So is the story of blankets that had smallpox in them given to the Indians to try and wipe them out also false?
For it to be true, the infected blankets would have to have been handled exclusively by smallpox survivors.
That was the British later against Pontiac, Captain Simeon Ecuyer. But Sir Jeffery Amherst also tossed the idea around as a useful weapon under the guise of “inoculation”.
most likely ... unless you believe Howard Zinn ...
That was certainly true in the US in the 19th Century. In Mexico in the 16th Century there were terrible plagues that killed millions of Indians. On the other hand Europeans learned the “pleasures” of Syphilis.
