It improves the sending and receiving of news and instructions, both for the commander at sea and for his department at home; but it does it more effectively for the department than for the man at sea, because of the superior facilities for large and numerous apparatus that shore stations have, and their greater freedom from interruptions of all kinds.
This condition tends to place the strategical handling of all the naval machine, including the active fleet itself, more in the hands of the department or admiralty, and less in the hands of the commander-in-chief: and this tendency is confirmed by the superior means for discussion and reflection, and for trial by war games, that exist in admiralties, compared with those that exist in ships.
The general result is to limit the commander-in-chief more and more in strategical matters: to confine his work more and more to tactics.
Such a condition seems reasonable in many ways.

The government decides on a policy, and tells the Navy Department to carry it out, employing the executive offices and bureaus to that end, under the guidance of strategy.

Strategy devotes itself during peace to designing and preparing the naval machine, and in war to operating it, utilizing both in war and peace the bureaus and offices and the fleet itself.

And in the same way as that in which the bureaus and offices perform the calculations and executive functions of logistics, for furnishing the necessary material of all kinds, the fleet performs those of tactics.

From this point of view, strategy plans and guides all the acts of navies, delegating one part of the practical work needed to carry out those plans to logistics, and the other part to tactics.
Operating the naval machine in war means practically operating the active fleet in such a way as to cause victories to occur, to cause the fleet to enter each battle under as favorable conditions as practicable, and to operate the other activities of the navy in such a way that the fleet will be efficiently and promptly supplied with all its needs.
