Administration and Organization of War in Thirteenth-Century England [PDF ebook] 

The essays brought together in this volume examine the conduct of war by the Angevin kings of England during the long thirteenth century (1189-1307). Drawing upon a wide range of unpublished administrative records that have been largely ignored by previous scholarship, David S. Bachrach offers new insights into the military technology of the period, including the types of artillery and missile weapons produced by the royal government. The studies in this volume also highlight the administrative sophistication of the Angevin kings in military affairs, showing how they produced and maintained huge arsenals, mobilized vast quantities of supplies for their armies in the field, and provided for the pastoral care of their men. Bachrach also challenges the knight-centric focus of much of the scholarship on this period, demonstrating that the militarization of the English population penetrated to men in the lower social and economic strata, who volunteered in large numbers for military service, and even made careers as professional soldiers.
