History of the Peloponnesian War

The Paralus, and in it Chaereas, the son of Archestratus, a man of Athens, one that had been forward in the making of this change, the Samians and the soldiers dispatched presently away to Athens, to advertise them of what was done; for they knew not yet that the government was in the hands of The Four Hundred.

When they arrived, The Four Hundred cast some two or three of these of the Paralus into prison; the rest, after they had taken the galley from them and put them aboard another military galley, they commanded to keep guard about Euboea.

But Chaereas, by some means or other getting presently away, seeing how things went, came back to Samos and related to the army all that the Athenians had done, aggravating it to the utmost, as that they punished every man with stripes to the end that none should contradict the doings of those that bore rule; and that their wives and children at home were abused; and that they had an intention further to take and imprison all that were of kin to any of the army which was not of their faction, to the intent to kill them if they of Samos would not submit to their authority. And many other things he told them, adding lies of his own.

When they heard this, they were ready at first to have fallen upon the chief authors of the oligarchy and upon such of the rest as were partakers of it. Yet afterwards, being hindered by such as came between and advised them not to overthrow the state, the enemy lying so near with their galleys to assault them, they gave it over.

After this, Thrasybulus, the son of Lycus, and Thrasyllus (for these were the principal authors of the change), determining now openly to reduce the state at Samos to a democracy, took oaths of all the soldiers, especially of the oligarchicals, the greatest they could devise, both that they should be subject to the democracy and agree together and also that they should zealously prosecute the war against the Peloponnesians, and withal be enemies to The Four Hundred and not to have to do with them by ambassadors.

The same oath was taken by all the Samians that were of age; and the Athenian soldiers communicated with them their whole affairs, together with whatsoever should succeed of their dangers; for whom and for themselves, they made account there was no refuge of safety; but that if either The Four Hundred or the enemy at Miletus overcame them, they must needs perish.
