History of the Peloponnesian War

Accordingly, 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.

He 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.

This 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.

Moreover, 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.
