How did Henri de Jomini separate strategy, tactics, and logistics?

Henri, baron de Jomini was a foundational figure in modern military thought who, for the first time, successfully established clear divisions between strategy, tactics, and logistics.1

In his seminal work, Summary of the Art of War, Jomini defined these elements as follows:

• Strategy: Jomini viewed this as the art of making war upon a map, focusing on the "choice of correct lines of operation" to dominate a zone of conflict. It is the overarching planning that dictates where and why military forces are engaged.1
• Tactics: While Jomini’s primary interest was strategy, he categorized tactics as the execution of maneuvers on the battlefield, distinct from the broader strategic planning.12
• Logistics: Jomini defined this as "the practical art of moving armies," encompassing the full range of functions required to sustain and maneuver forces, such as planning, administration, supply, billeting, and road construction.2

Jomini conceptualized logistics as the "science of generals" and their staffs, serving as the essential bridge that allowed for the execution of strategic and tactical combinations. By formalizing these distinctions, he transformed the study of war into a systematic discipline governed by rules and principles.231
