The ascent of the Plantagenets to the English throne in 1154 led to the beginning of a new historical phase in the British Isles, which was marked by numerous wars that were fought between the Kingdom of England and the 'Celtic nations' of Wales, Scotland and Ireland. During the rule of the Norman kings, the English armies had not completed the conquest of Wales and had established only some footholds in Ireland; Scotland was still independent and was ready to contest the Plantagenets' possession of northern England. As a result of this situation, the two centuries between the rise of the new dynasty and the beginning of the Hundred Years' War were characterized by a series of wars that ravaged feudal England. Gabriele Esposito covers all these conflicts, following the campaigns of Richard the Lionheart as well as those of his younger brother who was defeated on the continent at the large Battle of Bouvines; the conquest of Wales is analysed in detail, as well as the First Scottish War of Independence that saw William Wallace playing a prominent role. The organisation and equipment of all the troop types taken into account is described in full detail and lavishly illustrated with colour images of reenactors, bringing these forces to life. AUTHOR: Gabriele Esposito is an Italian researcher and a long-time student of military history, whose interests and expertise range widely over various periods. Most of his recent studies have been dedicated to the reconstruction of the organisation, functioning and tactics of the armies across history; in each of his publications there is always some relevant space dedicated to the 'material culture'of the various armies taken into account and - more in particular - to the empirical science known as 'uniformology'. Gabriele is the author of numerous books on armies and uniforms and is a regular contributor to many specialized magazines in Italy, France, Netherlands and UK. His many previous works include Armies of Early Colonial North America 1607-1713; Armies of the Late Roman Empire 284-476; Armies of the Hellenistic States 323 BC to AD30; Armies of Celtic Europe 700 BC-AD 106; Armies of Ancient Greece, circa 500 BC to 338 BC; and The Macedonian Army of Philip II and Alexander the Great 359-323 BC, all published by Pen & Sword since 2018. He lives in southern Italy, near the ancient battlefield of Beneventum. 80 colour illustrations
