This book provides a complete and detailed analysis of the organisation and equipment of the Macedonian army built by Philip II and later employed to world-changing effect by his son, Alexander III (the Great). This work explains how Philip took the traditional forces of Macedon and reformed them into the most modern and sophisticated combined-arms force in the Mediterranean world. Not only the formidable pike phalanx and the hard-charging Companion cavalry, but also the less famous components, such as light and cavalry types, are described in detail. The tactics employed in the great battles that won the largest empire the world had seen are analysed. With numerous colour photos showing replica weapons and equipment in use, this is a vivid, detailed and accessible study of the army that made Alexander great. 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 and Armies of Ancient Greece, circa 500 BC to 338 BC, all published by Pen & Sword since 2018. He lives in southern Italy, near the ancient battlefield of Beneventum. 90 colour illustrations
