 1. Sun Tzu said: The control of a large force
  is the same principle as the control of a few men: 
  it is merely a question of dividing up their numbers.

 2. Fighting with a large army under your command
  is nowise different from fighting with a small one: 
  it is merely a question of instituting signs and signals.

 3. To ensure that your whole host may withstand
  the brunt of the enemy's attack and remain unshaken--
  this is effected by maneuvers direct and indirect.

 4. That the impact of your army may be like a grindstone
  dashed against an egg--this is effected by the science
  of weak points and strong.

 5. In all fighting, the direct method may be used
  for joining battle, but indirect methods will be needed
  in order to secure victory.
