Chem & Bio in the ACW was possible and proposed
Ah, the potential for chemical as well as biological warfare in the ACW was fully present and proposed often.
The following were known at the dawn of the war and were available in varying quantities: Chlorine, Hydrogen Cyanide, Cyanogen Chloride, Phosgene, Mustard Agent, Cacodyl and Chloropricrin. Some were more difficult to produce in quantity or et al, some of the chemical’s property lay largely unknown or neglect but all were discovered by 1861.
The Chemical Industry was less developed in the South but present for agricultural and explosive manufacturing. Protective Masks were also being patented in the US in the 1850s.
Agent delivery systems were proposed by both sides from: dropping poison gas from a balloon, Chlorine Shells, a Chloroform Spraying “Fire” Engine, generation of a cloud of Hydrochloric/Sulfuric Acid, a Glass Grenade filled with Cacodyl, Suffocating Smoke Cartridge and a Stink Shell.
