I do not believe that there is any documentation for the claim that Lord Amherst implemented a scheme to infect Native Americans with small pox. The only reference I have seen to the small pox scheme is Amherst's letter (quoted by Francis Parkman in his history of Pontiac's rebellion) to the effect that the colonials should "find a way" to infect the indians with small pox. Parkman states that there is no direct evidence that the scheme was implemented. This claim, like that concerning the plains indians, may well be false, notwithstanding the fact that it is presented as fact in current history texts.
