Xenophon,
Anabasis — Book 3, Chapter 2
“ It is clear that we must march where we can get provisions. Now, I am told there are some splendid villages not more than two miles and a half distant. I should not be surprised, then, if the enemy were to hang on our heels and dog us as we retire, like cowardly curs which rush out at the passer-by and bite him if they can, but when you turn upon them they run away. Such will be their tactics, I take it. It may be safer, then, to march in a hollow square, so as to place the baggage animals and our mob of sutlers in greater security. ”
