Attack is the secret of defense; defense is the planning of an attack.
Great results, can be achieved with small forces.
There are routes not to be followed, armies not to be attacked, citadels not to be besieged, territory not to be fought over.
Quickness is the essence of the war.
If quick, I survive. If not quick, I am lost. This is death.
In warfare, there are no constant conditions. He who can modify his tactics in relation to his opponent will succeed and win.
