Amidst this exaggerated alarm and discord, the general body of hoplites became penetrated with aversion,[87] every day increasing, against the new citadel. At length the hoplites of the tribe in which Aristokratês, the warmest partisan of Theramenês was taxiarch, being on duty and engaged in the prosecution of the building, broke out into absolute mutiny against it, seized the person of Alexiklês, the general in command, and put him under arrest in a neighboring house; while the peripoli, or youthful military police, stationed at Munychia, under Hermon, abetted them in the proceeding.[88] News of this violence was speedily conveyed to the Four Hundred, who were at that moment holding session in the senate-house, Theramenês himself being present. Their wrath and menace were at first vented against him as the instigator of the revolt, a charge against which he could only vindicate himself by volunteering to go among the foremost for the liberation of the prisoner. He forthwith started in haste for the Peiræus, accompanied by one of the generals, his colleague, who was of the same political sentiment as himself. A third among the generals, Aristarchus, one of the fiercest of the oligarchs, followed him, probably from mistrust, together with some of the younger knights, horsemen, or richest class in the state, identified with the cause of the Four Hundred. The oligarchical partisans ran to marshal themselves in arms, alarming exaggerations being rumored, that Alexiklês had been put to death, and that Peiræus was under armed occupation; while at Peiræus the insurgents imagined that the hoplites from the city were in full march to attack them. For a time all was confusion and angry sentiment, which the slightest untoward accident might have inflamed into sanguinary civil carnage. Nor was it appeased except by earnest intreaty and remonstrance from the elder citizens, aided by Thucydidês of Pharsalus, proxenus or public guest of Athens, in his native town, on the ruinous madness of such discord when a foreign enemy was almost at their gates.
