its proper function in a plan of war; it will enable each service to
realise the better the limitations and the possibilities of the function
with which it is charged, and how and when its own necessities must give
way to a higher or more pressing need of the other. It discloses, in short,
that naval strategy is not a thing by itself, that its problems can seldom
or never be solved on naval considerations alone, but that it is only a
part of maritime strategy--the higher learning which teaches us that for a
maritime State to make successful war and to realise her special strength,
army and navy must be used and thought of as instruments no less intimately
connected than are the three arms ashore.

It is for these reasons that it is of little use to approach naval strategy
except through the theory of war. Without such theory we can never really
understand its scope or meaning, nor can we hope to grasp the forces which
most profoundly affect its conclusions.
