"We have no excuse, then," said Alcibiades in conclusion, "for breaking our word to the Egestaeans, and drawing back from this enterprise. Both honour and policy are pointing the way to Sicily. An empire like ours is an ever-expanding circle, which lives by growing, and cannot stand still. It is only by getting more, and always more, that we can keep what we have. And let not Nicias succeed in his attempt to set the old against the young, neither let us believe, like him, that the stability of a state consists in stagnation. It is only by a hearty co-operation of all ages and classes that any state can prosper, and a community which finds no outlet for its energies abroad is soon worn out by discord and faction at home. Above all is this true of us Athenians, to whom ceaseless toil and endeavour is the very element in which we live." The advice of Alcibiades, thus tendered in the garb of political wisdom, was of fatal and ruinous tendency, and in direct opposition to the oft-repeated warnings of Pericles. But his speech was exactly suited to the temper of his audience, and most of those who followed him spoke to the same effect, and when the Egestaeans and Leontines renewed their entreaties it became evident that the original motion would be confirmed by a large majority. Nicias, however, resolved to make one more effort, and he came forward to speak again, hoping by a new device to check the torrent of popular enthusiasm. Affecting to regard the matter as settled, he entered into an estimate of the force required for the proposed expedition, prefaced by an alarming picture of the wealth and power of the Sicilian Greeks. To act with effect against such an enemy, they must send, not only an overwhelming naval force, but a numerous body of troops, both cavalry and infantry, and a fleet laden with supplies for many months. They must proceed, in fact, as if they were founding a great city on a hostile soil. On no other condition, added Nicias, would he undertake the command. Nicias had intended, by exaggerating the difficulties of the undertaking, to damp the ardour of the Athenians; but to his utter dismay, these timid counsels were greeted with a great shout of applause. It was supposed that he had changed his opinion, and even the elder men began to think that so prudent a leader, backed by such an armament, could not fail of success. A great wave of excitement swept over the assembly, and the few who still doubted were cowed into silence. When the tumult had subsided, a certain Demostratus, [Footnote: The name is given by Plutarch.] who had spoken strongly in favour of the expedition, addressing Nicias in the name of the assembly, asked him to state plainly what force he required. Thus driven into a corner, Nicias answered, with great reluctance, that the number of triremes must be not less than one hundred, with five thousand heavy-armed infantry, and slingers and bow-men in proportion. This enormous estimate was carried
