As the rush of rock-shouldering torrents, so is the spirit of the troops.
Like the well-judged flight of the falcon, in a flash crushing its quarry, so should the stroke be timed.
Wherefore the spirit of the good fighter is terrifying, his occasions sudden; like the stretched cross-bow, whose string is released at the touch of the trigger.
In the maze and tumult of the battle, there is no confusion; in the thick of action the battle array is impenetrable.
If discipline be perfect, disorder can be simulated; if truly bold, we can feign fear; if really strong, we can feign weakness.
We simulate disorder by subdivision; fear, by spirit; weakness, by battle formation.
We set the enemy in motion by adopting different formations to which he must conform.
If we offer the enemy a point of advantage, he will certainly take it: we give him an advantage, set him in motion and then fall upon him.
