This collection gathers together some of the best published work on war in the Middle Ages. The first section of seven papers shows that throughout Europe in the later Middle Ages generals led and armies followed what are usually defined as 'modern' strategy and tactics, contrary to popular belief. The second part reprints nine works that examine the often neglected aspects of the process of putting and keeping together a late medieval army. In the third section the authors discuss various ways that warfare in the fourteenth and fifteenth century affected the society of that period. The final sections cover popular rebellions and crusading.
