This study of the English sieges from the Norman Conquest to the end of the War of the Roses examines the evolution of siege warfare & the events that culminated with each siege. The skills of the engineer, the architect, and the miner are as important to Warner's theme as the courage of the troops & the strategies of their commanders. Investigates Wallingford, Ch teau Gaillard, Bedford, and Rouen—sieges that decided far more in history than the campaigns they climaxed.
