Military strategy is of all the human sciences at once the most ancient and the least developed. It could hardly be otherwise. Its votaries must be men of decision and action rather than of theory. Victory is the payoff, and is regarded as the most telling confirmation of correct judgment. There is no other science where judgments are tested in blood and answered in the servitude of the defeated, where the supreme authority is the leader who has won or can instill confidence that he will win.
Some modicum of theory there always had to be. But like much other military equipment, it had to be light in weight and easily packaged to be carried into the field. Thus, the strategic ideas which have from time to time evolved have no sooner gained acceptance than they have been stripped to their barest essentials and converted into maxims. Because the baggage that was stripped normally contained the justifications, the qualifications, and the instances of historical application or misapplication, the surviving maxim had to be accorded a substitute dignity and authority by treating it as an axiom, or, in latter-day parlance, a “principle.”
