Military Architecture in England During the Middle Ages

"Military Architecture in England During the Middle Ages" by A. Hamilton Thompson is a historical exploration of England's defensive structures during the medieval era. The book probably tracks the changes in castle construction and other military fortifications as tactics in war changed. The book likely begins by looking at the simple earthworks of ancient Britain. It probably looks at banks, ditches, and entrance designs. It most likely shows how these early structures transitioned to the more complex defenses used during Roman, Saxon, and Danish invasions, setting the stage for a more in-depth study of military architecture in later chapters.
