Xenophon,
Anabasis — Book 3, Chapter 3
“ At present the enemy shoot and sling beyond our range, so that our Cretan archers are no match for them; our hand-throwers cannot reach as far; and when we pursue, it is not possible to push the pursuit to any great distance from the main body, and within the short distance no foot-soldier, however fleet of foot, could overtake another foot-soldier who has a bow-shot the start of him. If, then, we are to exclude them from all possibility of injuring us as we march, we must get slingers as soon as possible and cavalry. ”
