The Use Of Spies

Sunzi XIII. 5.


有生間	有死間	有反間	有內間	有因間	有五	故用間

Hence the use of spies, of whom there are five classes: 1) Local spies; 2) inward spies; 3) converted spies; 4) doomed spies; 5) surviving spies.

Giles XIII.7.

Le grand secret de venir à bout de tout consiste dans l'art de savoir mettre la division à propos ; division dans les villes et les villages, division extérieure, division entre les inférieurs et les supérieurs, division de mort, division de vie.
