By this comes to light for the inexperienced eye one of those things which put fetters in the dark, as it were, on the action of the mind, and wear out in secret the powers of the soul.
Although here the question is strictly only respecting the extreme effort required by a Commander from his Army, by a leader from his followers, therefore of the spirit to demand it and of the art of getting it, still the personal physical exertion of Generals and of the Chief Commander must not be overlooked. Having brought the analysis of War conscientiously up to this point, we could not but take account also of the weight of this small remaining residue.
We have spoken here of bodily effort, chiefly because, like danger, it belongs to the fundamental causes of friction, and because its indefinite quantity makes it like an elastic body, the friction of which is well known to be difficult to calculate.
To check the abuse of these considerations, of such a survey of things which aggravate the difficulties of War, nature has given our judgment a guide in our sensibilities, just as an individual cannot with advantage refer to his personal deficiencies if he is insulted and ill-treated, but may well do so if he has successfully repelled the affront, or has fully revenged it, so no Commander or Army will lessen the impression of a disgraceful defeat by depicting the danger, the distress, the exertions, things which would immensely enhance the glory of a victory. Thus our feeling, which after all is only a higher kind of judgment, forbids us to do what seems an act of justice to which our judgment would be inclined.
