The studies in this book examine and illuminate the Anglo-Saxon and Anglo-Norman military institutions that supported and shaped the conduct of war in northwestern Europe in the central middle ages. Taken together, they challenge received opinion on a number of issues and force a profound reconsideration of the manner in which the Normans and their adversaries, Anglo-Saxons, Danes, Angevins and the Welsh, prepared for and waged war.
