Gases of WWI
Gases used in WWI include tear gas, chlorine, and mustard gas. The most lethal of these was mustard gas. it would eat through facial features and caused blisters throughout the body.
Tear gas was used as a disabling gas rather than killing. It was used in WWI to induce tears into the enemy's eyes. The French were first to use this chemical weapon in WWI, but the Germans caught on.
Misunderstanding of the Origin of Chemical Warfare
Although most people think Germans were first to use chemical warfare, it was indeed the French. They released the first tear gas bombs, but the Germans took it to a whole new level. In 1914, they released a bomb to the French which caused a fit of sneezing that seemed everlasting. In 1915, they began to also use tear gas.
In April of 1915, chemical warfare was changed. At the start of the Second Battle of Ypres, poison gas known as chlorine was released. The French and Algerian troops were marching into German lands and noticed a yellowish, greenish cloud coming at them. The French thought that the Germans put this there to hide their troops to where they could not see them, but they were wrong. Within seconds of inhaling this poisonous gas, victims' lungs and organs were taken over and a loss of breathing was experienced.
In 1917, the Germans unmasked a new and even more powerful poisonous gas. It was used against the Russians and was contained in artillery shells. They called it mustard gas. Without odor, it caused internal as well as external blisters many hours after the attack. Since you never knew when this gas was in the air, it made it hard to be protected. All of the Allies began using this gas as a weapon throughout the war.
loss of effectiveness
As the surprise factor of these gases were lost, it became much less effective of a weapon. The casualty rate from these gases went significantly down because of the lack of usage after mid-1915.
CASUALTIES FROM GAS- THE NUMBERS
Silent and Deadly - GAS WARFARE IN WORLD WAR 1
Chemical Warfare did not stop here. Still today, it is used in battles and wars around the country, most identified with ISIS. Poison gases play a large role in warfare and will continue too because of the simplicity and easiness of the weapon.
