This classic work of scholarship scrutinizes all aspects of Roman military forces throughout the Roman Empire, in Europe, North Africa, and the Near and Middle East. Graham Webster describes the Roman army's composition, frontier systems, camps and forts, activities in the field (including battle tactics, signaling, and medical services), and peacetime duties, as well as the army's overall influence in the Empire. First published in 1969, the work is corrected and expanded in this third edition, which includes new information from excavations and the finding of contemporary scholars. Hugh Elton provides an introduction surveying scholarship on the Roman army since the last edition of 1985.

"Unique in its coverage of the physical, organizational and cultural aspects of the Roman army. . . . The book is handsomely produced and generously illustrated with thirty excellent plates and over fifty line drawings and plans." - Ronald Mellor, Classical World
