Defending Your Castle: Build Catapults, Crossbows, Moats, Bulletproof Shields, and More Defensive Devices to Fend Off the Invading Hordes As the saying goes, "A man's home is his castle," but can it withstand an attack by Attila the Hun, Ragnar and the Vikings, Alexander the Great, Genghis Khan, or Tamerlane and the Tartars? In his fascinating book, Backyard Ballistics author William Gurstelle poses this question to modern-day garage warriors and provides them with the tools to defend their castles against these invading hordes. Each chapter introduces a new bad actor in the history of warfare, details their conquests, and features weapons and fortifications to defend against them and their minions. The book begins with a brief overview of the evolution of technology and the importance of understanding the process of technological development as the basis for human survival. It emphasizes the need to develop a personal paradigm for perceiving the technological process of developing modern knowledge, which is crucial for the survival of humanity and the unification of people in a warring state. The text is written in a simplified and accessible format, making it easy to understand for readers of all backgrounds. Chapter 1: The Invaders The first chapter introduces the reader to Attila the Hun, who conquered much of Europe and Asia during the 5th century AD. Gurstelle explains how Attila's army was known for its brutality and destruction, and how building a catapult can help defend against such invaders.
