History of the Peloponnesian War

For at Samos the oligarchy was already made the subject of new measures, and the following events happened at the very time that the Four Hundred were conspiring.

Those of the Samians who had risen up against the aristocratical party, and constituted the commons, turning round again, and being prevailed upon by Pisander on his arrival, and by the Athenians who were in the conspiracy at Samos, both bound themselves by oaths to the number of three hundred, and were prepared to attack the rest, as forming the democratical party.

They also put to death one Hyperbolus, an Athenian, a base fellow, who had been ostracised, not from fear of his influence or rank, but for his villany, and for being a disgrace to the city; acting in the matter in concert with Charminus, one of the generals, and a party of Athenians who were with them, and to whom they had given pledges of faith. They likewise perpetrated other such deeds in conjunction with that party, and had determined to make an attack on the populace.

They, however, having notice of their design, revealed what was going to be done to Leon and Diomedon, two of the generals, (for these submitted to the oligarchy against their will, from being honoured by the people,) and to Thrasybulus and Thrasyllus, the former serving as a trierarch, the latter in the heavy infantry, as well as some others who had always been thought to be most opposed to the conspirators; begging them not to stand still and permit them to be ruined, and Samos to be lost to the Athenians, through whose help alone their empire had held together up to this time.

On hearing this, they went to every one of the soldiers, and exhorted them not to put up with it, and especially the crew of the Paralus, as all on board of that vessel were Athenians and freemen, and had always been most bitter against an oligarchical government, even before there was one established. Leon and Diomedon also left them some ships for their protection, whenever they might themselves sail any where So that when the three hundred made an attack on them, by the aid of all these, and especially of the crew of the Paralus, the popular party of the Samians gained the upper hand.

Of the three hundred they put to death some thirty, and banished three who were the most guilty; while with the rest they entered into an amnesty, and lived together for the future under a democratical government.
