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.
