Mustard Gas Usage in World War I

Mustard gas was a chemical weapon used extensively in World War I, first introduced by Germany in 1917. This yellowish gas caused severe blistering, respiratory damage, and long-term health issues, making it particularly horrific. Unlike bullets, it lingered in trenches and on battlefields, affecting not only soldiers but also civilians. The psychological impact was profound, as soldiers faced an invisible enemy. Its deployment marked a significant shift in warfare, leading to international efforts in later years to ban chemical weapons due to the inhumane suffering it caused.
