Calling all pumpkin chuckers, wannabe marauders, and tinkerers of all ages! Flinging things and playing at defending your own castle has never been more fun. Whether playing at defending their own castle or simply chucking pumpkins over a fence, wannabe marauders and tinkerers will become fast acquainted with Ludgar the War Wolf, Ill Neighbor, Cabulus, and the Wild Donkey—ancient artillery devices known commonly as catapults. Updated and improved instructions and diagrams illustrate how to build 10 authentic working model catapults, including an early Greek ballista, a Roman onager, and the apex of catapult technology, the English trebuchet. Additional projects include learning how to lash and make rope and how to construct and use a hand sling and a staff sling. Building these simple yet sophisticated machines introduces fundamentals of math and physics using levers, force, torsion, tension, and traction. The colorful history of siege warfare is explored through the stories of Alexander the Great and his battle of Tyre; Saladin, Richard the Lionheart, and the Third Crusade; pirate-turned-soldier Jon Crabbe and his ship-mounted catapults; and Edward I of England and his battle against the Scots at Stirling Castle. For the legions of Tolkien fans, budding backyard warriors, and engineering wizards, this book is a must-have.

During World War I, the navies of the opposing forces discovered the value of aerial reconnaissance and many experiments were made to allow larger warships to carry one or sometimes two aircraft aboard. In the early days these were float planes that were lowered by crane into the sea and then lifted back aboard upon their return. This was a lengthy affair and when a speedy departure was necessary, time was of the essence. A new system was devised so that a powerful catapult system and a short ramp could, with the added speed of the ship, get an aircraft airborne in a fraction of the time previously required. Thus was born a highly specialised type of aircraft. This book includes all the major designs that went to war in the First and Second World Wars and includes aircraft used by all the combatants. It looks at how the aircraft evolved and how the warships were modified to accommodate the aircraft and the catapult system. The use of these fixed-wing aircraft was abandoned when the invention of the helicopter was made in the early post WW II years.
