The Athenians were thus caught in a trap, and their only hope of saving themselves was to force the barrier of the Great Harbour, and escape by sea, or, failing that, to make their way by land to some friendly city. As a last sad confession of defeat, they withdrew the garrison from their walls on Epipolae, and reduced the dimensions of their camp, confining it to a narrow space of the coast, where the fleet lay moored. Every vessel which could be kept afloat was prepared for action, and when the whole force was mustered, out of two great armaments only a hundred and ten were found fit for service. A small body of troops was left to guard the camp, and all the rest, except such as were totally disabled by sickness, were distributed as fighting-men among the ships. For the countrymen of Phormio had now reverted to the primitive conditions of naval warfare, in which the trireme was a mere vehicle for carrying troops, and not, as in the days of that great captain, the chief weapon of offence. Every foot of standing-room on the decks was occupied by a crowd of hoplites, javelin-men, archers, and slingers, and on their prowess the issue of the battle depended. To lay their vessels aboard the enemy with as little delay as possible, and leave the rest to the soldiers, was now the chief object of the Athenian captains; and the better to effect. this, men were stationed on the prows, armed with grappling-irons, to hold the attacking trireme fast, and prevent her from backing away after the first shock of collision.

With hearts full of sad foreboding, the great multitude mustered on the beach, and waited for the word to embark. On a rising ground, fronting the camp, the generals; stood grouped in earnest consultation; then every voice was hushed, as Nicias came forward, and beckoned with his hand, commanding silence. The form of the general was bowed with years, and his face lined with pain and sickness, but in his eye there was an unwonted fire, and his tones rang clear and full, as he reminded his hearers of the great cause for which they were to fight, and the mighty interests which hung in the balance that day. "Men of Athens," he said, "and you, our faithful allies, your lives, your liberty, and the future of all who are dear to you, are in your own hands. If you would ever see home again, you must resolve to conquer fortune, even against her will, like seasoned veterans, inured to the perils and vicissitudes of war. Hitherto we have generally got the better of the enemy on land and we are now going to fight a land battle on the sea. As soon as you come within reach of a Syracusan vessel, fling your grappling-irons, and hold her fast, until not a man is left alive to defend her deck. This will be the task of the soldiers, whom I need not tell to do their duty. And you, seamen of the Athenian fleet, be not dismayed because we have forsaken our former tactics, but trust to the strong arms of the fighting men. Remember, those of you who are not of Attic descent, how long you have enjoyed the high privileges of Athenian citizens, and the honour reflected on you by your connection with Athens.

"My last word shall be spoken to you, fellow-citizens, Athenians born and bred. You know what you have to expect from the Syracusans, if this last struggle should end in defeat. But consider further what will be the fate of your friends at home. Their docks are empty, their walls are stripped of defenders, and if you fail them, Syracuse will unite with their old enemies, and bear them down. Here, where we stand, are the army, the fleet, the city, and the great name of Athens; go, then, and fight as you never fought before, for never yet had soldier such a prize to win, and such a cause to defend."

When Nicias had concluded his stirring appeal, the embarkation of the troops began. As the fatal moment drew nearer and nearer, the anxiety and distress of the Athenian general became unbearable. Feeling that he had not said enough, he hurried to and fro, addressing each captain with an agony of supplication, and imploring him by every sacred name,—his wife, his children, his country, and his country's gods,—to play a man's part, forgetting all thoughts of self. Having exhausted every topic of entreaty, and seen the last man on board, he turned away, still unsatisfied, and addressed himself to the task of drawing up the troops left under his command for the defence of the camp. These were disposed along the shore in as long a line as possible, that they might encourage those fighting on the sea by their presence, and lend prompt help in case of need. Behind them, every point of outlook was held by a throng of anxious spectators,—the sick, the maimed, and the wounded,—every man who had strength to crawl from his bed, and watch that last desperate struggle for liberty and home.

And now the Athenian admirals, Demosthenes, Menander, and Euthydemus, raised the signal, and the great fight began. The foremost ships succeeded in reaching the mouth of the Great Harbour, and began to break through the barrier, when the whole Syracusan fleet closed in upon them on all sides, and forced them back Then the battle became general, and soon the two fleets were scattered over the whole surface of the bay in little groups, and each group engaged in a wild and furious melee. There was no attempt to manoeuvre, but ship encountered ship; as accident brought them together, and advanced to the attack, under a shower of javelins and arrows. Then followed the dull crash of collision, and the fierce rush of the fighting-men, as they endeavoured to board. Here and there could be seen knots of three or four triremes, locked together with shattered hulls and broken oars, while the soldiers on the decks strove for the mastery. Nearly two hundred triremes, and some forty thousand men, were engaged in that tumultuous fight; and the thunder of the oars, the crash of colliding triremes, and the yells of the assailants, raised an uproar so tremendous that it was impossible to hear the voice of command. All order and method was lost, yet still they fought on, the Syracusans with a savage thirst for vengeance, the Athenians with the fury of despair; and for a long time the issue remained doubtful.

