First Lensman by E.E. Smith

As long as they were commodores, Clayton of North America and Schweikert of Europe had stayed fairly close to the home planet except for infrequent vacation trips. With the formation of the Galactic Patrol, however, and their becoming Admiral and Lieutenant-Admiral of the First Galactic Region, and their acquisition of Lenses, the radius of their sphere of action was tremendously increased. One or the other of them was always to be found in Grand Fleet Headquarters at New York Spaceport, but only very seldom were both of them there at once. And if the absentee were not to be found on Earth, what of it? The First Galactic Region included all of the solar systems and all of the planets adherent to Civilization, and the absentee could, as a matter of business and duty, be practically anywhere.

Usually, however, he was not upon any of the generally-known planets, but upon Bennett -- getting acquainted with the officers, supervising the drilling of Grand Fleet in new maneuvers, teaching classes in advanced strategy, and holding skull-practice generally. It was hard work, and not too inspiring, but in the end it paid off big. They knew their men; their men knew them. They could work together with a snap, a smoothness, a precision otherwise impossible; for imported top brass, unknown to and unacquainted with the body of command, can not have and does not expect the deep regard and the earned respect so necessary to high morale.
