  1. 故夜戰多火鼓晝戰多旌旗所以變民之耳目也
  2. 故三軍可奪氣將軍可奪心


This is the art of handling large masses of men.

26. In night-fighting, then, make much use of signal-fires and drums, and in fighting by day, of flags and banners, as a means of influencing the ears and eyes of your army.

The T‘ung Tien has the bad variant 便 for . With regard to the latter word, I believe I have hit off the right meaning, the whole phrase being slightly elliptical for “influencing the movements of the army through their senses of sight and hearing.” Li Ch‘üan, Tu Mu and Chia Lin certainly seem to understand it thus.

It is in this way that they may be robbed of their keen spirit.” Li Ch‘üan and others tell an anecdote (to be found in the Tso Chuan,
