A beaten general is disgraced forever.

The unknown is the governing principle of war.

All the same, the fundamental truths which govern that art are still unchangeable; just as the principles of mechanics must always govern architecture, whether the building be made of wood, stone, iron or concrete; just as the principles of harmony govern music of whatever kind. It is still necessary, then, to establish the principles of war.

Aviation is fine as a sport. But as an instrument of war, it is worthless.

The fundamental qualities for good execution of a plan is first; intelligence; then discernment and judgment, which enable one to recognize the best method as to attain it; the singleness of purpose; and, lastly, . . . stubborn will.

In tactics, action is the governing rule of war.

The military mind always imagines that the next war will be on the same lines as the last. That has never been the case and never will be. One of the great factors on the next war will be aircraft obviously. The potentialities of aircraft attack on a large scale are almost incalculable.
