On 13 September 1356 near Poitiers in western France, the small English army of Edward, the Black Prince crushed the forces of the French King Jean II in one of the most famous battles of the Hundred Years' War. Over the centuries the story of this against-the-odds English victory has, along with Crécy and Agincourt, become part of the legend of medieval warfare. And yet in recent times this classic battle has received less attention than the other celebrated battles of the period. The time is ripe for a reassessment, and this is the aim of Christian Teutsch's thought-provoking new account.

The author outlines the development of the undisciplined barbarian war bands of the Dark Ages into the feudal armies of the early Middle Ages. It deals with the arms and equipments of the soldier, not only from surviving specimens but also from descriptions in contemporary medieval documents. Vesey Norman covers the slow development of tactics and the transition of the warrior from a personal follower of a war leader to the knight who served his feudal overlord as a heavily armoured cavalryman in return for land. He details the attitude of the Church to warfare, the rise of chivalry and the development of the knights of the military orders, the Templars, the Hospitallers and the Teutonic Knights. He answers such questions as what classes of men made up the army, who commanded them, and how they were equipped, paid and organized.
