Hellenica (2.4.19-2.4.23)

And his saying did not prove false, for when they had taken up their shields, he, as though led on by a kind of fate, leaped forth first of all, fell upon the enemy, and was slain, and he lies buried at the ford of the Cephisus; but the others were victorious, and pursued the enemy as far as the level ground. In this battle fell two of the Thirty, Critias and Hippomachus, one of the Ten who ruled in Piraeus, Charmides, the son of Glaucon, and about seventy of the others. And the victors took possession of their arms, but they did not strip off the tunic[*] of any citizen. When this had been done and while they were giving back the bodies of the dead, many on either side mingled and talked with one another.

And Cleocritus, the herald of the initiated,[*] a man with a very fine voice, obtained silence and said:

On the following day the Thirty, utterly dejected and with but few adherents left, held their session in the council-chamber; and as for the Three Thousand, wherever their several detachments were stationed, everywhere they began to quarrel with one another. For all those who had done any act of especial violence and were therefore fearful, urged strenuously that they ought not to yield to the men in Piraeus; while those who were confident that they had done no wrong, argued in their own minds and set forth to the others that there was no need of their suffering these evils, and they said that they ought not to obey the Thirty or allow them to ruin the state. In the end they voted to depose the Thirty and choose others. And they chose ten, one from[*] each tribe.
