The Leach Trench Catapult (sometimes called a Leach-Gamage 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 calapault it was effectively combination crossbow and slingshot.
