The Science of War

Colonel G.F.R. Henderson was one of the great soldier-scholars of the late Victorian British Army: a gifted historian, strategist and lecturer whose writings shaped the professional education of a generation of officers before the First World War. First published in 1905, The Science of War gathers together Henderson’s most important essays and lectures on warfare, strategy, leadership and military thought, written during the final decade of his life.

This remarkable volume reveals Henderson at the height of his intellectual powers. Moving effortlessly between theory and history, he examines the nature of strategy, the tactical employment of cavalry, the relationship between morale and firepower, and the enduring principles of command. His studies of Wellington, the American Civil War, Gettysburg and the Wilderness Campaign remain among the finest examples of military analysis in the English language. Throughout, Henderson demonstrates his conviction that war could never be reduced to mechanical formulae: judgement, leadership, initiative and moral force remained decisive.

Few British military thinkers of the period exercised greater influence. As Professor of Military Art and History at the Staff College, Camberley, Henderson helped shape the minds of many officers who would later command during the First World War. His famous biography Stonewall Jackson and the American Civil War established his international reputation, but The Science of War perhaps offers the clearest insight into the intellectual framework that underpinned all his work. Here the reader encounters not merely a historian, but a profound interpreter of warfare itself.

At a time when European armies were grappling with the implications of industrial warfare, mass mobilisation and modern firepower, Henderson insisted that military history remained indispensable as a training ground for the commander’s mind. Officers, he argued, must learn not only technical proficiency, but how to think under pressure, interpret uncertainty and understand the human dimensions of combat. His writings therefore stand at the crossroads between the warfare of Napoleon and the industrial conflicts of the twentieth century.
