Hence a commander who advances without any thought of winning personal fame and withdraws in spite of certain punishment, whose only concern is to protect his people and promote the interests of his ruler, is the nation's treasure. Because he fusses over his men as if they were infants, they will accompany him into the deepest valleys; because he fusses over his men as if they were his own beloved sons, they will die by his side. If he is generous with them and yet they do not do as he tells them, if he loves them and yet they do not obey his commands, if he is so undisciplined with them that he cannot bring them into proper order, they will be like spoiled children who can be put to no good use at all.