All this scene of havoc and carnage was witnessed by the whole population of Syracuse, who thronged the walls, or stood in arms along the shore, and followed every incident with breathless interest. But above all among the Athenians left behind in the camp excitement was strained to the point of anguish. Here the view was more restricted, and each group of spectators had its attention fixed on some one of the many encounters which were raging in different parts of the bay. Some who saw their friends conquering, shouted with joy and triumph; some shrieked in terror, as an Athenian ship went down; and others, when the combat long wavered, rocked their bodies to and fro in an agony of suspense. Thus at the same moment every shifting turn of battle, victory and defeat, panic and rally, flight and pursuit, was mirrored on those pale faces, and echoed in a thousand mingled cries.

But at length these discordant voices were united in one general note of horror, as the whole Athenian fleet, or all that was left of it, was seen making in headlong rout for the upper end of the bay, with the victorious Syracusans pressing hard behind. Then most of those who were watching from the shore were seized with uncontrollable terror, and sought to hide themselves in holes and corners of the camp; while a few, who were more stout-hearted, waded into the water, to save the ships, or rushed to defend the walls on the land side. But for the present the Syracusans were contented with their victory, and after chasing the fugitive triremes as far as their defences, they wheeled and rowed back across the Great Harbour, through floating corpses, and the wrecks of more than seventy vessels. On their arrival at Syracuse they were hailed with such a burst of enthusiasm as had rarely been witnessed in any Greek city. The victory, indeed, had been dearly bought, but it was well worth the cost, and the power of Athens had sustained a blow from which it could never recover. But among all the thronging hosts of Syracuse, who now gave themselves up to revel and rejoicing, there was one man at least who knew that even now the danger was not yet past. Forty thousand Athenian soldiers were still encamped within sight of the walls, and if they were allowed to escape, they might establish themselves in some friendly city, and begin the war again. All this was strongly felt by Hermocrates, and he lost no time in imparting his cares and anxieties to the responsible leaders. The Athenians, he urged, would be almost certain to decamp during the night: let a strong force be sent out at once from Syracuse, to occupy all the roads, and cut off their retreat. The advice was good, but in the present temper of the army it was felt to be impracticable. The whole city had become a scene of riot and wassail, and if the order were given to march, it was but too evident that not a man would obey. Baffled in this direction, the keen-witted Syracusan hit upon another plan, which he at once proceeded to carry into effect.

Hermocrates was not mistaken in his conjecture. The beaten and dispirited Athenians had now but one thought,—to break up their camp with all despatch, and make their escape by land. They had still sixty triremes left, and Demosthenes proposed to make one more attempt to force the entrance of the Great Harbour; but when his suggestion was made known to the crews, they broke into open mutiny, and flatly refused to go on board. The generals were therefore compelled to adopt the only alternative, and it was resolved to set out on that very night. But Fortune had not yet exhausted her malice against the hapless Athenians. The order to strike camp had been issued, and the soldiers were busy preparing for the march, when a party of horsemen rode up to the Athenian outposts, and hailing the sentinels, said that they had a message to Nicias from his friends in Syracuse. "Tell him," said the spokesman of the party, "That he must not attempt to stir to-night, for all the roads are held by strong detachments of the Syracusans. Let him wait until he has organised his forces, for a hasty and disordered flight is sure to end in disaster."

The message, of course, came from Hermocrates, who had contrived this trick to delay the departure of the Athenians, until time had been gained to occupy the passes on their route. That Nicias should have fallen into the snare is not surprising, but it is less easy to explain how Demosthenes and the other generals came to be deceived by so transparent a fraud. Yet such was in fact the case; the insidious hint was accepted as a piece of friendly advice, and the march was postponed. For a whole day and night the Athenians still lingered on the spot, and thus gave ample time for their enemies to draw the net round them, and block every avenue to safety.

On the third day after the battle, the order was given to march. As the great army formed into column, the full horror of their situation came home to every heart. This, then, was the end of those grand dreams of conquest with which they had sailed to Sicily two years before! On the heights of Epipolae their walls and their fort was still standing, a monument of failure and defeat. Each familiar landmark reminded them of some fallen comrade, or some disastrous incident in the siege. If they glanced towards the Great Harbour, they could see the victorious Syracusans towing off the shattered hull of an Athenian trireme, the last sad remnant of two great armaments. If they turned their thoughts towards Athens and home, they found no comfort there; for their beloved city was beset with enemies, and in themselves, beaten and broken as they were, lay her chief hope of salvation. The past was all black with calamity, and the future loomed terrible before them, threatening captivity and death; and the present, in that last hour of parting, was full of such sights and sounds of woe as might have stirred pity even in the breasts of their enemies. Around them, the camp was strewn with the unburied corpses of brothers, comrades and sons, and thousands more were tossing on the waves, or flung up on the shores of the bay. And while the neglect of that sacred duty pressed heavily on their conscience, still more harrowing were the cries of the sick and wounded, who clung round their knees, imploring to be taken with them, and when the army began to move followed with tottering steps, until they sank down exhausted, calling down the curse of heaven on the retreating host. Such was the anguish of that moment, that it seemed as if the whole population of some great city had been driven into exile, and was seeking a new home in a distant soil.
