A superb analysis of the military power that underpinned Augustus’ rise to power, his conquests, and his ability to sustain his rule. Powell’s achievement is to demonstrate just how much Augustus deserved his name of ‘Imperator’.'

– Tom Holland, presenter of BBC Radio 4 Making History. Author of Dynasty: The Rise and Fall of the House of Caesar.

'In this book, Powell meticulously details and analyzes the composition, deployment, and actions of this army and provides a much needed resource of information that has no parallel in astute comprehensiveness. His superb treatment shows Imperator Caesar Augustus in action and helps us understand the military Augustus and his times more clearly.'

– Karl Galinsky, Floyd A. Cailloux Centennial Professor of Classics, University of Texas at Austin. Author of Augustus: Introduction to the Life of an Emperor.

'Lindsay Powell provides us with valuable insights into an under-appreciated aspect of Augustus' reign, and does so in his usual highly competent and readable style.'

– Philip Matyszak Author of The Sons of Caesar: Imperial Rome's First Dynasty.

'Concise yet insightful, well-written and page-turning, this is a 'must buy' for every fan of ancient history. Powell is rapidly establishing himself as one of the leading authors of Roman nonfiction.'
