Dr Simon Elliott describes eight of the greatest, most decisive of the Roman Empire of the first to third centuries. The list includes battles fought from the highlands of Scotland and the forests of Germany to the deserts of the Middle East. They show how the vaunted Roman legions adapted to extremes of terrain and climate as well as a wide array of very different foes, from the wild Caledonian tribes to the sophisticated, combined-arms armies of Sassanid Persia with their war elephants and superb cavalry. Some of the battles even pit the Roman legions against their own kind in brutal civil wars.After an introductory chapter on the Imperial Roman army, detailing its organization, equipment, tactics and doctrine, the author moves on to describing each battle in detail. He sets the strategic context and background of the chosen engagement before analysing the size and composition of the opposing forces, also detailing the nature of the enemy faced. The manoeuvres leading up to the battle are described, followed by deployment and the course of the fighting itself. Finally, the aftermath and implications of the battles outcome are assessed. The well-researched and engaging text is supported by clear maps.
