Phrynichus was exceedingly disturbed, since he was in the very greatest danger on account of the information he had given; he accordingly wrote again to Astyochus, reproaching him because his former information had not been concealed, as in honour it should have been, and adding that now he was ready to furnish the Lacedaemonians the opportunity to destroy the whole Athenian army at Samos, stating in detail how he could do this, since Samos was without walls; it was not culpable in himself, he concluded, now that he was in danger of his life through their actions, to do this or anything else rather than perish himself at the hands of his bitterest enemies. But Astyochus gave information of this also to Alcibiades.
And when Phrynichus learned betimes that Astyochus was working to injure him and that a letter from Alcibiades about these matters had all but come, he anticipated it by himself informing the army that the enemy intended, seeing that Samos had no walls and that not all the ships were anchored inside the harbour, to attack the camp; he said that he had certain information of this, and that they ought to fortify Samos as quickly as possible and keep a watch upon everything. Now he was general, and was within his powers in acting thus on his own authority.
