His private character was free from any of the stains which polluted that of Alcibiades. On all these points the silence of the comic dramatist is decisive evidence in his favour. He had also the moral courage, not always combined with physical of seeking to do his duty to his country, irrespectively of any odium that he himself might incur, and unhampered by any petty jealousy of those who were associated with him in command. There are few men named in ancient history, of whom posterity would gladly know more, or whom we sympathise with more deeply in the calamities that befel them, than Demosthenes, the son of Alcisthenes, who, in the spring of the year 413 B.C., left Piraeus at the head of the second Athenian expedition against Sicily. His arrival was critically timed; for Gylippus had encouraged the Syracusans to attack the Athenians under Nicias by sea as well as by land, and by an able stratagem of Ariston, one of the admirals of the Corinthian auxiliary squadron, the Syracusans and their confederates had inflicted on the fleet of Nicias the first defeat that the Athenian navy had ever sustained from a numerically inferior foe. Gylippus was preparing to follow up his advantage by fresh attacks on the Athenians on both elements, when the arrival of Demosthenes completely changed the aspect of affairs, and restored the superiority to the invaders. With seventy-three war-galleys in the highest state of efficiency, and brilliantly equipped, with a force of five thousand picked men of the regular infantry of Athens and her allies, and a still larger number of bowmen, javelin-men, and slingers on board, Demosthenes rowed round the great harbour with loud cheers and martial music, as if in defiance of the Syracusans and their confederates. His arrival had indeed changed their newly-born hopes into the deepest consternation. The resources of Athens seemed inexhaustible, and resistance to her hopeless. They had been told that she was reduced to the last extremities, and that her territory was occupied by an enemy; and yet, here they saw her, as if in prodigality of power, sending forth, to make foreign conquests, a second armament, not inferior to that with which Nicias had first landed on the Sicilian shores.
