BC: Histories of espionage often begin with references to spying in the Old Testament and ancient Greece and Rome.
400s BC: Sun Tzu's (Master Sun) Art of War (audiobook) discusses the "use of spies" in its last chapter, "use of spies." (I recommended watching this 7-minute commentary before continuing.) Master Sun claims not giving honors and spending money to gain "foreknowledge" of the enemy is the "height of inhumanity." A general who doesn't use spies "is no leader on men, no present help to his sovereign, no master of victory." Spies determine an army's ability to move. 
  • Master Sun describes five types of spies.
    1. Local spies: Employ local inhabitants with local knowledge
    2. Inward spies: Recruit enemy officials
    3. Converted spies: Find, bribe and treat well enemy spies turning them into double agents working for you. Converted spies help identify and employ local and inward spies. Converted spies provide information for creating successful deceptions promoted by doomed spies.
    4. Doomed spies: Practice open deceptions your spies report to the enemy. Former DCI Allan Dulles suggests these spies are "doomed" because the enemy will probably kill them when the deception because apparent.
    5. Surviving spies: Send spies to bring back information about the enemy
  • These spies work together create a" secret system no one can discover," called "divine manipulation of the threads."
  • These spies should have close contact with leaders.
  • These spies should be well rewarded. 
  • Spies must be used wisely, with benevolence and straightforwardness.
  • Analyze spy's reports carefully, aware that reports may be accidentally or intentionally misleading. 
  • If spies reveal information before the time is ripe, that spy and the person told must be put to death.
