Sauterelle The Arbalète sauterelle type A, or simply Sauterelle (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.
New Zealand Tunnelling Company The New Zealand Tunnelling Company (also "New Zealand Engineers Tunnelling Company") was a tunnel warfare unit of the Royal New Zealand Electrical and Mechanical Engineers during World War I which specialised in sapping and mining. The tunnelling companies were occupied in offensive and defensive mining involving the placing and maintaining of mines under enemy lines, as well as other underground work such as the construction of deep dugouts for troop accommodation, the digging of subways, saps (a narrow trench dug to approach enemy trenches), cable trenches and underground chambers for signals and medical services. The unit is particularly known for its role at Carrière Wellington and during the Battle of Arras.
