Know you not that the thing is a warfare? one mans duty is to mount guard, another must go out to reconnoitre, a third to battle; all cannot be in one place, nor would it even be expedient. But you, instead of executing your Commanders orders, complain if aught harsher than usual is enjoined; not understanding to what condition you are bringing the army, so far as in you lies. If all were to follow your example, none would dig a trench, none would cast a rampart around the camp, none would keep watch, or expose himself to danger; but all turn out useless for the service of war . Thus it is here also. Every life is a warfare, and that long and various. You must fulfil a soldiers duty, and obey each order at your commanders nod: aye, if it be possible, divine what he would have done; for between that Commander and this, there is no comparison, either in might or in excellence.
