The natural formation of the country is the soldier's best ally
The nature of war is constant change.
He will win who, prepared himself, waits to take the enemy unprepared.
If I wish to engage, then the enemy, for all his high ramparts and deep moat, cannot avoid engagement; I attack that which he is obliged to rescue.
Who can determine where one ends and the other begins?
He who relies solely on warlike measures shall be exterminated; he who relies solely on peaceful measures shall perish.
