The Art of War by active 6th century B.C. Sunzi

Sun Tzu Wu was a native of the Chi State. His ART OF WAR brought him to the notice of Ho Lu, [2] King of Wu. Ho Lu said to him: "I have carefully perused your 13 chapters. May I submit your theory of managing soldiers to a slight test" Sun Tzu replied: "You may." Ho Lu asked: "May the test be applied to women" The answer was again in the affirmative, so arrangements were made to bring 180 ladies out of the Palace. Sun Tzu divided them into two companies, and placed one of the King's favorite concubines at the head of each. He then bade them all take spears in their hands, and addressed them thus: "I presume you know the difference between front and back, right hand and left hand" The girls replied: Yes. Sun Tzu went on: "When I say "Eyes front," you must look straight ahead. When I say "Left turn," you must face towards your left hand. When I say "Right turn," you must face towards your right hand. When I say "About turn," you must face right round towards your back." Again the girls assented. The words of command having been thus explained, he set up the halberds and battle-axes in order to begin the drill. Then, to the sound of drums, he gave the order "Right turn." But the girls only burst out laughing. Sun Tzu said: "If words of command are not clear and distinct, if orders are not thoroughly understood, then the general is to blame."
