War is merely a continuation of politics.

Knowledge in war is very simple, being concerned with so few subjects, and only with their final results at that. But this does not make its application easy.

In 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.

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.

Two qualities are indispensable: first, an intellect that, even in the darkest hour, retains some glimmerings of the inner light which leads to truth; and second, the courage to follow this faint light wherever it may lead.

By 'intelligence' we mean every sort of information about the enemy and his country - the basis, in short, of our own plans and operations.

A certain grasp of military affairs is vital for those in charge of general policy.
