If we read history with an open mind, we cannot fail to conclude that, among all the military virtues, the energetic conduct of war has always contributed most to glory and success.
Carl von ClausewitzWhere execution is dominant, as it is in the individual events of a war whether great or small, then intellectual factors are reduced to a minimum.
Carl von ClausewitzA general in time of war is constantly bombarded by reports both true and false; by errors arising from fear or negligence or hastiness; by disobedience born of right or wrong interpretations, of ill will; of a proper or mistaken sense of duty; of laziness; or of exhaustion; and by accident that nobody could have foreseen. In short, he is exposed to countless impressions, most of them disturbing, few of them encouraging. ... If a man were to yield to these pressures, he would never complete an operation.
