The more closely [the German army] converged on [Stalingrad], the narrower became their scope for tactical manoeuvre as a lever in loosening resistance. By contrast, the narrowing of the frontage made it easier for the defender to switch his local reserves to any threatened point on the defensive arc.

For whoever habitually suppresses the truth in the interests of tact will produce a deformity from the womb of his thought.

In war the chief incalculable is the human will, which manifests itself in resistance, which in turn lies in the province of tactics. Strategy has not to overcome resistance, except from nature. Its purpose is to diminish the possibility of resistance, and it seeks to fulfil this purpose by exploiting the elements of movement and surprise.

While the nominal strength of a country is represented by its numbers and resources, this muscular development is dependent on the state of its internal organs and nerve-system - upon its stability of control, morale, and supply.

The easiest and quickest path into the esteem of traditional military authorities is by the appeal to the eye, rather than to the mind. The `polish and pipeclay' school is not yet extinct, and it is easier for the mediocre intelligence to become an authority on buttons, than on tactics.

While there are many causes for which a state goes to war, its fundamental object can be epitomized as that of ensuring the continuance of its policy - in face of the determination of the opposing state to pursue a contrary policy. In the human will lies the source and mainspring of conflict.

In reality, it si more fruitful to wound than to kill. While the dead man lies still, counting only one man less, the wounded man is a progressive drain upon his side.
