for the brave to advance alone, or for the cowardly to retreat alone.
[Chuang Yu quotes a saying: "Equally guilty are those who advance
against orders and those who retreat against orders." Tu Mu tells a
story in this connection of Wu Ch’i, when he was fighting against the
Ch’in State. Before the battle had begun, one of his soldiers, a man of
matchless daring, sallied forth by himself, captured two heads from the
enemy, and returned to camp. Wu Ch’i had the man instantly executed,
whereupon an officer ventured to remonstrate, saying: "This man was a
good soldier, and ought not to have been beheaded." Wu Ch’i replied: "I
fully believe he was a good soldier, but I had him beheaded because he
acted without orders."]
This is the art of handling large masses of men.
