There is nothing more common than to find considerations of supply affecting the strategic lines of a campaign and a war.

War should never be thought of as something autonomous, but always as an instrument of policy.

Strength of character does not consist solely in having powerful feelings, but in maintaining one's balance in spite of them.

It should be noted that the seeds of wisdom that are to bear fruit in the intellect are sown less by critical studies and learned monographs than by insights, broad impressions, and flashes of intuition.

Knowledge must become capability.

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