While World War II is well-known as the beginning of the age of atomic weapons, World War I is lesser-known as dawn of the age of chemical weapons. The 1914-1918 conflict saw development and large-scale production of mustard gas, lewisite, and other chemical agents specially designed and packaged for use in armed conflict. With the armistice ending the War to End All Wars, large quantities of this material was left with no place to go. The technology to safely destroy these chemical weapons did not exist and public concern over its existence was largely nil. Without giving the matter much thought, the victorious Allies took much of the surplus chemical weapons out to sea and dumped it overboard.
