The Spartans might smile when they heard this accomplished traitor professing friendship towards themselves, and zeal for their service; they might be disgusted at the flippant sophistries by which he strove to defend his unexampled villainy. But far different feelings must have been awakened, when he went on to unfold the gigantic scheme of conquest, to which, as he pretended, the invasion of Sicily was no more than a prelude. According to this statement, the Athenians intended, after subjugating the Greeks of Sicily, to turn their arms against the Italian Greeks, and finally to attack Carthage. If all these designs were successful, they would build a great number of new ships, taking their materials from the forests of Italy, raise a vast military force, both of Greeks and barbarians, and then return, backed by the whole power of the West, and draw a ring of war round Peloponnesus. With such resources they would be irresistible, and all Greece must inevitably fall under their sway.
"Such," continued Alcibiades, "is the secret history of the Sicilian expedition, which you have heard from the mouth of him who knows it best. Remember, then, that the issue before you concerns not Syracuse only, but Sparta also: for if Syracuse falls—and fall she must, if left without support—all Sicily will be under the heel of Athens; then will come the turn of Italy, and after that you will soon have the enemy at your own doors. Now learn what you must do, if you would avert all the evils which I have foretold. You must send a fleet to Sicily at once, with hoplites who can row the ships themselves, and serve in the army as soon as they land, and with them a Spartan commander, to organize the fighting men of Sicily, and compel those who are hanging back to do their duty. Such a man will be a host in himself, and will infuse new life and energy into the defence. Further, you must establish a fortified camp at Decelea, a position which commands the whole territory of Attica; for by so doing you will reduce Athens to a state of siege, and compel the whole male population to serve on garrison duty; you will deprive the Athenians of their revenues from the silver-mines at Laurium, and you will put new heart into the cities subject to Athens, and encourage them to withhold their tribute. Let these measures be carried out with promptitude and vigour, and you will soon reap your reward, in the humiliation of Athens, and the honour and gratitude of all Greece."
At these words of Alcibiades the sluggish Spartans took fire, and recognizing the importance of his advice they determined to follow the course which he had indicated. Gylippus, a Spartan of high rank, received orders to proceed at once to Syracuse, and assume the control of the war, and the Corinthians were directed to provide ships for the conveyance of troops. But after this brief display of energy the Spartans relapsed into their wonted torpor. Many months elapsed before Gylippus was able to embark for Sicily, and meanwhile important events had been occurring at the seat of war. We return, therefore, to the head-quarters of Nicias, which had once more been removed from Naxos to Catana.

For the next year and a half [Footnote: Spring 414—autumn 413 B.C.] the scene of our narrative lies almost entirely in the immediate neighbourhood of Syracuse, so that it now becomes necessary to describe in some detail the site of that city, and the character of the adjacent country. Mention has already been made of the island of Ortygia, the site of the original colony, connected with the mainland of Sicily by a bridge or causeway. At the southern extremity of Ortygia there is a narrow strip of land, pointing like a finger towards the rocky peninsula of Plemmyrium; and between these two points lies the entrance to a spacious bay, already alluded to under the name of the Great Harbour. At the western end of the bay there is a long stretch of low, marshy ground, intersected by the little rivers Cyana and Anapus, and infested with fever during the heats of summer. On a rising ground, south of the Anapus, stood the suburb of Polichne, with its great temple, sacred to the Olympian Zeus. A little to the north of Ortygia the coast rises abruptly in a bold line of cliffs, facing eastwards, and forming the base of a triangular plateau, which slopes upwards from the sea, and gradually grows narrower until it ends in a point, called the hill of Euryelus. This plateau, which bore the name of Epipolae, is guarded on all its three sides by rocky precipices, only to be ascended at two or three places. Its eastern end, called Acheadina, from the wild pear-trees which once flourished there, was occupied by a new city, now included with Ortygia in the same wall of defence. Here were situated the famous stone-quarries, which afterwards acquired so tragic an interest from the sufferings of the captive Athenians; and southwards from this district the ground shelves gently to the shores of the Little Harbour, a sheltered inlet at the northern end of Ortygia.
