“O friend! I hear some step of hostile feet, Moving this way, or hastening to the fleet; Some spy, perhaps, to lurk beside the main; Or nightly pillager that strips the slain. Yet let him pass, and win a little space; Then rush behind him, and prevent his pace. But if too swift of foot he flies before, Confine his course along the fleet and shore, Betwixt the camp and him our spears employ, And intercept his hoped return to Troy.”
