This German attack failed because of the very cold temperature on the Polish front which stifled gas spreading and effects. The escalation of the chemical war is launched in 1915 with the use on East front of gas shells on January 31th. For its part, Germany used its chemical industry to develop weapons with chlorine. WW1 chemical weaponsįrom the beginning of the First World War, chemical weapons were used: in August 1914, the French army used new grenades filled with tear gas (actually created for the Parisian police).

Thus the conception of an efficient WW1 gas mask was extremely important. Despite the signature of the Hague Convention in 18, France, Germany and many other countries did not stop their research and did not give up on using these weapons during the First World War. In the early 20th century, the German Empire chemical industry was very developed and this country quickly became a world leader for chemistry and could swiftly develop the chemical weapons that evolved all along the war. Before WW1 started, France also created a suffocating grenade. Yet, at that time, chemical weapons are also being developed and shells filled with sulfur oxide, picric acid or chlorine were used by headquarters. At the end of 19th century, wars – particularly the Crimean War and the American Civil War – privileged production of artillery weapons such as canons. Historians report that poisons (rye ergot, hellebore root, curare) were used in most of wars and military conflicts that occurred through the ages. Since the antiquity, chemical – and biological – weapons have been used in combat.
