Inspirational Quotes on Spies

“It is essential to seek out enemy agents who have come to conduct espionage against you and to bribe them to serve you. Give them instructions and care for them. Thus doubled agents are recruited and used. It is by means of the doubled agent that native and inside agents can be recruited and employed. This is because the doubled agent knows those of his own countrymen who are covetous as well as those officials who have been remiss in office. These we can tempt into our service. And it is by this means that the expendable agent, armed with false information, can be sent to convey it to the enemy. It is because doubled agents know in what respects the enemy can be deceived that expendable agents may be sent to convey false information. It is by this means also that living agents can be used at appropriate times. The sovereign must have full knowledge of the activities of the five sorts of agents. This knowledge must come from the doubled agents, and therefore it is mandatory that they be treated with the utmost liberality. And therefore only the enlightened sovereign and the worthy general who are able to use the most intelligent people as agents are certain to achieve great things.”

“Secret operations are essential in war; upon them the army relies to make its every move. An army without secret agents is exactly like a man without eyes or ears.”

“The reason the enlightened prince and the wise general conquer the enemy whenever they move and their achievements surpass those of ordinary men is foreknowledge. What is called 'foreknowledge' cannot be elicited from spirits, nor from gods, nor by analogy with past events, nor from calculations. It must be obtained from men who know the enemy situation. There are five sorts of secret agents to be employed. These are native, inside, doubled, expendable, and living. When these five types of agents are all working simultaneously and none knows their method of operation they are called 'The Divine Skein' and are the treasure of a sovereign. Native agents are those of the enemy's country people whom we employ. Inside agents are enemy officials whom we employ. Among the official class there are worthy men who have been deprived of office; others who have committed errors and have been punished. There are sycophants and minions who are covetous of wealth. There are those who wrongly remain long in lowly office; those who have not obtained responsible positions, and those whose sole desire is to take advantage of times of trouble to extend the scope of their own abilities. There are those who are two-faced, changeable, and deceitful, and who are always sitting on the fence. As far as all such are concerned you can secretly inquire after their welfare, reward them liberally with gold and silk, and so tie them to you. Then you may rely on them to seek out the real facts of the situation in their country, and to ascertain its plans directed against you. They can as well create cleavages between the sovereign and his ministers so that these are not in harmonious accord. Doubled agents are enemy spies whom we employ. When the enemy sends spies to pry into my accomplishments or lack of them, I bribe them lavishly, turn them around, and make them my agents. Expendable agents are those of our own spies who are deliberately given fabricated information. We leak information which is actually false and allow our own agents to learn it. When these agents operating in enemy territory are taken by him they are certain to report this false information. The enemy will believe it and make preparations accordingly. But our actions will of course not accord with this, and the enemy will put the spies to death. Sometimes we send agents to the enemy to make a covenant of peace and then attack.”
