What do we mean by the defeat of the enemy? Simply the destruction of his forces, whether by death, injury, or any other means-either completely or enough to make him stop fighting. . . . The complete or partial destruction of the enemy must be regarded as the sole object of all engagements. . . . Direct annihilation of the enemy's forces must always be the dominant consideration.
Carl von ClausewitzIn 1793 such a force as no one had any conception of made its appearance. War had again suddenly become an affair of the people, and that of a people numbering thirty millions, every one of whom regarded himself as a citizen of the State... By this participation of the people in the war... a whole Nation with its natural weight came into the scale.
Carl von ClausewitzAny complex activity, if it is to be carried on with any degree of virtuosity, calls for appropriate gifts of intellect and temperament. If they are outstanding and reveal themselves in exceptional achievements, their possessor is called a 'genius'.
Carl von ClausewitzTalent and genius operate outside the rules, and theory conflicts with practice.
Carl von ClausewitzNo other human activity is so continuously or universally bound up with chance. And through the element of chance, guesswork and luck come to play a great part in war.
Carl von ClausewitzLastly, the great uncertainty of all data in War is a peculiar difficulty, because all action must, to a certain extent, be planned in a mere twilight, which in addition not unfrequently — like the effect of a fog or moonshine — gives to things exaggerated dimensions and an unnatural appearance.
