Germany realizes this, and therefore has established and followed a system whereby the character of the various material and personnel units of the navy, and even the number of them (under the restrictions of the money alloted), are decided by a body of men who are highly trained in strategy and engineering.
There is an intimate connection between policy and strategy, and therefore between naval policy and naval strategy; and while it is difficult to draw the line exactly which separates policy and strategy, it may be said in general that policy is the concern of the government, and strategy is the concern of the navy and army, to be employed by them to carry out the policy.
As naval policy and naval strategy are so intimately connected in their essence, it is apparent that the naval policy of a country and its naval strategy should be intimately connected in fact; for the policy cannot be properly carried out if the strategy that tries to execute it is not good, or if the policy requires more naval force or skill than the navy can bring to bear; and the strategy cannot be good if it is called upon to execute a policy impossible to execute, or if the exact end in view of the policy is not distinctly known.
Some of the greatest mistakes that have been made by governments have been made because of a lack of co-ordination between the government and its navy, so that the policy and the strategy could not work together.

We see an illustration of this throughout the history of France, whose civil and naval authorities have not worked harmoniously together, whose naval strategy has apparently been opportunistic and short-sighted, and whose navy in consequence has not been so successful as the large sums of money spent upon it might lead one to expect.
Across the English Channel we see a totally different state of things.

In Great Britain the development of the navy has been going on for more than twelve hundred years, ever since King Offa declared that "he who would be secure at home must be supreme at sea." For about eight hundred years thereafter the development was carried on energetically, but in an opportunistic fashion, following the requirements of the hour.

In 1632, however, the Board of Admiralty was established; and with occasional interruptions, especially prior to 1708, the board has continued in existence ever since.
A coherent policy of development has thereby been assured, and a wisdom of strategy established which more than any other single factor has made Great Britain the mistress of the seas, and almost the mistress of the world.
The wisdom of her strategy has been due largely to the fact of the close touch maintained between the civil government, including Parliament, and the navy; for by its very constitution the Board of Admiralty includes some of the highest officers of Parliament, the cabinet, and the navy.

Its presiding officer is a member of the cabinet, and also member of Parliament; four of the officers are naval officers, high in rank, character, and attainments; and the junior civil lord is a civilian versed in naval matters.
