History of the Peloponnesian War by Thucydides — Book VII, Retreat debated; the eclipse

In the meantime the Athenian generals consulted upon the disaster which had happened, and upon the general weakness of the army. They saw themselves unsuccessful in their enterprises, and the soldiers disgusted with their stay; ^47.2disease being rife among them owing to its being the sickly season of the year, and to the marshy and unhealthy nature of the spot in which they were encamped; and the state of their affairs generally being thought desperate. ^47.3Accordingly, Demosthenes was of opinion that they ought not to stay any longer; but agreeably to his original idea in risking the attempt upon Epipolae, now that this had failed, he gave his vote for going away without further loss of time, while the sea might yet be crossed, and their late reinforcement might give them the superiority at all events on that element. ^47.4He also said that it would be more profitable for the state to carry on the war against those who were building fortifications in Attica, than against the Syracusans whom it was no longer easy to subdue; besides which it was not right to squander large sums of money to no purpose by going on with the siege.

^48.1This was the opinion of Demosthenes. Nicias, without denying the bad state of their affairs, was unwilling to avow their weakness, or to have it reported to the enemy that the Athenians in full council were openly voting for retreat; for in that case they would be much less likely to effect it when they wanted without discovery. ^48.2Moreover, his own particular information still gave him reason to hope that the affairs of the enemy would soon be in a worse state than their own, if the Athenians persevered in the siege; as they would wear out the Syracusans by want of money, especially with the more extensive command of the sea now given them by their present navy. Besides this, there was a party in Syracuse who wished to betray the city to the Athenians, and kept sending him messages and telling him not to raise the siege. ^48.3Accordingly, knowing this and really waiting because he hesitated between the two courses and wished to see his way more clearly, in his public speech on this occasion he refused to lead off the army, saying he was sure the Athenians would never approve of their returning without a vote of theirs. Those who would vote upon their conduct, instead of judging the facts as eye-witnesses like themselves and not from what they might hear from hostile critics, would simply be guided by the calumnies of the first clever speaker; ^48.4while many, indeed most, of the soldiers on the spot, who now so loudly proclaimed the danger of their position, when they reached Athens would proclaim just as loudly the opposite, and would say that their generals had been bribed to betray them and return. For himself, therefore, who knew the Athenian temper, sooner than perish under a dishonorable charge and by an unjust sentence at the hands of the Athenians, he would rather take his chance and die, if die he must, a soldier's death at the hand of the enemy. ^48.5Besides, after all, the Syracusans were in a worse case than themselves. What with paying mercenaries, spending upon fortified posts, and now for a full year maintaining a large navy, they were already at a loss and would soon be at a standstill: they had already spent two thousand talents and incurred heavy debts besides, and could not lose even ever so small a fraction of their present force through not paying it, without ruin to their cause; depending as they did more upon mercenaries than upon soldiers obliged to serve, like their own. ^48.6He therefore said that they ought to stay and carry on the siege, and not depart defeated in point of money, in which they were much superior.

^49.1Nicias spoke positively because he had exact information of the financial distress at Syracuse, and also because of the strength of the Athenian party there which kept sending him messages not to raise the siege; besides which he had more confidence than before in his fleet, and felt sure at least of its success. ^49.2Demosthenes, however, would not hear for a moment of continuing the siege, but said that if they could not lead off the army without a decree from Athens, and if they were obliged to stay on, they ought to remove to Thapsus or Catana; where their land forces would have a wide extent of country to overrun, and could live by plundering the enemy, and would thus do them damage; while the fleet would have the open sea to fight in, that is to say, instead of a narrow space which was all in the enemy's favour, a wide sea-room where their science would be of use, and where they could retreat or advance without being confined or circumscribed either when they put out or put in. ^49.3In any case he was altogether opposed to their staying on where they were, and insisted on removing at once, as quickly and with as little delay as possible; and in this judgment Eurymedon agreed. ^49.4Nicias however still objecting, a certain diffidence and hesitation came over them, with a suspicion that Nicias might have some further information to make him so positive.

^50.1While the Athenians lingered on in this way without moving from where they were, Gylippus and Sicanus now arrived at Syracuse. Sicanus had failed to gain Agrigentum, the party friendly to the Syracusans having been driven out while he was still at Gela; but Gylippus was accompanied not only by a large number of troops raised in Sicily, but by the heavy infantry sent off in the spring from Peloponnese in the merchantmen, who had arrived at Selinus from Libya. ^50.2They had been carried to Libya by a storm, and having obtained two galleys and pilots from the Cyrenians, on their voyage along shore had taken sides with the Euesperitae and had defeated the Libyans who were besieging them, and from thence coasting on to Neapolis, a Carthaginian mart, and the nearest point to Sicily, from which it is only two days' and a night's voyage, there crossed over and came to Selinus. ^50.3Immediately upon their arrival the Syracusans prepared to attack the Athenians again by land and sea at once. The Athenian generals seeing a fresh army come to the aid of the enemy, and that their own circumstances, far from improving, were becoming daily worse, and above all distressed by the sickness of the soldiers, now began to repent of not having removed before; and Nicias no longer offering the same opposition, except by urging that there should be no open voting, they gave orders as secretly as possible for all to be prepared to sail out from the camp at a given signal. ^50.4All was at last ready, and they were on the point of sailing away, when an eclipse of the moon, which was then at the full, took place. Most of the Athenians, deeply impressed by this occurrence, now urged the generals to wait; and Nicias, who was somewhat over-addicted to divination and practices of that kind, refused from that moment even to take the question of departure into consideration, until they had waited the thrice nine days prescribed by the soothsayers.The besiegers were thus condemned to stay in the country;
