What did posion gas do in world war 1?

Answer 1

Poison gas was used as a weapon during World War I, causing widespread injury and death among soldiers. It introduced a new level of terror on the battlefield, with gases like chlorine, phosgene, and mustard gas inflicting severe respiratory damage and burns. The unpredictable nature of wind often affected both attackers and defenders, leading to chaotic and devastating conditions. Despite its psychological impact, the use of poison gas was later condemned and became a significant factor in the development of international chemical weapons bans.
