Perceiving their intention, the Syracusans began a second counterwork, consisting of a stockade and ditch, which started at the point of junction between the old city-wall and the new, and ran across the low swampy ground as far as the Anapus. Thus the Athenians were confronted by a new obstacle, which had to be removed, before they could make any further progress. Acting with energy and decision, they sent orders to the fleet, which was still lying at Thapsus, to sail round into the Great Harbour; and without waiting for its arrival, before daybreak Lamachus led his troops down the cliff, and advanced against the stockade. His men carried hurdles and planks, to secure their footing in the most treacherous parts of the swamp, and, proceeding thus, in the first light of dawn they came up to the stockade. They found the Syracusans assembled in force to resist them, and an engagement ensued, which speedily ended in favour of the Athenians. The right wing of the Syracusan army fled back into the city, while the left wing retreated towards the suburb of Polichne, hotly pursued by the picked troop [Footnote: P. 203.] of Athenian hoplites, who wished to cut them off before they reached the river. By this rash movement the Athenians came near to forfeiting the advantage which they had gained, and brought upon themselves an irreparable loss. For the Syracusan cavalry turned on their pursuers, and drove them back in disorder upon the Athenian right. The sudden reverse created something like a panic in that part of the line, and Lamachus, who was in command of the left wing, hastened to their relief, and threw himself, with a handful of men, between the Syracusan cavalry and the fugitives. This gallant action turned the tide of battle once more, and gave the Athenians on the right wing time to rally; but Lamachus and his followers, pushing forward too hotly, were attacked by the enemy in a place where their retreat was cut off by a ditch, and slain to a man.

Meanwhile the Syracusans who had fled into the city, observing the temporary defeat of the Athenians, had taken courage again, and they returned to the field, having first sent a detachment to attack the Athenian Circle, where Nicias, who was disabled by sickness, had been left in charge with a small garrison. Thinking to make an easy capture, the party sent on this service ran up the slope of Epipolae, and reached the breastwork of the Circle, which they took and demolished. With the scanty force at his disposal, Nicias had little hope of repelling the attack, so he had recourse to a desperate expedient. He ordered the camp-servants to set fire to a great pile of timber, which was lying, together with a number of siege engines, in front of the wall. They did as he directed, and a great flame arose, which drove back the assailants, and gave warning of his danger to the Athenians in the plain below, where the whole Syracusan army was now in full retreat. Almost at the same moment the Athenian fleet was seen sailing into the Great Harbour, and a strong contingent from the victorious army came swarming up the hill to the rescue. Thereupon the storming party from Syracuse turned and fled back to the city, where they found the streets thronged by their beaten and dispirited comrades.

The result of this battle was to leave the Athenian in undisputed possession of the whole country round Syracuse. Lamachus, indeed, had fallen, and the loss of that daring and active spirit soon made itself severely felt. But for the present the fortunes of Athens were in the ascendant, and everything seemed to promise a speedy triumph. The Syracusans were thoroughly cowed by their defeat, and looked passively on, while a double wall of blockade crept steadily forwards from the southern edge of Epipolae towards the Great Harbour, where the Athenian fleet had now taken up its permanent station. The native Sicels, who had hitherto held back through fear of Syracuse, now joined the Athenians in great numbers. Even the distant Etruscans, the ancient enemies of Syracuse, sent three war-galleys to take part in the sack of the great Dorian city.

Day by day the spirits of the Syracusans sank lower and lower. They now began to feel the actual pressure of a siege. Months had passed since their envoys had sailed for Greece, and there was still no sign of help from Corinth or Sparta. They had lost all hope of saving themselves by their own unaided efforts, and no course seemed left to them but to make the best terms they could with Nicias. Negotiations were accordingly opened with the Athenian general, but after much discussion no definite result was attained. In this hour of weakness and distress, the Syracusans became divided against themselves, and every man suspected his neighbour of treason. Then they turned upon their generals, who, after holding out such high promises, had brought them to this pass, either by mismanagement, or by deliberate treachery. Hermocrates and his colleagues were deposed from their command, and three other generals succeeded to their place.

In the eyes of all those who were watching the struggle, the fate of Syracuse was sealed; she was destined to fall a prey to the devouring ambition of Athens. But at this very moment a little cloud was approaching from the east, which was fraught with disaster and ruin to the besieging army.

