A general who allows himself to be decisively defeated in an extended mountain position deserves to be court-martialled.
Carl von ClausewitzThe world has a way of undermining complex plans. This is particularly true in fast moving environments. A fast moving environment can evolve more quickly than a complex plan can be adapted to it. By the time you have adapted, the target has changed.
Carl von ClausewitzThe political object is the goal, war is the means of reaching it, and the means can never be considered in isolation form their purposes.
Carl von ClausewitzWhat 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.
