Clausewitz, On War
A prince or general who knows exactly how to organise his war according to his object and means, who does neither too little nor too much, gives by that the greatest proof of his genius.
But the effects of this talent are exhibited not so much by the invention of new modes of action, which might strike the eye immediately, as in the successful final result of the whole.
It is the exact fulfilment of silent suppositions, it is the noiseless harmony of the whole action which we should admire, and which only makes itself known in the total result.—
Clausewitz, On War, Book III, Chapter 1
