and harmonise the different elements thereof before pitching his camp.
["Chang Yu says: "the establishment of harmony and confidence between
the higher and lower ranks before venturing into the field;" and he
quotes a saying of Wu Tzŭ (chap. 1 ad init.): "Without harmony in the
State, no military expedition can be undertaken; without harmony in the
army, no battle array can be formed." In an historical romance Sun Tzŭ
is represented as saying to Wu Yuan: "As a general rule, those who are
waging war should get rid of all the domestic troubles before
proceeding to attack the external foe."]
