The author also explains the science behind many projects, making this a valuable supplement to your history or science curricula or an appealing father-son project book as they strive to defend their home at all costs against the invading hordes, and learn just a bit more about ourselves, our history and the sciences! 168 pgs, sc. ~ Deanne
Your home is your castle, but could it withstand an attack by Attila and the Huns, Ragnar and the Vikings, Alexander and the Greeks, Genghis Khan and the Mongols, or Tamerlane and the Tartars? Engineer William Gurstelle, author of the bestselling Backyard Ballistics, poses this fascinating question to modern-day garage warriors and shows how to build an arsenal of ancient artillery and fortifications aimed at withstanding these invading hordes. Each chapter introduces new bad actors in the history of warfare, details their conquests, and features weapons and fortifications to defend against themculminating, by the end of the book, in a fully fortified home. Clear step-by-step instructions, diagrams, and photographs explain how to build a dozen projects from table-top models of the Cheval-de-frise, Da Vinci's Catapult, and Alexander's Tortoise to the fullsize working Carpini's Crossbow, Hour-Glass Watchtower, and Palisade Wall.
