History of the Peloponnesian War

For this reason they pushed forward the construction of their work with posterns and entrances and means of introducing the enemy, being eager to have it finished in time.

Meanwhile the murmurs against them were at first confined to a few persons and went on in secret, until Phrynichus, after his return from the embassy to Lacedaemon, was laid wait for and stabbed in full market by one of the Peripoli, falling down dead before he had gone far from the council chamber. The assassin escaped; but his accomplice, an Argive, was taken and put to the torture by the Four Hundred, without their being able to extract from him the name of his employer, or anything further than that he knew of many men who used to assemble at the house of the commander of the Peripoli and at other houses. Here the matter was allowed to drop. This so emboldened Theramenes and Aristocrates and the rest of their partisans in the Four Hundred and out of doors, that they now resolved to act.

For by this time the ships had sailed round from Las, and anchoring at Epidaurus had overrun Aegina; and Theramenes asserted that, being bound for Euboea, they would never have sailed in to Lacedae and come back to anchor at Epidaurus, unless they had been invited to come to aid in the designs of which he had always accused the government. Further inaction had therefore now become impossible.
