Victory is reserved for those who are willing to pay its price.
A wise general makes a point of foraging of the enemy.
Without local guides, your enemy employs the land as a weapon against you.
The nature of war is constant change.
If you are situated at a great distance from the enemy, and the strength of the two armies is equal, it is not easy to provoke a battle, and fighting will be to your disadvantage.
To perceive victory when it is known to all is not really skilful. Everyone calls victory in battle good, but it is not really good.
