Spanning from Adrianople (378) to Marignano (1515), Charles Oman's classic surveys the long transformation of European warfare from late Roman and Byzantine paradigms through the ascendancy of the mailed knight to the infantry revolutions of the longbowman, the Swiss pike, and early gunpowder. In lucid Victorian prose, Oman interweaves battle narratives-Hastings, Bouvines, Courtrai, Crécy, and Agincourt-with analysis of recruitment, armament, and command to show how social institutions molded tactics. His comparative method, grounded in close reading of chronicles, places the book at the birth of professional military historiography. A scholar of vast range and later Chichele Professor of Modern History at Oxford, Oman brought philological rigour and a campaign historian's eye to medieval sources. His training amid late nineteenth-century debates on feudalism and state formation, and his lifelong interest in tactical evolution, shaped a project intent on disentangling legend from practice. This work remains indispensable for students of medieval studies, military history, and the history of technology. Even where subsequent archaeology and source criticism have refined particular conclusions, Oman's sweep, clarity, and taxonomic insight make the book a reliable scaffolding for further study and an invigorating guide to how Europeans learned to fight across a millennium.
