This book explains the tactics and technologies of siege warfare for both attackers and defenders, from ancient times to the beginning of the gunpowder age. Mighty siege engines - including torsion artillery, trebuchets, battering rams and siege towers - are closely examined and illustrated in fine detail. The book discusses the complexities of underground and overground assault, specifically escalade, undermining and sapping, and what happened after a besieging army forced a breach. It also investigates the formalities and deceits of non-force options - the subtle arts of negotiation, spying and infiltration.
