Make up your mind to have shoulder-straps early in the campaign. You
cannot afford to miss a single battle. Every opportunity which opens to
you is a city to be taken, and you are to be put in command. See that it
surrenders. No city ever properly besieged evaded final capitulation.
The chances are all in your favor. Remember, when you contemplate your
unambitious comrade, that he is likely to change his tastes as he grows
older. If he cannot give a reasonable degree of encouragement to those
tastes he will then become crabbed and sour. Wherever you see men crusty
and difficult to please, be sure they have had cities to take and
failed to capture them.
