No general answer can be given to the question: "In what detail shall the orders be?" The general statement can be made, however, that the instructions should be confined as closely as practicable to a statement of the department's desires, and that this statement should be as clear as possible. If, for instance, the only desire of the department is that the enemy's fleet shall be defeated, no amplification of this statement is required. But if the department should desire, for reasons best known to itself, that the enemy should be defeated by the use of a certain method, then that should be stated also. Maybe it would not be wise for the department to state the method the employment of which is desired; maybe the commander-in-chief would be the best judge of the method to be employed. But maybe circumstances of governmental policy dictate the employment of a certain method, even if militarily it is not the best; and maybe also the department might prefer that method by reason of information recently received, which it does not have time to communicate in full. Now, if it is desirable for the department to give the commander-in-chief instructions, running the risk of invading his "area of discretion," and of doing other disadvantageous things, it is obvious that the department should be thoroughly equipped for doing it successfully. This means that the department should be provided not only with the most efficient radio apparatus that can be secured, manned, of course, by the most skilful operators, but also with a body of officers capable of handling that particular part of the Navy Department's work which is the concentrated essence of all its work, the actual handling of the naval forces. The usual name given to such a body of officers is "General Staff."
