Leach trench catapult

Catapult

The Leach trench catapult was a bomb-throwing catapult used by the British Army on the Western Front during World War I. It was designed to throw a 2 lb (0.91 kg) projectile in a high trajectory into enemy trenches. Although called a catapult, it was effectively a combination crossbow and slingshot. It was invented by Claude Pemberton Leach as an answer to the German Wurfmaschine, a spring-powered device for propelling a hand grenade about 200 m (220 yd).
