Why did Cyrus Thorpe include war finance and manufacturing in his idea of logistics?

In his 1917 work Pure Logistics, U.S. Marine officer Cyrus Thorpe expanded the definition of logistics to include war finance, ship construction, and munitions manufacture because he viewed logistics as the third member of a fundamental "strategy-tactics-logistics" trinity.1

Rather than limiting the term to traditional supply and transportation, Thorpe argued that the logical function of logistics was to provide all human and material means necessary for the conduct of war. By incorporating war economics and industrial mobilization into his framework, Thorpe recognized that modern warfare required the total integration of a nation's economic foundations to sustain military operations. This perspective reflected a broader shift in military thought during the industrial era, where the scale of mobilization and the complexity of weapons technology necessitated that logistics encompass the entire process of transforming national resources into military power.12
