The Arbalète sauterelle type A, or simply Sauterelle ([so.tʁɛl] French for grasshopper), was a bomb-throwing crossbow used by French and British forces on the Western Front during World War I. It was designed to throw a hand grenade in a high trajectory into enemy trenches. It was initially dismissed by the French Army but General Henri Berthelot thought it had practical value.^[1]

It was lighter and more portable than the Leach Trench Catapult, but less powerful. It weighed 24 kg (53 lb) and could throw an F1 grenade or Mills bomb 110–140 m (120–150 yd).^[2]

The Sauterelle replaced the Leach Catapult in British service until they were replaced in 1916 by the 2 inch Medium Trench Mortar and Stokes mortar.^[3]
