So the important thing in a military operation is victory, not persistence.
Of all those in the army close to the commander none is more intimate than the secret agent; of all rewards none more liberal than those given to secret agents; of all matters none is more confidential than those relating to secret operations.
According to my assessment, even if you have many more troops than others, how can that help you to victory?
One who sets the entire army in motion to chase an advantage will not attain it.
Can you imagine what I would do if I could do all I can?
These military devices, leading to victory, must not be divulged beforehand.
Plan for what it is difficult while it is easy, do what is great while it is small.
When you surround an army, leave an outlet free. Do not press a desperate foe too hard.
Attack him where he is unprepared, appear where you are not expected.
The art of giving orders is not to try to rectify the minor blunders and not to be swayed by petty doubts.
the worst calamities that befall an army arise from hesitation
If he sends reinforcements everywhere, he will everywhere be weak.
