I have just read a book entitled 'Chemical Soldiers' by Donald Richter. It is the story of British gas warfare in WW1.
It describes the various methods of delivering poison gas to the enemy trenches. One of the methods was to load narrow gauge wagons with gas cylinders fitted with a detonator head to release the gas. When a favourable wind was forecast these wagons were taken right up to the front line trenches in the dark and and British troops pulled back behind the danger zone and then the gas was released.
As I model the French narrow gauge railway only, I would like to know if the French followed a similar practice.
