I should add that later stories blaming the US Army for giving out those blankets during our Indian wars were found to be BS.
The disgraceful accusation that U.S. Army used smallpox infested blankets in the Indians wars, was made by Ward Churchill whose academic misconducts included charges of plagiarism, fabrication, and falsification at the University of Colorado at Boulder, where Churchill was a professor. On May 16, 2006, the investigative committee released its findings that Churchill had been "disrespectful of Indian oral traditions, and the University's Standing Committee on Research Misconduct voted that Churchill should be dismissed.
Americans never gave smallpox blankets to any Indians anywhere at anytime. Not the government, not the Army, not anyone. So we are absolved on that one. The incident in question occurred in 1763, before there even was a USA, before there even were Americans. And American colonists (pre-Americans) didnt do it either. It was the British that done the deed.
