Meaning of “Rapidity is the essence of war: take advantage…”
Speed matters when it exploits a temporary opening; the point is timely movement into weakness, not haste without information or purpose.
Where does it come from?
The Art of War, Chapter XI 'The Nine Situations,' section 19, Lionel Giles translation (1910), original scan leaf 178 / printed page 122. 'Rapidity is the essence of war' introduces the instruction to exploit unreadiness, unexpected routes and unguarded positions; it remains historical battlefield strategy, not current operational guidance.
