Leaving out, for the sake of shortness, the rest of his strategical thoughts, I hasten to conclude this sketch with a glance at Clausewitz's admirable summary[59] of strategic principles:-- "_The first and most important maxim which we can set before ourselves is to employ_ ALL _the forces which we can make available with the_ UTMOST ENERGY. Even if the result is tolerably certain in itself, it is extremely unwise not to make it _perfectly certain_. "_The second principle is to concentrate our forces as much as possible at the point where the_ DECISIVE _blow is to be struck. The success at that point will compensate for all defeats at secondary points._ "_The third principle is not to lose time. Rapidity and surprise are the most powerful elements of victory._ "_Lastly, the fourth principle is to_ FOLLOW UP THE SUCCESS _we gain with the_ UTMOST ENERGY. _The pursuit of the enemy when defeated is the only means of gathering up the fruits of victory._ "The first of these principles is the foundation of all the others. _If we have followed the first principle, we can venture any length with regard to the three others without risking our all._ It gives the means of _continually creating new forces behind us_, and with new forces every disaster may be repaired. _In this, and not in going forward with timid steps, lies that prudence which may be called wise._" These great principles are everything in war, and "due regard being paid to these principles, the form (_i.e._ the geometrical element) in which the operations are carried on is in the end of little consequence." "Therefore I am perfectly convinced that whoever calls forth all his powers to appear _incessantly with new masses_, whoever adopts _every imaginable means of preparation_, whoever _concentrates his force at the decisive point, whoever thus armed pursues a great object with resolution and energy_, has done all that can be done in a general way for the strategical conduct of the war, and that, unless he is altogether unfortunate in battle, will undoubtedly be victorious in the same measure that his adversary has fallen short of this exertion and energy." REFLECTIONS When we have got these great simple leading principles of strategy firmly into our heads, the next question is how to make use of our knowledge. For principles are no use unless we apply them. On consideration it appears that there are three ways in which we can all apply these principles with advantage.
