthenes should employ himself actively in getting ready a large force, to go to reinforce Nikias in the early spring, while Eurymedon, although it was winter, started immediately with a supply of money, and with a decree naming Euthydemus and Menander, officers already serving in his army, to be joint commanders along with him. Meanwhile, Nikias was suddenly attacked by the Syracusans both by sea and land. His ships were at first thrown into confusion, but rallied and sank many of the enemy, or forced them to run on shore; but on land Gylippus managed at the same time to surprise the fort of Plemmyrium, where there was a magazine of naval stores and war material of all kinds. A considerable number of the garrison, also, were either slain or taken prisoners; but the most serious result was the stoppage of Nikias's supplies, which heretofore had been easily and quickly brought through the Great Harbour, while it remained in the hands of the Athenians, but which now could not reach his camp by sea without a convoy and a battle.[2] Moreover, the Syracusan fleet had not been defeated by any superiority of force of the Athenians, but by the disorder into which it had been thrown by pursuing the enemy. They therefore determined to renew the conflict with better success.
Nikias, on his part, was unwilling to fight a second time, thinking it was folly to fight with a diminished and disheartened force when he knew that Demosthenes was hurrying to his aid with a large and unbroken armament. However, Menander and Euthydemus, the newly-elected generals, were eager to distinguish themselves by performing some brilliant action before the arrival of Demosthenes, and to eclipse the fame of Nikias himself. The pretext they used was the glory of Athens, which they said would be dishonoured for ever if they should now appear afraid to accept the Syracusans' offer of battle. The battle was fought: and the Athenian left wing, we are told by Thucydides, was utterly defeated by the skilful tactics of the Corinthian steersman Aristion. Many Athenians perished, and Nikias was greatly disheartened, for he had now proved unfortunate both when sole commander and when acting with colleagues.
XXI. Matters were in this posture when Demosthenes was descried in the offing, approaching with a splendid armament which struck terror into the hearts of the enemy. His fleet consisted of seventy-three ships, on board of which were five thousand heavy-armed troops, and three thousand javelin men, archers, and slingers. The glittering arms of the troops, the flaunting banners of the ships of war, and the music of the flutes to which the rowers kept time with their oars, made a gallant display, which delighted the Athenians as much as it depressed the Syracusans. These latter, indeed, were struck with dismay, and thought that their last victory had been won in vain, and that they were labouring to no purpose against a foe whose ranks were continually reinforced.
Nikias was not long allowed to feast his eyes on this welcome spectacle undisturbed. Demosthenes, as soon as he landed, insisted on the necessity of instantly attacking Syracuse, and putting an end to the siege, either by capturing the place, or by returning at once to Athens in case of failure. Against this Nikias, who was alarmed at the idea of such vigorous action, urged that it would be unwise to run such a risk. Delay, he argued, favoured the besiegers more than the besieged, as their resources must soon fail, in which case their allies would desert them and they would again be brought to the necessity of capitulating. Nikias adopted this view because of what he heard from his secret correspondents within the city, who urged him to continue the siege, telling him that already the Syracusans began to feel the war too great a burden for them to support, and that Gylippus was very unpopular among them, so that in a short time they would utterly refuse to hold out any longer, and would come to terms with the Athenians. Nikias could only hint at these secret sources of information, and so his counsels were thought by his colleagues to be mere cowardice. They declared loudly that the original mistake was about to be repeated, and the first terror-stricken impression of the armament frittered away, until familiarity with the sight of it had bred contempt in the breasts of their enemies. They therefore eagerly seconded the proposal of Demosthenes, and forced Nikias, though sorely against his will, to yield to their representations. Accordingly, Demosthenes with the land force assaulted the outlying fort on the high ground of Epipolæ by night, and took it by surprise, killing part of its garrison and putting the remainder to flight. He did not halt there, but followed up his success by marching further on towards the city, until he was met by some Bœotian heavy-armed troops, who had been the first to rally, and now in a compact mass met the Athenians with their spears levelled, and with loud shouts forced them to give way with severe loss. The whole Athenian army was by this thrown into confusion and panic, as the fugitives broke the formation of those troops who were still marching to the front, so that in some cases they actually fought with one another, each believing the others to be enemies. Thus the Athenians fell into sad disorder and ruin; for they were unable to distinguish friends from foes in the uncertain light, as the moon, now nearly setting, glanced upon spear-points and armour without showing them clearly enough to enable men to see with whom they had to deal. The moon was behind the backs of the Athenians: and this circumstance was greatly against them, for it made it hard for them to see the numbers of their own friends, but shone plainly on the glittering shields of their antagonists, making them look taller and more terrible than they were. Finally, attacked as they were on every side, they gave way and fled. Some were slain by the enemy, some by their own countrymen, and some were dashed to pieces by falling down the precipices; while the rest, as they straggled about the country, were cut off by the Syracusan cavalry. Two thousand men perished, and of the survivors few brought back their arms.