At the opening of spring the operations against Syracuse began in good earnest. The first object of Nicias was to obtain possession of the heights of Epipolae, for since the construction of the new Syracusan wall it had become impossible for him to draw his line of blockade from the side of the Great Harbour. His preparations were already far advanced, when the Syracusan generals resolved to anticipate him, by occupying all the approaches to Epipolae. With this intention they issued an order for a full muster of troops in a meadow by the Anapus, and after a general review and inspection of arms they appointed a picked body of six hundred hoplites to guard the heights of Epipolae, and hold themselves ready for any other pressing service. But the precaution was taken too late. On the night before the review Nicias set sail with his whole army from Catana, and landed at a place called Leon, not more than six or seven furlongs from the northern side of Epipolae. The fleet then took up its station in the sheltered water behind the peninsula of Thapsus, while the land forces, advancing at a run, crossed the level ground, and then, breasting the ascent, gained the summit of Euryelus.
News of their approach presently reached the Syracusans, who were still mustered by the Anapus, and breaking off the review, they marched in haste towards Epipolae, hoping still to dislodge the Athenians from their position. But in their rapid advance over a distance of nearly three miles their ranks became disordered, and their attack was so straggling and ineffectual that they were easily repulsed, and driven back with considerable loss into the town. On the following day Nicias led his troops down the slope, and offered battle before the walls of Syracuse; but the challenge was declined, and the Syracusans remained within their defences, leaving the Athenians in undisputed possession of Epipolae.
After this important success the Athenian generals prepared at once to form the siege of Syracuse. They first constructed a fort at a place called Labdalum, on the northern verge of Epipolae, and near its western extremity, to serve as a safe depositary for their baggage and money. Then, taking up a position near the centre of Epipolae, they built a circular wall, covering a considerable space of ground, and defended on the side towards the city by an outer breastwork, a thousand feet long. This enclosure, which was called the Circle, was intended as a shelter for the men employed on construction of the blockading wall, which started from either side of the Circle, and was to be carried north and south until it reached the sea. The work made rapid progress, and greatly alarmed the Syracusans, who saw themselves in danger of being cut off from all hope of succour on the land side. Dismayed by this prospect, they resolved to make one more effort to drive the Athenians from their position, and marching out in full force, offered battle. Advancing in haste and disorder, they would certainly have suffered a crushing defeat, but for the prudent caution of their generals, who were so much impressed by the superior discipline of the Athenians, that they gave the order to retire, and led their troops back into the city, leaving only a detachment of horse to skirmish with the besiegers. But the Athenians had now an efficient force of cavalry, which had been raised by successive reinforcements to the number of six hundred and fifty men; and these, backed by a small force of infantry, soon drove the horsemen of Syracuse from the field.
The Athenians then completed the building of their Circle, and began to lay the materials for the northern line of wall. By the advice of Hermocrates the Syracusans made no further attempt to attack them in full force, but began to build a counterwall, running out from the city in a direction south of the Athenian Circle, so as to cross the line to be followed by the wall of blockade, and prevent it from reaching the Great Harbour. The work proceeded without interruption, for the Athenians were engaged in their building operations north of the Circle, and did not choose to divide their forces. When it was completed, this counterwork consisted of a solid stone wall, crowned with wooden towers, and defended in front by a palisade. The blockade of Syracuse was thus rendered impossible, as long as the defenders could keep possession of their counterwall. But unfortunately the guards left in charge of the new wail soon began to neglect their duty, and erected tents in the shade, where they passed the hot hours of the afternoon, while some even left their posts, and went off to refresh themselves in the city. The Athenian generals did not fail to take advantage of this negligence. Watching their opportunity, when most of the Syracusan guards were reposing under the shelter of the tents, they sent a chosen troop of some three hundred men to make a sudden assault on the counterwall. Then, having divided the main body of the Athenian army between them, they disposed their forces so as to prevent any rescue from the town. One division was drawn up before the principal gate in the new Syracusan wall, while the other proceeded to a postern-gate, at the point where the counterwall started from the city. The combined movement was completely successful; the three hundred carried the stockade and cross-wall by storm, and compelled the defenders to take refuge within the ramparts of Syracuse. The whole Athenian army then marched up to the counterwall and stockade, which they speedily demolished, carrying off the materials for their own use.
Wishing to prevent any second attempt on the part of the Syracusans to cut them off from the southern slope of Epipolae, the Athenian generals now fortified that part of the cliff which looks towards the Great Harbour. By occupying this point they obtained a new centre, commanding the space between the Circle and the southern edge of the cliff, and placing them in communication with the level valley of the Anapus, across which they had to carry their line of blockade. For the present building operations were suspended on the northern side of the Circle, as they wished first of all to complete the investment of Syracuse towards the south.
