Phrynichus now saw that there would be a proposal to restore Alcibiades, and that the Athenians would consent to it; and fearing after what he had said against it that Alcibiades, if restored, would revenge himself upon him for his opposition, had recourse to the following expedient. He sent a secret letter to the Lacedaemonian admiral Astyochus, who was still in the neighbourhood of Miletus, to tell him that Alcibiades was ruining their cause by ****** Tissaphernes the friend of the Athenians, and containing an express revelation of the rest of the intrigue, desiring to be excused if he sought to harm his enemy even at the expense of the interests of his country. However, Astyochus, instead of thinking of punishing Alcibiades, who, besides, no longer ventured within his reach as formerly, went up to him and Tissaphernes at Magnesia, communicated to them the letter from Samos, and turned informer, and, if report may be trusted, became the paid creature of Tissaphernes, undertaking to inform him as to this and all other matters; which was also the reason why he did not remonstrate more strongly against the pay not being given in full. Upon this Alcibiades instantly sent to the authorities at Samos a letter against Phrynichus, stating what he had done, and requiring that he should be put to death. Phrynichus distracted, and placed in the utmost peril by the denunciation, sent again to Astyochus, reproaching him with having so ill kept the secret of his previous letter, and saying that he was now prepared to give them an opportunity of destroying the whole Athenian armament at Samos; giving a detailed account of the means which he should employ, Samos being unfortified, and pleading that, being in danger of his life on their account, he could not now be blamed for doing this or anything else to escape being destroyed by his mortal enemies. This also Astyochus revealed to Alcibiades.
Meanwhile Phrynichus having had timely notice that he was playing him false, and that a letter on the subject was on the point of arriving from Alcibiades, himself anticipated the news, and told the army that the enemy, seeing that Samos was unfortified and the fleet not all stationed within the harbour, meant to attack the camp, that he could be certain of this intelligence, and that they must fortify Samos as quickly as possible, and generally look to their defences. It will be remembered that he was general, and had himself authority to carry out these measures. Accordingly they addressed themselves to the work of fortification, and Samos was thus fortified sooner than it would otherwise have been. Not long afterwards came the letter from Alcibiades, saying that the army was betrayed by Phrynichus, and the enemy about to attack it. Alcibiades, however, gained no credit, it being thought that he was in the secret of the enemy's designs, and had tried to fasten them upon Phrynichus, and to make out that he was their accomplice, out of hatred; and consequently far from hurting him he rather bore witness to what he had said by this intelligence.
After this Alcibiades set to work to persuade Tissaphernes to become the friend of the Athenians. Tissaphernes, although afraid of the Peloponnesians because they had more ships in Asia than the Athenians, was yet disposed to be persuaded if he could, especially after his quarrel with the Peloponnesians at Cnidus about the treaty of Therimenes. The quarrel had already taken place, as the Peloponnesians were by this time actually at Rhodes; and in it the original argument of Alcibiades touching the liberation of all the towns by the Lacedaemonians had been verified by the declaration of Lichas that it was impossible to submit to a convention which made the King master of all the states at any former time ruled by himself or by his fathers.
