His detailed analysis of battles provides an important reassessment of the way in which infantry and dismounted cavalry achieved such striking successes. HISTORY This remarkable study confirms (DeVries's) emergence as one of the major scholars of his generation. JOURNAL OF MILITARY HISTORY This study departs from the conventional view of the dominance of cavalry in medieval warfare: its objective is to establish the often decisive importance of infantry. Kelly DeVries employs evidence from first-hand accounts - a major feature of this study - to examine the role of the infantry, and the nature of infantry tactics, in nineteen battles fought in England and Europe between 1302 and 1347, in most of which it was the infantry which secured victory. The battles analysed in detail are: Courtrai Arques Mons-en-Pevele Loudon Hill Kephissos Bannockburn Boroughbridge Cassel Dupplin Moor Halidon Hill Laupen Morlaix Staveren Vottem Crecy Neville's Cross, and the infantry ambushes: Morgarten Auberoche La Roche-Derrien.
