History of the Peloponnesian War

Therefore they went diligently on with the fortification, wherein were wickets and entries and backways for the enemy, and desired to have it finished in time.

And though these things were spoken but amongst a few before and in secret, yet when Phrynichus, after his return from his Lacedaemonian ambassage, was by a certain watchman wounded treacherously in the market place when it was full, as he went from the councilhouse, and not far from it fell instantly dead, and the murtherer gone, and that one of his complices, an Argive, taken by The Four Hundred and put to the torture, would confess no man of those named to him nor anything else saving this, that many men used to assemble at the house of the captain of the watch and at other houses; then at length, because this accident bred no alteration, Theramenes and Aristocrates, and as many other either of The Four Hundred or out of that number as were of the same faction proceeded more boldly to assault the government. For now also the fleet, being come about from Laconia and lying upon the coast of Epidaurus, had made incursions upon Aegina.

And Theramenes thereupon alleged that it was improbable that those galleys holding their course for Euboea would have put in at Aegina and then have gone back again to lie at Epidaurus, unless they had been sent for by such men as he had ever accused of the same; and that therefore there was no reason any longer to sit still.
