Gaius Julius Caesar remains the most famous Roman general of all time. Although he never bore the title, historians since Suetonius have judged him to be, in practice, the very first 'emperor' - after all, no other name in history has been synonymous with a title of imperial rule. Caesar was a towering personality who, for better or worse, changed the history of Rome forever. His unscrupulous ambition was matched only by his genius as a commander and his conquest of Gaul brought Rome its first great territorial expansion outside the Mediterranean world. His charismatic leadership bounded his soldiers to him not only for expeditions 'beyond the edge of the world' - to Britain - but in the subsequent civil war that raised him to ultimate power. What is seldom appreciated, however is that the army he led was as varied and cosmopolitan as those of later centuries, and it is only recently that a wider study of a whole range of evidence has allowed a more precise picture of it to emerge. Drawing on a wide range of new research, the authors examine the armies of Julius Caesar in detail, creating a detailed picture of how they lived and fought.

Preceding and simultaneously with the conquest of England by Duke William, other ambitious and aggressive Norman noblemen (notably the Drengot, De Hauteville and Guiscard families) found it prudent to leave Normandy. At first taking mercenary employment with Lombard rulers then fighting the Byzantine Empire in southern Italy, many of these noblemen achieved great victories, acquired rich lands of their own, and perfected a feudal military system that lasted for 200 years. As news of the rich pickings to be had in the south spread in Normandy, they were joined by many other opportunists - typically, younger sons who could not inherit lands at home. Steadily, these Norman noblemen fought their way to local power, at first in Apulia, then across the Adriatic in Albania, and finally in Muslim Sicily, defeating in the process the armies of Byzantium, the German 'Holy Roman Empire', and Islamic regional rulers. Finally, in 1130, Roger II founded a unified kingdom incorporating southern Italy and Sicily, which lasted until the death of Tancred of Lecce in 1194 - though its legacy long outlasted Norman political rule. This beautifully illustrated title explores not only the Norman armies, but the armies of their opponents, with full-colour plates and expert analysis revealing fascinating details about the fighting men of Normandy, Byzantium, the Arab armies and more.

Civil war in the Western Roman Empire between AD 350-53 had left the frontiers weakly defended, and the major German confederations along the Rhine - the Franks and Alemanni - took advantage of the situation to cross the river, destroy the Roman fortifications along it and occupy parts of Roman Gaul. In 355, the Emperor Constantius appointed his 23-year-old cousin Julian as his Caesar in the provinces of Gaul with command of all troops in the region. Having recaptured the city of Cologne, Julian planned to trap the Alemanni in a pincer movement, but when the larger half of his army was forced into retreat, he was left facing a much larger German force outside the walls of the city of Strasbourg. This new study relates the events of this epic battle as the experience and training of the Roman forces prevailed in the face of overwhelming German numbers.
