Came across this one quite by accident. From the wiki in part WHY the German did not resort to chemical weapons during the Second World War [WW2]:

"the Allies knew the Germans had quantities of Gas Blau available for use in the defense of the Atlantic Wall. The use of nerve gas on the Normandy beachhead would have seriously impeded the Allies and possibly caused the invasion to fail altogether. [that question being asked] 'Why was nerve gas not used in Normandy?' [as asked of] Hermann Göring . . . Göring answered that the reason gas was not used had to do with horses. The Wehrmacht was dependent upon horse-drawn transport to move supplies to their combat units, and had never been able to devise a gas mask horses could tolerate; the versions they developed would not pass enough pure air to allow the horses to pull a cart. Thus, gas was of no use to the German Army under most conditions".

Comments:

* Gas Blau not a toxic chemical warfare agent? Used for inflating balloons and dirigibles and not lethal on the battlefield?

* Germany prior to what is commonly perceived during the Second World War highly dependent on horses as prime-movers.

* Germany possessing nerve agent prior to D-Day. ALLIED GAS MASK FILTERS AT THAT TIME  INEFFECTIVE AGAINST NERVE AGENT!

* My understanding has always been that the Germans also believed the allies had nerve gas. The allies did not have nerve gas, but the German did believe so. That threat of retaliation in kind enough to dissuade the German chemical weapons. Perception is reality more so than reality is fact?

* Allies when landing at Normandy having issued to their troops the antidote for bio toxin poisoning. Allied troop uniforms also treated with the chemical CC-2. Further protection against poison gas attack of the blister agent variety. CC-2 also resulting in the troop having a terrible odor and stink most foul about him for a prolonged period.

To war with horse but no gas mask for horse and no poison gas? Can it be so?
