The first and most important rule to observe...is to use our entire forces with the utmost energy. The second rule is to concentrate our power as much as possible against that section where the chief blows are to be delivered and to incur disadvantages elsewhere, so that our chances of success may increase at the decisive point. The third rule is never to waste time. Finally, the fourth rule is to follow up our successes with the utmost energy. Only pursuit of the beaten enemy gives the fruits of victory.
Carl von ClausewitzWe must evaluate the political sympathies of other states and the effect war may have on them. To assess these things in all their ramifications and diversity is plainly a colossal task. Rapid and correct appraisal of them clearly calls for the intuition of a genius; to master all this complex mass by sheer methodical examination is obviously impossible. Bonaparte was quite right when he said that Newton himself would quail before the algebraic problems it could pose.
Carl von ClausewitzNo one starts a war--or rather, no one in his sense ought to do so--without first being clear in his mind what he intends to achieve by the war and how he intends to conduct it.
Carl von ClausewitzWe must, therefore, be confident that the general measures we have adopted will produce the results we expect. most important in this connection is the trust which we must have in our lieutenants. consequently, it is important to choose men on whom we can rely and to put aside all other considerations. if we have made appropriate preparations, taking into account all possible misfortunes, so that we shall not be lost immediately if they occur, we must boldly advance into the shadows of uncertainty.
