During World War II, German chemists developed the deadly gas known as Sarin. However, they did not use it on the battlefield because of Adolf Hitler’s hesitation.
By the end of World War II, Germany had produced some 12,000 tons of the deadly chemical compound, enough to kill millions of people. From early in the conflict, high-level military officers pressed Hitler to use sarin against their adversaries to shorten the war. But despite such pressure, Hitler declined to employ it as a chemical weapon against the Allied Powers.
