Sir Charles Oman brings medieval warfare to life in this comprehensive work of military history. He traces the evolution of weaponry, strategy and tactics from the end of the Byzantine Empire to the final battlefield dominance of the armored knight. Many conflicts are discussed in depth, including the Viking invasions, the Crusades, the Hundred Years War, and the English wars against the Scottish. Additional chapters cover advances in siege warfare and defenses, and the varied recruitment and organization methods of the many different armies.
