Histories of the Hundred Years War have been written, and accounts of the famous battles, but until now no book has concentrated on the sieges that played a decisive role in the protracted struggle between England and France. Edward III's capture of Calais in 1347 was of crucial importance for the English, and the failure of the English siege of Orleans in 1429 was a turning point for the French after the disaster of Agincourt. Throughout the war, sieges were a major weapon in the strategic armouries of both sides, and Peter Hoskins's perceptive and graphic study is a fascinating analysis of them.

He describes the difficulties faced by besieger and besieged, examines the logistics and resource implications of sieges, and provides a comparative assessment of siege warfare alongside set-piece battles and the English strategy of chevauchees. Key sieges are reconstructed in vivid detail, other sieges are summarized, and the book is fully illustrated with photographs and plans.
