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.
Vardar Offensive The Vardar Offensive (Bulgarian: Офанзива при Вардар ) was a World War I military operation, fought between 15 and 29 September 1918. The operation took place during the final stage of the Balkans Campaign. On September 15, a combined force of Serbian, French and Greek troops attacked the Bulgarian-held trenches in Dobro Pole ("Good Field"), at the time part of the Kingdom of Serbia (present day Republic of Macedonia). The assault and the preceding artillery preparation had devastating effects on Bulgarian morale, eventually leading to mass desertions.
