As soon as Alcibiades heard this news, he returned to Samos, and loosing from hence with his whole fleet, came and offered battle to Lysander. But Lysander, content with the victory he had gained, would not stir. Amongst others in the army who hated Alcibiades, Thrasybulus, the son of Thrason, was his particular enemy, and went purposely to Athens to accuse him, and to exasperate his enemies in the city against him. Addressing the people, he represented that Alcibiades had ruined their affairs and lost their ships by mere self-conceited neglect of his duties, committing the government of the army, in his absence, to men who gained his favour by drinking and scurrilous talking, whilst he wandered up and down at pleasure to raise money, giving himself up to every sort of luxury and excess amongst the courtesans of Abydos and Ionia at a time when the enemy's navy were on the watch close at hand. It was also objected to him, that he had fortified a castle near Bisanthe in Thrace, for a safe retreat for himself, as one that either could not, or would not, live in his own country. The Athenians gave credit to these informations, and showed the resentment and displeasure which they had conceived against him by choosing other generals.
As soon as Alcibiades heard of this, he immediately forsook the army, afraid of what might follow; and, collecting a body of mercenary soldiers, made war upon his own account against those Thracians who called themselves free, and acknowledged no king. By this means he amassed to himself a considerable treasure, and, at the same time, secured the bordering Greeks from the incursions of the barbarians.
Tydeus, Menander, and Adimantus, the new-made generals, were at that time posted at Aegospotami, with all the ships which the Athenians had left. From whence they were used to go out to sea every morning, and offer battle to Lysander, who lay near Lampsacus; and when they had done so, returning back again, lay, all the rest of the day, carelessly and without order, in contempt of the enemy. Alcibiades, who was not far off, did not think so slightly of their danger, nor neglect to let them know it, but, mounting his horse, came to the generals, and represented to them that they had chosen a very inconvenient station, where there was no safe harbour, and where they were distant from any town; so that they were constrained to send for their necessary provisions as far as Sestos. He also pointed out to them their carelessness in suffering the soldiers, when they went ashore, to disperse and wander up and down at their pleasure, while the enemy's fleet, under the command of one general, and strictly obedient to discipline, lay so very near them. He advised them to remove the fleet to Sestos. But the admirals not only disregarded what he said, but Tydeus, with insulting expressions, commanded him to be gone, saying, that now not he, but others, had the command of the forces. Alcibiades, suspecting something of treachery in them, departed, and told his friends, who accompanied him out of the camp, that if the generals had not used him with such insupportable contempt, he would within a few days have forced the Lacedaemonians, however unwilling, either to have fought the Athenians at sea or to have deserted their ships. Some looked upon this as a piece of ostentation only; others said, the thing was probable, for that he might have brought down by land great numbers of the Thracian cavalry and archers, to assault and disorder them in their camp. The event, however, soon made it evident how rightly he had judged of the errors which the Athenians committed. For Lysander fell upon them on a sudden, when they least suspected it, with such fury that Conon alone, with eight galleys, escaped him; all the rest, which were about two hundred, he took and carried away, together with three thousand prisoners, whom he put to death. And within a short time after, he took Athens itself, burnt all the ships which he found there, and demolished their long walls.
