Plutarch De Genio Socratis 34

[34] Our affairs being in this condition, understanding that Epaminondas, Gorgidas, and their friends were drawing into a body about Minerva’s temple, I went to them. Many honest worthy citizens at first joined, and their number continually increased. When I had informed them in the particulars of what was done, and desired them to march into the market-place to assist their friends, they proclaimed liberty; and the multitude were furnished with arms out of the piazzas, that were stuffed with spoil, and the neighboring armorers’ shops. Then Hipposthenides with his friends and servants appeared, having by chance joined the trumpeters that were coming to Thebes, against the feast of Hercules. Straight some gave the alarm in the market-place, others in other parts of the city, distracting their enemies on all sides, as if the whole city was in arms. Some, lighting smoky fire, concealed themselves in the cloud and fled to the castle, drawing to them the select band which used to keep guard about the castle all night. The garrison of the castle, when these poured in among them scattered and in disorder, though they saw us all in confusion, and knew we had no standing compact body, yet would not venture to make a descent, though they were above five thousand strong. They were really afraid, but pretended they dared not move without Lysanoridas’s orders, who, contrary to his usual custom, was absent from the castle that day. For which neglect, the Spartans (as I was told), having got Lysanoridas into their hands, fined him heavily; and having taken Hermippidas and Arcesus at Corinth, they put them both to death without delay. And surrendering the castle to us upon articles, they marched out with their garrison.
