Ground which can be freely traversed by both sides is called accessible.

It is sufficient to estimate the enemy situation correctly and to concentrate your strength to capture him. There is no more to it than this. He who lacks foresight and underestimates his enemy will surely be captured by him.

Birds rising in flight is a sign that the enemy is lying in ambush; when the wild animals are startled and flee he is trying to take you unaware.

Know the enemy, know yourself; your victory will never be endangered. Know the ground, know the weather; your victory will then be total.

The expert in battle seeks his victory from strategic advantage and does not demand it from his men.

Victory is the main object in war.

When he pretends to flee, do not pursue.
