Matthew Bennett is a Senior Lecturer at The Royal Military Academy Sandhurst.

Spanning some 1,000 years from the fall of the Roman empire in the west to the Reformation, the medieval period was a time of immense diversity in military practice. "The Medieval World at War" brings together for the first time in a single volume authoritative accounts not only European and Middle Eastern warfare, but also of Central Asian, Indian, Chinese and Japanese conflict. It contains vivid accounts of tactics, troop types, battles, fortifications and siege techniques, and examines the underlying political and military strategies that were shaped by the clash of often very different social and ideological systems. Also included are feature boxes on key topics ranging from battles such as Tours, Agincourt and the siege of Constantinople to weaponry and armour from England to Japan, and to castles such as the mighty crusader fortress of Crac des Chevaliers in Syria. Eyewitness accounts bring the story dramatically to life, and battles are visualized with specially commissioned 3-D battle reconstructions.
