Relying on a variety of literary, documentary and archaeological sources, this work explores the Roman military supply system from the Punic Wars to the end of the Principate. Each chapter is devoted to a different aspect of logistics: supply needs and rations; packs, trains and military servants; foraging and requisition; supply lines; sources of supply; administration; and the impact of logistics on Roman warfare.As a whole the book traces the development of the Roman logistics into a highly sophisticated supply system - a vital element in the success of Roman arms. In addition, it makes a critical study of important technical questions of Roman logistics, such as the size of the soldier's grain ration, the function of military servants, and the changes in logistical management under the Republic and Empire.
