Naval Warfare on the High Seas p.71

To be sure, naval warfare is not conducted in a vacuum. It is not separate from larger strategic considerations that are always centered on land and involve, ultimately, military campaigns on land. Almost never have naval operations been conducted independently of ,and without regard to, land operations or objectives
In fact, since opposing naval and air forces execute simultaneous movement, the location of such forces in relation to one another is constantly changing. Therefore, it would seem that relative location would be more important than absolute location in naval warfare on the hight seas. While this may be true at the tactical level, the latter ulitimately determines the strategic framework of naval warfare. It dictates the "geostrategic centers of gravity" in a conflict at sea, which in turn, determines where and how command of the sea must be secured in order to achieve strategic objectives.
