The Art of War in the Middle Ages A.D. 378-1515 (Illustrated) (Electronic book text)

"At no time was this interpenetration more complete than in the age which forms the central part of our period. Feudalism, in its origin and development, had a military as well as a social side, and its decline is by no means unaffected by military considerations. There is a point of view from which its history could be described as 'the rise, supremacy, and decline of heavy cavalry as the chief power in war.' To a certain extent the tracing out of this thesis will form the subject of our researches. It is here that we find the thread which links the history of the military art in the middle ages into a connected whole. Between Adrianople, the first, and Marignano, the last, of the triumphs of the mediaval horseman, lie the chapters in the scientific history of war which we are about to investigate."
