Plutarch, Pelopidas
Bernadotte Perrin, Ed.

11. Now that the fitting time for their undertaking seemed to have come, they sallied forth in two bands; one, under the lead of Pelopidas and Damocleidas, against Leontidas and Hypates, who lived near together; the other against Archias and Philip, under Charon and Melon, who had put on women's apparel over their breastplates, and wore thick garlands of pine and fir which shaded their faces. [2] For this reason, when they stood at the door of the banquet-room, at first the company shouted and clapped their hands, supposing that the women whom they had long been expecting were come. But then, after surveying the banquet and carefully marking each of the reclining guests, the visitors drew their swords, and rushing through the midst of the tables at Archias and Philip, revealed who they were. [3] A few of the guests were persuaded by Phillidas to remain quiet, but the rest, who, with the polemarchs, offered resistance and tried to defend themselves, were dispatched without any trouble, since they were drunk.

Pelopidas and his party, however, were confronted with a harder task; for Leontidas, against whom they were going, was a sober and formidable man, and they found his house closed, since he had already gone to bed. [4] For a long time no one answered their knocking, but at last the attendant heard them and came out and drew back the bolt. As soon as the door yielded and gave way, they rushed in together, overturned the servant, and hastened towards the bed-chamber. But Leontidas, conjecturing what was happening by the very noise and trampling, rose from bed and drew his dagger, [5] but he forgot to overthrow the lamps and make the men fall foul of one another in the darkness. On the contrary, exposed to view by an abundance of light, he went to meet them at the door of his chamber, and struck down the first one that entered, Cephisodorus. When this assailant had fallen, he engaged Pelopidas next; and their conflict was rendered troublesome and difficult by the narrowness of the door and by Cephisodorus, whose body, now dead, lay in their way. [6] But at last Pelopidas prevailed, and after dispatching Leontidas he and his followers went at once to attack Hypates. They broke into his house as they had done into the other, but he promptly perceived their design and fled for refuge to his neighbours. Thither they closely followed him, and caught him, and slew him.
