De Re Militari

"De Re Militari" is a treatise on military strategy and warfare written by the Roman author Vegetius in the 4th or 5th century AD. The title translates to "Concerning Military Matters." It emphasizes the importance of disciplined training, the use of proper tactics, and the organization of military forces to ensure success in battles. Vegetius argued that good soldiers are made through rigorous preparation and education rather than solely through experience. His work influenced military thought for centuries, laying foundational concepts for both Roman and later European military practices.
