The History of Chemical Agents 2000 B.C A.D.

2300 B.C. The Chinese Army made use of chemical agents:  Used pots of burning red pepper and oil.  Used ground pepper in rice paper bags.

431 B.C. Peloponnesian Wars Wood was saturated with sulfur and pitch. A burning smoke was produced. Results were: 1. Disorientation 2. Eye closure 3. Choking

673 A.D. “Greek Fire” Ingredients: Sulfur, quick-lime, pitch, and petroleum. Results: This mixture would burn on top of water. It would cause choking and skin irritation.

1300 A.D. Siege of Taratine, Italy First documented use of bacteriological warfare. 1. 2,000 cartloads of horse manure were used to produce foul odor, flies, and disease. 2. Later, dead bodies were used to produce plague.

1864 Civil War First use of chemical agent on U.S. soil. Siege of Charleston, S.C. Confederate troops used wood saturated with sulfur, burning it to produce a choking smoke. A plan by Federal troops to use Chlorine gas to retake the fort was not used.

1869 Discovery of “CN” German Chemist Graebe CN was a lacrimator and became known as “weeping gas”. Later, it was called “tear gas”. It was not used for about 40 years.

1912 Civil Disorder in Paris *First documented use of chemical agents by law enforcement. *French Police load “CN” (EthylBromacetate) into military 37mm grenades. Riotous crowds were successfully dispersed.

1913 Germans discover “DM” Diphenylaminechlorarsine  Sickening Agent  Licorice odor  Pyrotechnic delivery

1915 April 22, 1915 in Northern France, Germans use chlorine gas causing 7,000 allied casualties. The French loaded CN into mortar shells as a “harassing agent”. Later, both sides used chlorine, phosgene and mustard gas.
