1763–64: Britain wages biological warfare with smallpox
The British give smallpox-contaminated blankets to Shawnee and Lenape (Delaware) communities—an action sanctioned by the British officers Sir Jeffery Amherst and his replacement, General Thomas Gage.
“Out of our regard to them … we gave them two Blankets and an Handkerchief out of the Small Pox Hospital. I hope it will have the desired effect.” —An eyewitness, quoted in Elizabeth A. Fenn, Pox Americana: The Great Smallpox Epidemic of 1775–81, 2001
