Gas
The German army were the first to use chlorine gas at the battle of Ypres in 1915. Chlorine gas causes a burning sensation in the throat and chest pains. Death is painful - you suffocate! The problem with chlorine gas is that the weather must be right. If the wind is in the wrong direction it could end up killing your own troops rather than the enemy.
Mustard gas was the most deadly weapon used. It was fired into the trenches in shells. It is colourless and takes 12 hours to take effect. Effects include: blistering skin, vomiting, sore eyes, internal and external bleeding. Death can take up to 5 weeks.
"[The] vapor settled to the ground like a swamp mist and drifted toward the French trenches on a brisk wind. Its effect on the French was a violent nausea and faintness, followed by an utter collapse. It is believed that the Germans, who charged in behind the vapor, met no resistance at all, the French at their front being virtually paralyzed." as reported in the New York Tribune, April 27, 1915.
