Principles and rules are intended to provide a thinking man with a frame of reference.

Everything in strategy is very simple, but that does not mean everything is very easy.

However much pains may be taken to combine the soldier and the citizen in one and the same individual, whatever may be done to nationalize wars, never will it be possible to do away with the professionalism of the business; and if that cannot be done, then those who belong to it will always look upon themselves as a kind of guild, in the regulations, laws, and customs in which the "Spirit of War" finds its expression. It would be very wrong to look down upon this corporate spirit, or esprit de corps, which may and should exist more or less in every Army.

If we read history with an open mind, we cannot fail to conclude that, among all the military virtues, the energetic conduct of war has always contributed most to glory and success.

The best form of defense is attack.

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.

There are cases in which the greatest daring is the greatest wisdom.
