When Germany Invented Hell in a Can But Forgot to Bring Backup: The Day Soldiers Peed on Their Faces to Survive

On April 22, 1915, the Second Battle of Ypres became the site of humanity's first large-scale gas attack, when German forces released 168 tons of chlorine gas across a four-mile front against French colonial troops. The yellowish-green cloud drifted toward Allied lines with all the subtlety of death itself taking a leisurely stroll. The French Algerian and Territorial divisions, who had the misfortune of being directly in the path, did what any rational person would do when confronted with a mysterious poisonous fog: they panicked and fled, leaving a gaping hole in the Allied lines. One cannot fault their survival instincts. What makes this particularly noteworthy beyond the obvious horror is that the Germans, despite having just invented a terrifying new form of warfare, were apparently so skeptical of their own weapon that they failed to bring sufficient reserves to exploit the breakthrough. It's rather like spending years developing a revolutionary can opener, successfully opening the can, and then wandering off because you didn't really believe there'd be food inside. Canadian troops, positioned adjacent to the collapsing French lines, found themselves exposed on their flank. In what can only be described as battlefield improvisation at its finest, they urinated on handkerchiefs and held them over their faces—the ammonia in urine partially neutralizing the chlorine. They then proceeded to hold their position for two days, presumably while breathing through their own waste products and contemplating the increasingly absurd nature of modern warfare. This marked the permanent introduction of chemical weapons to World War I, ensuring that gas masks would become this generation's must-have accessory.
