11. The Nine Situations
Asked if an army can be made to imitate the SHUAI-JAN,
That is, as Mei Yao-ch`en says, "Is it possible to make the front and rear of an army each swiftly responsive to attack on the other, just as though they were part of a single living body?"
Cf. VI. ss. 21.
The meaning is: If two enemies will help each other in a time of common peril, how much more should two parts of the same army, bound together as they are by every tie of interest and fellow-feeling. Yet it is notorious that many a campaign has been ruined through lack of cooperation, especially in the case of allied armies.
