De Re Militari

De Re Militari (Concerning Military Affairs), written in the 5th century by Vegetius and translated from the original Latin, is a treatise on warfare in the Roman world and is vital reading for any modern student of the subject as it clearly outlines the methods and practices of the type of warfare waged by the Roman Empire at the height of its power. So influential was Vegetius' book that it was considered as an essential field-guide well into the age of gunpowder. The author covers a broad range of military topics including the selection of personnel suitable for military service, training, logistics and supply, the qualities of leadership and command as well as tactical and strategic matters.
