Osprey's elite title on the rise and fall of European medieval cavalry during an 800 year period. After the fall of the Western Roman Empire there was a decline in professional cavalry forces, and infantry dominated in the Germanic successor barbarian kingdoms. In the Carolingian and Norman periods from the 9th to the 11th centuries, under the impact of Viking, Saracen and Magyar advances, the cavalry arm gradually expanded from the small remaining aristocratic elite. Even so, the supposedly complete dominance of the knight in the 12th and 13th centuries is grossly exaggerated, as integrated cavalry and infantry tactics were nearly always the key to success. This is the first in a two-part treatment of medieval tactics, covering developments in both cavalry and infantry tactics. Throughout the period there was a steady evolution of training in both individual and unit skills, of armor and weapons, and thus of tactics on the battlefield. This book covers key moments in this story of evolution from Hastings in 1066 to Legnano in 1176. It also details the later development of cavalry versus cavalry tactics and the two key set piece battles of Bouvines in 1214 and Pelagonia in 1259, the former an example of abject failure of cavalry tactics and the latter a stunning success.

By about 1260 the steady rise of the European heavily armoured mounted knight to the predominant role in most pitched battles was complete. But though he dominated the actual day of battle, he did not dominate warfare - there were plenty of vital though unglamorous tasks for which footsoldiers were still necessary, 'cleaning up round the edges'. With the development in the 13th century of co-operative tactics using crossbowmen and heavy spearmen, deployed together to compensate for each others' vulnerabilities, circumstance began to arise in which the charge by Muslim horse-archers, and then by European armoured knights, could be defied. Infantry were far cheaper and easier to train than knights, and potentially there were far more of them. Slowly, tactics emerged by which more numerous and more varied infantry played an increasing part in battles. The best-known examples of this 'democratization of the battlefield' are the English longbowmen who won battles against French knights in the Hundred Years' War, and the massed Swiss spearmen and halberdiers who did the same in wars against the Dukes of Burgundy. Illustrated with specially commissioned full-colour artwork depicting the tactical formations of the era, this book traces these and other examples of this 'jerky' and uneven process through its regional differences, which were invariably entwined with parallel cavalry developments - the balanced army of 'mixed arms' was always the key to success. By the time serious hand-held firearms appeared on battlefields in large numbers in about 1500, the face of medieval warfare had been transformed.
