CONCLUDING REMARKS, BOOK I.
THOSE things which as elements meet together in the atmosphere of War and make it a resistant medium for every activity we have designated under the terms danger, bodily effort (exertion), information, and friction.

In their impedient effects they may therefore be comprehended again in the collective notion of a general friction.

Now is there, then, no kind of oil which is capable of diminishing this friction?
Only one, and that one is not always available at the will of the Commander or his Army.

It is the habituation of an Army to War.
Habit gives strength to the body in great exertion, to the mind in great danger, to the judgment against first impressions.
