A. T. Mahan offers his opinion on the role of the secretary of the Navy. Mahan believes that the issues within the Navy Department have arisen from its corporate structure and the staff’s knowledge gaps. Mahan observes that there is a lack of “personal responsibility” in the department and argues that the Chief of Staff should be “solely responsible for the information, and for advice, given the Secretary.” Drawing from Julian Stafford Corbett, Mahan discusses the connection between diplomatic and military actions and the necessity of a strong military in peacetime. He concludes by asserting that he does not “advocate or countenance” any actions to weaken the power of the secretary.
