In 53 BC, Roman and Parthian forces collided in a confrontation that would reshape the geopolitical map and establish a frontier between East and West that would endure for the next 700 years. From the initial clash at Carrhae through to the battle of Nisibis more than 250 years later, Roman and Parthian forces fought a series of bloody campaigns for mastery of the Fertile Crescent. As Roman forces thrust ever deeper into the East, they encountered a civilization unlike any they had crossed swords with before. Originating in the steppes of Central Asia, the Parthians ruled a federated state stretching from the Euphrates to the Indus. Although Rome's legions were masters of the battlefield in the Mediterranean, the Parthians refused to fight by the rules as Rome understood them. Harnessing the power of the composite bow and their superior manoeuvrability, the Parthians' mode of warfare focused exclusively on the horse. They inflicted a bloody defeat on the legions at Carrhae and launched their own invasion of Roman territory, countered only with great difficulty by Rome's surviving forces. The Parthians were eventually thrown out, but neither side could sustain a permanent ascendancy over the other and the conflict continued. Packed with stunning artwork, including battlescenes, maps and photographs, this title examines the conflict through the lens of three key battles, revealing a clash between two armies alien to each other not only in culture but also in their radical approaches to warfare.

Caesar's war machine clashes with the fearsome tribes of Gaul, forever changing the character of the region and laying the groundwork for the rise of the Roman Empire. In the manner of many Roman generals, Caesar would write his domestic political ambitions in the blood and treasure of foreign lands. His governorship of Cisalpine Gaul gave him the opportunity to demonstrate the greatness of his character to the people of Rome through the subjugation of those outside Rome's borders. The fact that the main account of the subsequent wars in Gaul was written by Caesar himself – by far the most detailed history of the subject, with new reports issued annually for the eager audience at home –is no accident. The Roman Army of the late Republic had long been in the process of structural and change, moving towards the all-volunteer permanent standing force that would for centuries be the bulwark of the coming Empire. Well-armed and armored, this professional army was trained to operate within self-supporting legions, with auxiliaries employed in roles the legions lacked such as light troops or cavalry. The Roman legions were in many ways a modern force, with formations designed around tactical goals and held together by discipline, training and common purpose. The armies fielded by the tribes of Gaul were for the most part lightly armed and armored, with fine cavalry and a well-deserved reputation for ferocity. As might be expected from a region made up of different tribes with a range of needs and interests, there was no consensus on how to make war, though when large armies were gathered it was usually with the express purpose of bringing the enemy to heel in a pitched battle. For most Gauls – and certainly the military elites of the tribes – battle was an opportunity to prove their personal courage and skill, raising their status in the eyes of friends and foes alike. Fully illustrated, this study investigates the Roman and Gallic forces pitched into combat in three battles: Bibracte (58 BC), Sabis (57 BC) and Gergovia/Alesia (52 BC). Although charismatic Gallic leaders did rise up – notably Dumnorix of the Aedui and later Vercingetorix of the Arverni – and proved to be men capable of bringing together forces that had the prospect of checking Caesar's ambitions in the bloodiest of ways, it would not be enough. For Caesar his war against the Gauls provided him with enormous power and the springboard he needed to make Rome his own, though his many domestic enemies would ensure that he did not long enjoy his success.

Ravaged by civil war and pressure from the Huns to the east, in late summer AD 376 the Gothic tribe of the Theruingi – up to 200,000 people under their leader Fritigern – gathered on the northern bank of the River Danube and asked the Eastern Roman emperor, Valens, for asylum within the empire. After agreeing to convert to Arian Christianity and enrol in the Roman Army, the Goths were allowed to cross the Danube and settle in the province of Thrace. Far more people crossed the Danube than the Romans expected, however, and with winter approaching, the local Roman commander, Lupicinus, lacked the resources to feed the newcomers and did not possess sufficient troops to control them. Treated poorly and running out of food, the Goths very quickly lost faith in the Roman promises. Meanwhile, other Gothic tribes also sought permission to cross the Danube. The Greuthungi were refused permission, but soon learned that local Roman garrisons had been depleted to supervise the march of the Theruingi to the town of Marcianopolis, close to the eastern shore of the Black Sea. Taking advantage of this, the Greuthungi also entered Roman territory. Camping outside Marcianopolis, Lupicinus denied the Goths access to the town's food stores, provoking the Theruingi to begin skirmishing with the Roman troops. Fritigern convinced Lupicinus to let the Gothic leaders go and calm their people, but they did nothing to quell the warlike temper of his warriors. Lupicinus summoned troops to him, but in late 376 these Roman forces were defeated – the first of several defeats for the Romans that would culminate in the fateful battle of Adrianople in August 378, at which Roman forces led by the emperor himself confronted the Gothic host. The aftermath and repercussions of Adrianople have been much debated, but historians agree that it marks a decisive moment in the history of the Roman world. This fully illustrated book investigates the fighting men of both sides who clashed at the battles of Marcianopolis, Ad Salices and Adrianople, as the fate of the Western Roman Empire hung in the balance.

Between AD 161 and 244 the Roman legions were involved in wars and battles on a scale not seen since the late Republic. Legions were destroyed in battle, disbanded for mutiny and rebellion and formed to wage wars of conquest and defence. This volume explores the experience of the imperial legionary, concentrating on Legio II Parthica. Raised by the emperor Septimus Severus in AD 193/4, it was based at Albanum near Rome and as the emperor's personal legion, became one of the most important units in the empire.

In the years between 31 BC and AD 500 the Romans carved out a mighty empire stretching from Britain to the deserts of North Africa. The men who spearheaded this expansion were the centurions, the tough, professional warriors who led from the front, exerted savage discipline and provided a role model for the legionaries under their command. This book, the second volume of a two-part study, reveals the appearance, weaponry, role and impact of these legendary soldiers during the five centuries that saw the Roman Empire reach its greatest geographical extent under Trajan and Hadrian, only to experience a long decline in the West in the face of sustained pressure from its 'barbarian' neighbours. Featuring spectacular full-colour artwork, written by an authority on the army of the Caesars and informed by a wide range of sculptural, written and pictorial evidence from right across the Roman world, this book overturns established wisdom and sheds new light on Rome's most famous soldiers during the best-known era in its history.
