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.
