Xenophon,
Anabasis — Book 3, Chapter 4
“ But when Cheirisophus saw that this ridge was occupied, he summoned Xenophon from the rear, bidding him at the same time to bring up peltasts to the front. That Xenophon hesitated to do, for Tissaphernes and his whole army were coming up and were well within sight. Galloping up to the front himself, he asked: "Why do you summon me?" The other answered him: "The reason is plain; look yonder; this crest which overhangs our descent has been occupied. There is no passing, until we have dislodged these fellows; why have you not brought up the light infantry?" ”
