This is the law of strategic siege. If you are equal, then fight if you are able. If youare fewer, then keep away if you are able. If you are not as good, then flee if you are able. Therefore if the smaller side is stubborn, it becomes the captive of the larger side.
Generals are assistants of the nation.
When their assistance is complete, the country is strong. When their assistance is defective, the country is weak. So there are three ways in which a civil leadership causes the military trouble. When a civil leadership unaware of the facts tells its armies to advance when it should not, or tells its armies to retreat when it should not, this is called tying up the armies. When the civil leadership is ignorant of military affairs but shares equally in the government of the armies, the soldiers get confused.
