Diocletian and Constantine were the greatest of the Late Roman emperors, and their era marks the climax of the legionary system. Under Constantine's successors the legions were reduced in size and increasingly sidelined in favour of new units of elite auxilia, but between AD 284 and 337 the legions reigned supreme. The legionaries defeated all-comers and spearheaded a stunning Roman revival that humbled the Persian Empire and reduced the mighty Goths and Sarmatians to the status of vassals. This title details the equipment, background, training and combat experience of the men from all parts of the empire who made up the backbone of Rome's legions in this pivotal period.

The Roman centurion, holding the legionaries steady before the barbarian horde and then leading them forward to victory, was the heroic exemplar of the Roman world. This was thanks to the Marian reforms, which saw the centurion, although inferior in military rank and social class, superseding the tribune as the legion's most important officer. This period of reform in the Roman Army is often overlooked, but the invincible armies that Julius Caesar led into Gaul were the refined products of 50 years of military reforms. Using specially commissioned artwork and detailed battle reports, this new study examines the Roman legionary soldier at this crucial time in the history of the Roman Republic from its domination by Marius and Sulla to the beginning of the rise of Julius Caesar.

Between the 3rd and 6th centuries AD the traditional legions of heavy infantry were whittled away and eventually replaced by a force of various arms and nationalities dominated by cavalry and supported by missile troops. However, in spite of this trend towards cavalry, the pedes remained the backbone of the Roman army until well into the 5th century. This book details a warrior who was very different from the legionary who preceded him; perhaps he was not as well disciplined, but in many ways he was more flexible – ready for deployment to trouble spots, and for fighting both as a skirmisher and a heavy infantryman.

An illustrated guide to the organization, structure, equipment, weapons, combat history, and tactics of the Late Roman military forces. This guide to the Late Roman Army focusses on the dramatic and crucial period that started with the accession of Diocletian and ended with the definitive fall of the Western Roman Empire. This was a turbulent period during which the Roman state and its armed forces changed. Gabriele Esposito challenges many stereotypes and misconceptions regarding the Late Roman Army; for example, he argues that the Roman military machine remained a reliable and efficient one until the very last decades of the Western Empire. The author describes the organization, structure, equipment, weapons, combat history and tactics of Late Roman military forces. The comitatenses (field armies), limitanei (frontier units), foederati (allied soldiers), bucellarii (mercenaries), scholae palatinae (mounted bodyguards), protectores (personal guards) and many other kinds of troops are covered. The book is lavishly illustrated in color, including the shield devices from the Notitia Dignitatum. The origins and causes for the final military fall of the Empire are discussed in detail, as well as the influence of the “barbarian” peoples on the Roman Army. Praise for Armies of the Late Roman Empire, AD 284–476 “An excellent introduction to the subject for the novice, and seasoned students of the subject may find it of use as well.” —The NYMAS Review “This beautifully illustrated book depicts the very different arms and armour of the late Roman Empire as Roman soldiers adapted to the challenges of the rising barbarian armies . . . Very Highly Recommended.” —Firetrench “Superbly well-illustrated . . . historians, re-enactors and war gamers will find invaluable to understanding and picturing the Roman forces.” —Hoplite Association

Between AD 69 and 161 the composition of the Roman legions was transformed. Italians were almost entirely replaced by provincial recruits, men for whom Latin was at best a second language, and yet the 'Roman-ness' of these Germans, Pannonians, Spaniards, Africans and Syrians, fostered in isolated fortresses on the frontiers, was incredibly strong. They were highly competitive, jealous of their honour, and driven by the need to maintain and enhance their reputations for virtus, that is manly courage and excellence. The warfare of the period, from the huge legion versus legion confrontations in the Civil War of AD 69, through the campaigns of conquest in Germany, Dacia and Britain, to the defence of the frontiers of Africa and Cappadocia and the savage quelling of internal revolts, gave ample opportunity for virtus-enhancing activity. The classic battle formation that had baffled Pyrrhus and conquered Hannibal was revived. Heroic centurions continued to lead from the front, and common legionaries vied with them in displays of valour. The legions of the era may have been provincial but they were definitely Roman in organisation and ethos.

The twilight of the Roman Empire saw a revolution in the way war was waged. The drilled infantryman, who had been the mainstay of Mediterranean armies since the days of the Greek hoplite, was gradually replaced by the mounted warrior. This change did not take place overnight, and in the 3rd and 4th centuries the role of the cavalryman was primarily to support the infantry. However, by the time of the 6th century, the situation had been completely reversed. Late Roman Cavalryman gives a full account of the changing experience of the mounted soldiers who defended Rome's withering western empire.
