This book examines the strategies and military tactics of the Byzantines and their enemies in Eastern Anatolia, Syria and in Upper Mesopotamia in the tenth century. This period of conflict is difficult to define: it was too inactive to be called a 'war' but too active to be called a 'cold war'. Nevertheless, it was a 'war', even if it lacked the numerous pitched battles or protracted sieges that defined other periods or other operational theatres of war. This study examines the way the Byzantines innovated and adapted their strategies and tactics to those of their enemies in the East, giving a rich picture of tenth-century Byzantine warfare.
