Having thus encouraged one another in their purpose they sent Peisander and one half of1
the envoys back to Athens. They were to carry out the scheme at home, and had directions to set up an oligarchy in the subject-cities at which they touched on their voyage. The other half were despatched different ways other subject-cities.
Diotrephes, who was then at Chios, was sent to assume the command in Chalcidicè and on the coast of Thrace, to which he had been previously appointed. On arriving at Thasos he put down the democracy.
But within about two months of his departure the Thasians began to fortify their city; they did not want to have an aristocracy dependent on Athens when they were daily expecting to obtain their liberty from Lacedaemon.
For there were Thasian exiles who had been driven out by the Athenians dwelling in Peloponnesus, and they, with the assistance of their friends at home, were exerting themselves vigorously to obtain ships and effect the revolt of Thasos. The recent change was exactly what they desired; for the government had been reformed without danger to themselves, and the democracy, who would have opposed them, had been overthrown.
Thus the result in the case of Thasos, and also, as I imagine, of many other states, was the opposite of what the oligarchical conspirators had intended. For the subject-cities, having secured a moderate form of government, and having no fear of being called to account for their proceedings, aimed at absolute freedom; they scorned the2
proffered to them by the Athenians.
