Many soldiers went to war thinking it would be an adventure and they would come back as heroes. This picture clearly portrays the horrors of world war one, it was not glorious at all. This picture shows that in World War One  they needed protection from chlorine gas. Chlorine gas was a weapon used by the Germans. It would destroy the respiratory organs of its victims and this led to a slow death of asphyxiation. Doctors could not find a way to cure it. Instead they came up with gas masks to prevent inhaling it.
