Knowledge of the enemy’s dispositions can only be obtained from other men.

Commentary

The enemy does not want you to know anything about them, just as you will jealously guard your own information and plans.

If you cannot get the knowledge by fair means, it must be gained by subterfuge, including the employment of spies and double agents.
