"If laws and orders be not clear; if rewards and punishments be not just; if the bell be sounded and they halt not, or drum be beaten and men do not advance; even if there be a hundred thousand men at arms, they are of no avail. "Where there is order, then there is propriety at rest, and dignity in motion; none can withstand the attack, and retreat forbids pursuit; motion is regulated, and movements to right and left are made in answer to the signal; if the ranks be cut asunder, formation is preserved; if scattered, they are maintained; in fortune or in danger, there is unity; if a number be collected, they cannot be separated; they may be used but not wearied; in whatever situation they are placed, nothing under heaven can withstand them. The army may be called a father and his children." And Wu said:-- "In marching, movements and halts must be properly adjusted, suitable occasions for rationing not missed; the strength of men and horses not exhausted. If these three things be observed, the commands of the superior can be carried out; if the commands of the superior be carried out, order is maintained. If advances and halts be without method, victualling unsuitable, horses and men tired and weary--neither unsaddled or housed--it is because the orders cannot be obeyed; if the orders be set aside, there is disorder in the camp, and in battle--defeat." Wu the Master said:-- "On that depository of corpses, the battlefield, if there be certain expectation of death, there is life; if there be happy expectation of life, there is death. The good general is like unto one sitting in a leaking ship, or lying under a burning roof; the wisest man cannot contrive against him; the strongest man cannot destroy his composure; and the enemy's onslaught can be withstood. For procrastination is the greatest enemy of the general; disasters to the army are born of indecision." Wu the Master said:-- "Men meet their death from lack of ability or unskilfulness. Wherefore training is the first requirement of war. One man with a knowledge of war can teach ten; ten men skilled in war can teach one hundred; one hundred can teach one thousand; one thousand can teach ten thousand; and ten thousand men can train an army. "An enemy from a distance should be awaited, and struck at short range; an enemy that is tired should be met in good order; hunger should be opposed by full bellies; the battle formation should be round or square, the men should kneel or stand; go or remain; move to the right or left; advance or retire; concentrate or disperse; close or extend when the signal is given. "All these changes must be learnt, and the weapons distributed. This is the business of the general." Wu the Master said:--
