when was the first time poison gas was used in ww1
Chemical weapons in World War I The earliest military uses of chemicals were tear-inducing irritants rather than fatal or disabling poisons. During World War I, the French army was the first to employ gas, using 26 mm grenades filled with tear gas (ethyl bromoacetate) in August 1914. The small quantities of gas delivered, roughly 19 cm³ per cartridge, were not even detected by the Germans. The stocks were rapidly consumed and by November a new order was placed by the French military. As bromine was scarce among the Entente allies, the active ingredient was changed to chloroacetone.[7]
American Revolution Support for the conflict had never been strong in Britain, where many sympathized with the Americans, but now it reached a new low.[72] King George III personally wanted to fight on, but his supporters lost control of Parliament and no further major land offensives were launched in the American Theater.[65][73]
Aerial warfare Airplanes were put to use for war starting in 1911, initially for aerial reconnaissance, and then for aerial combat to shoot down the recon planes. Aircraft continued to carry out these roles during World War I, but the use of planes and zeppelins for strategic bombing emerged in World War I.
World War I The term "First World War" was first used in September 1914 by the German biologist and philosopher Ernst Haeckel, who claimed that "there is no doubt that the course and character of the feared 'European War'Â ... will become the first world war in the full sense of the word,"[20] citing a wire service report in The Indianapolis Star on 20 September 1914. After the onset of the Second World War in 1939, the terms World War I or the First World War became standard, with British and Canadian historians favouring the First World War, and Americans World War I.[21]
