German gas attacks were made at night or in the early morning, when the wind was favourable and darkness made it difficult for the defenders to see the gas cloud. [20] [b] Phosgene made the gas cloud more poisonous and the Germans tried to increase the concentration of the gas by discharging it quickly, though this reduced the duration of the ...

Green Cross (Grünkreuz) is a World War I chemical warfare pulmonary agent consisting of chloropicrin (PS, Aquinite, Klop), phosgene (CG, Collongite) and/or trichloromethyl chloroformate (Surpalite, Perstoff). Green Cross is also a generic World War I German marking for artillery shells with pulmonary agents (chemical payload affecting the ...
Phosgene gas had been released by the Canadians prior to going "over the top". The gas release had alerted the defenders that an attack was forthcoming, and the alarm was raised. German shells began a steady fire on the Canadian lines, some hitting canisters of Chlorine gas that had been brought forward but not deployed.
Phosgene was up to six times as potent than chlorine and did not suggest any urgent symptoms that was associated with the coughing and discomfort that chlorine did. Psychological impacts of the gas had resulted in unexplained anxiety attacks which would cause men to tear off their gas masks to breathe correctly exposing them to the gas. [3]
