But Pelopidas and his companions, dressing themselves like countrymen, divided, and, whilst it was yet day, entered at different quarters of the city. It was, besides, a windy day, and now it just began to snow, which contributed much to their concealment, because most people were gone indoors to avoid the weather. Those, however, that were concerned in the design received them as they came, and conducted them to Charon's house, where the exiles and others made up forty-eight in number. The tyrant's affairs stood thus: the secretary, Phillidas, as I have already observed, was an accomplice in and privy to all the contrivance of the exiles, and he a while before had invited Archias, with others, to an entertainment on that day, to drink freely, and meet some women of the town, on purpose that when they were drunk, and given up to their pleasures, he might deliver them over to the conspirators. But before Archias was thoroughly heated notice was given him that the exiles were privately in the town; a true report indeed, but obscure, and not well confirmed: nevertheless, though Phillidas endeavoured to divert the discourse, Archias sent one of his guards to Charon, and commanded him to attend immediately. It was evening, and Pelopidas and his friends with him in the house were putting themselves into a fit posture for action, having their breastplates on already, and their swords girt: but at the sudden knocking at the door, one stepping forth to inquire the matter, and learning from the officer that Charon was sent for by the polemarch, returned in great confusion and acquainted those within; and immediately conjectured that the whole plot was discovered, and they should be cut in pieces, before so much as achieving any action to do credit to their bravery: yet all agreed that Charon should obey and attend the polemarch to prevent suspicion. Charon was, indeed, a man of courage and resolution in all dangers, yet in this case he was extremely concerned, lest any should suspect that he was the traitor and the death of so many brave citizens he laid on him. And, therefore, when he was ready to depart, he brought his son out of the women's apartment, a little boy as yet, but one of the best looking and strongest of all those of his age, and delivered him to Pelopidas with these words: "If you find me a traitor, treat the boy as an enemy without any mercy." The concern which Charon showed drew tears from many; but all protested vehemently against his supposing any one of them so mean-spirited and base, at the appearance of approaching danger, as to suspect or blame him; and therefore desired him not to involve his son, but to set him out of harm's way: that so he, perhaps escaping the tyrant's power, might live to revenge the city and his friends. Charon, however, refused to remove him, and asked, "What life, what safety could be more honourable, than to die bravely with his father and such generous companions?" Thus, imploring the protection of the gods, and saluting and encouraging them all, he departed, considering with himself, and composing his voice and countenance, that he might look as little like as possible to what in fact he really was.
When he was come to the door, Archias with Phillidas came out to him, and said, "I have heard, Charon, that there are some men just come, and lurking in the town, and that some of the citizens are resorting to them." Charon was at first disturbed, but asking, "Who are they? and who conceals them?" and finding Archias did not thoroughly understand the matter, he concluded that none of those privy to the design had given this information, and replied, "Do not disturb yourselves for an empty rumour: I will look into it, however, for no report in such a case is to be neglected."Phillidas, who stood by, commended him, and leading back Archias, got him deep in drink, still prolonging the entertainment with the hopes of the women's company at last. But when Charon returned, and found the men prepared, not as if they hoped for safety and success, but to die bravely and with the slaughter of their enemies, he told Pelopidas and his friends the truth, but pretended to others in the house that Archias talked to him about something else, inventing a story for the occasion. This storm was just blowing over, when fortune brought another; for a messenger came with a letter from one Archias, the Hierophant at Athens, to his namesake Archias, who was his friend and guest. This did not merely contain a vague conjectural suspicion, but, as it appeared afterwards, disclosed every particular of the design. The messenger being brought in to Archias, who was now pretty well drunk, and delivering the letter, said to him, "The writer of this desired it might be read at once; it is on urgent business." Archias, with a smile, replied, "Urgent business tomorrow," and so receiving the letter, he put it under his pillow, and returned to what he had been speaking of with Phillidas, and these words of his are a proverb to this day amongst the Greeks.
