Phrynichus vs. Alcibiades (from Thuc. 8.47 ff.)

Alcibiades gave this advice to Tissaphernes [not to side with Sparta] ..., not merely because he thought it really the best, but because he was studying means to effect his restoration to his country, well knowing that if he did not destroy it he might one day hope to persuade the Athenians to recall him, and thinking that his best chance of persuading them lay in letting them see that he possessed the favour of Tissaphernes. [2] The event proved him to be right. When the Athenians at Samos found that he had influence with Tissaphernes, principally of their own motion (though partly also through Alcibiades himself sending word to their chief men to tell the best men in the army, that if there were only an oligarchy in the place of the rascally democracy that had banished him, he would be glad to return to his country and to make Tissaphernes their friend), the captains and chief men in the armament at once embraced the idea of subverting the democracy.

48] The design was first mooted in the camp, and afterwards from thence reached the city. Some persons crossed over from Samos and had an interview with Alcibiades, who immediately offered to make first Tissaphernes, and afterwards the king, their friend, if they would give up the democracy, and make it possible for the king to trust them. The higher class, who also suffered most severely from the war, now conceived great hopes of getting the government into their own hands, and of triumphing over the enemy. [2] Upon their return to Samos the emissaries formed their partisans into a club, and openly told the mass of the armament that the king would be their friend, and would provide them with money, if Alcibiades were restored, and the democracy abolished. [3] The multitude, if at first irritated by these intrigues, were nevertheless kept quiet by the advantageous prospect of the pay from the king; and the oligarchical conspirators, after making this communication to the people, now re-examined the proposals of Alcibiades among themselves, with most of their associates. [4] Unlike the rest, who thought them advantageous and trustworthy, Phrynichus, who was still general, by no means approved of the proposals. Alcibiades, he rightly thought, cared no more for an oligarchy than for a democracy, and only sought to change the institutions of his country in order to get himself recalled by his associates; while for themselves their one object should be to avoid civil discord. It was not the king's interest, when the Peloponnesians were now their equals at sea, and in possession of some of the chief cities in his empire, to go out of his way to side with the Athenians whom he did not trust, when he might make friends of the Peloponnesians who had never injured him. [5] And as for the allied states to whom oligarchy was now offered, because the democracy was to be put down at Athens, he well knew that this would not make the rebels come in any the sooner, or confirm the loyal in their allegiance; as the allies would never prefer servitude with an oligarchy or democracy to freedom with the constitution which they actually enjoyed, to whichever type it belonged. [6] Besides, the cities thought that the so-called better classes would prove just as oppressive as the commons, as being those who originated, proposed, and for the most part benefited from the acts of the commons injurious to the confederates. Indeed, if it depended on the better classes, the confederates would be put to death without trial and with violence; while the commons were their refuge and the chastiser of these men. [7] This he positively knew that the cities had learned by experience, and that such was their opinion. The propositions of Alcibiades, and the intrigues now in progress, could therefore never meet with his approval. ...

50]  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, [2] Astyochus, who was still in the neighbourhood of Miletus, to tell him that Alcibiades was ruining their cause by making 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. [3] 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. [4] 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. [5] 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.

51] 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. [2] 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. [3] 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.

[Phrynichus later accused of dereliction and removed from his command; ambushed and killed in 410]