VII

Just at the time when the Syracusans were brought to the brink of despair, Gylippus, after so many months' delay, was on his voyage to Sicily. While lying at Leucas, a Corinthian settlement in the Ionian sea, he received the alarming intelligence that Syracuse was already completely blockaded, and the report was confirmed by every vessel that came in from the west. Deceived by these false rumours, he gave up all hope of saving Sicily, but hoping still to forestall the Athenians in Italy, he put out from Leucas with four ships, and steered a straight course for Tarentum. From this city, which was friendly to Sparta and Syracuse, he started on his mission among the Italian Greeks, and putting in at Locri he heard for the first time that the Athenian wall was still unfinished on the northern side of Epipolae, leaving a wide gap, through which a relieving force might enter the town.

Two courses now lay open to Gylippus. He might sail southwards, and make an attempt to run the blockade of Syracuse—or he might land on the northern coast of Sicily, march across the island, and fight his way into the city through the unwalled interval. In either case, the enterprise seemed desperate enough. By a very moderate exertion on the part of Nicias, employing only a fraction of the immense force at his disposal, Gylippus might have been destroyed, before he had time to become dangerous. But Nicias was lulled into a fatal confidence. He had heard of the mission of Gylippus, but made no attempt to oppose his voyage to Italy, regarding him as a mere free-booter, unworthy of serious notice. At last, learning that Gylippus was at Locri, he was induced to send out four triremes against him. They were instructed to take station at Rhegium, and cut off the daring intruder as he passed through the strait. But when they reached Rhegium, the wary Spartan was already beyond their reach. He had decided to approach Syracuse by land, and was now far advanced on his voyage to Himera, the only Greek settlement on the north coast of Sicily. Himera, though an Ionic colony, was attached to the Dorian interest, and her citizens gave a hearty welcome to the Spartan deliverer. Before long, a little army of about three thousand men was assembled at Himera, and ready to follow the fortunes of Gylippus. Seven hundred of these were the sailors and marines from his own vessels, armed as hoplites, and the Himeraeans furnished a thousand infantry, light and heavy-armed, and a hundred cavalry. Owing to the recent death of a powerful chieftain, who had been a strong partisan of Athens, the northern Sicels had now changed sides, and they sent a thousand men to serve under the Spartan leader. Small contingents also arrived, in answer to the call of Gylippus, from Gela and Selinus. With this little force, composed of such motley elements, Gylippus started from Himera, and entered on his march for the relief of Syracuse. The fate of Syracuse was already wavering in the balance. As yet no news of approaching succour had reached the beleaguered city, and the Syracusans had abandoned all hope. To save themselves from a worse calamity, they resolved to surrender, and an assembly was summoned to settle the terms of capitulation. But at this very moment a message came to them by sea, which kindled their courage afresh, and banished these counsels of despair. When Gylippus left Leucas, a Corinthian fleet of some fifteen vessels was preparing to sail from that port for Syracuse. One of the ships, commanded by a certain Gongylus, was delayed in the harbour, and started after the rest. But Gongylus, instead of steering the ordinary course, which would have taken him first to Italy, made a bold dash, straight across the sea, and just when the momentous decision was pending, his ship came to anchor in the Little Harbour. Forthwith the joyful tidings spread like wildfire through the city: Gylippus was coming, armed with full authority from Sparta—Corinth had taken up their cause—Syracuse was saved! All thought of surrender was instantly flung away, and news arriving shortly afterwards that Gylippus was near at hand, the whole Syracusan force marched out to meet him, and escorted him triumphantly into the town.

Thus, without a blow being struck, an immense access of strength had been brought to the besieged, and the grand condition of successful resistance, on which Alcibiades had laid such weight, was fulfilled. A Spartan officer of consummate ability was now in Syracuse, and he had made his way into the city, not alone, not by stealth, but at the head of an army, and before the very eyes of the enemy. Weeks must have elapsed between the departure of Gylippus from Leucas, and his arrival at Syracuse; and during all this time, with one trifling exception, Nicias made no effort to oppose his progress. Prudent men might well have regarded the enterprise of Gylippus as a wild and desperate adventure; and such it must have proved, but for the astounding blindness and apathy of Nicias.

At the time when Gylippus reached Syracuse the Athenian lines of circumvallation were all but completed on the side of the Great Harbour; but a wide interval was still left between the Circle and the northern sea, and it was here that Gylippus had effected an entrance. To keep this space open was a matter of supreme importance, and the scene of action is now shifted again to the northern slope of Epipolae. On the day after his arrival Gylippus succeeded in capturing the Athenian fort at Labdalum, and the command of this position gave increased facilities for the construction of a third counterwall, which was forthwith taken in hand, and carried in the direction of Labdalum, until it crossed the blockading line at its northern end.
