Plutarch De Genio Socratis 28

[28] These words of his, Archidamus, drew tears from many; but he not shedding so much as one, and delivering his son to Pelopidas, went out of the door, saluting and encouraging every one as he went. But you would have been exceedingly surprised at the serene and fearless temper of the boy, with a soul as great as that of Achilles’s son; for he did not change color or seem concerned, but drew out and tried the goodness of Pelopidas’s sword. In the mean time Diotonus, one of Cephisodorus’s friends, came to us with his sword girt and breastplate on; and understanding that Archias had sent for Charon, he chid our delay, and urged us to go and set upon the house presently; for so we should be too quick for them, and take them unprovided. Or, if we did not like that proposal, he said, it was better to go out and fall upon them while they were scattered and in confusion, than to coop ourselves up altogether in one room, and like a hive of bees be taken off by our enemies. Theocritus likewise pressed us to go on, affirming that the sacrifices were lucky, and promised safety and success.
