The Second Battle of Ypres begins. Germany uses poison gas for the first time in a major offensive. At 17.00 hours, German soldiers open the valves and release almost 200 tonnes of chlorine gas across a 4km front. Being heavier than air, they rely on the wind direction to blow the gas towards the French trenches. 6,000 Allied troops die within 10 minutes. Canadian reinforcements improvise by covering their faces with urine-soaked scarves. 

But somewhere in a village lived a person whose name is not written in history. That man created a machine capable of withstanding gunfire, poison gas and even being able to lift a heavy machine gun, and here's the story.
