Oh look, you are spewing that particular myth. Having actually looked into it, there isn’t actually any evidence that the words of Jeffrst Amherst were actually acted on.
You're correct, not because there is no evidence, but because Baron Amherst wasn't involved, it was Captain Simeon Ecuyer at Fort Pitt.
Four other occasions when British forces used infected blankets against enemy tribes are well document in records of the Hudson Bay Company, The East India Company and the Northwest Company.
“Many Native American tribes experienced great depopulation, averaging 25–50 percent of the tribes' members lost to disease. Additionally, smaller tribes neared extinction after facing a severely destructive spread of disease.[2] The significant toll that this took is expounded upon in the article Population history of indigenous peoples of the Americas. A specific example was Cortes' invasion of Mexico. Before his arrival, the Mexican population is estimated to have been around 25 to 30 million. Fifty years later, the Mexican population was reduced to 3 million, mainly by infectious disease. This shows the main effect of the arrival of Europeans in the new world. With no natural immunity against these pathogens, Native Americans died in huge numbers.”
The Mexican National Archive tells a different story. Mexico, inclusive of southern Panama, through northern California and all lands west of what would later be known as the Indiana Territory, inclusive of what we would be known as Louisiana and Florida, had an estimated population of 37 million, started collapsing as the Aztec empire commenced self destruction, with full blown wars between the Aztecs and subject states accounting for a population loss of more than 20%. The Aztecs descended into complete descent hastened by the arrival of the Spanish who they saw as Gods. Continued wars with subject states, civil wars, and accompanying starvation and pestilence further reduced the population by another 20%, with small pox and far more devastating measles epidemics killing off another 10-12% of the population during the 50 years subsequent to the arrival of Spanish and Portuguese missionaries, and later Conquistadors.
“By 1700, less than five thousand Native Americans remained in the southeastern coastal region.[4] In Florida alone, there were seven hundred thousand Native Americans in 1520, but by 1700 the number was around 2000.[4]”
The Apalachicola, other Muskogean ethnic groups of the Florida panhandle, an ethnic deviation from all other Native American peoples, had their own written language. Basically a Eurasian group, their records from the early 16th century showed a Florida population of less than 2k, with worries about population maintenance and religious purity. There were only a scattering of other occupants throughout Florida. Other Native American groups avoided the Apalachicola, other Muskogean ethnic groups because they feared their supernatural powers. As Seminoles, escaped Creek and Choctaw slaves of the British in the northern colonies escaped, they started moving into Florida during the early 17th century, intermarrying with The Apalachicola, and other Muskogean ethnic groups, adopting their language, both verbal and written. By the time Andy Jackson was president, there were less than 70k people living in all of Florida, tho wild speculatory reports claimed a million or more, using their numbers to catalyze wars with threatening tribes of the south. Also leading to causes for later acquisition by the US from Britain, even tho a British treaty with Spain promised the return of Florida to Spain. Part of the settlement and treaties ending the War of 1812.
Here's a kicker for you, the gene patterns for the Apalachicola and Muskogean ethnic groups display more connections with the Ainu of Japan, the Hza of northern Korea, and the Chulu peoples of New Zealand than with other Native Americans. This is a gene pattern that is know to have come out of northern India about 8000 BC, and it is found in northwestern Russia as well as among Inuit peoples of the Arctic. Archeologists are suspecting that this gene pattern was part of a distinct early wave of peoples from Eurasia into the Americas across the arctic continent. Additional evidence of the gene pattern has also been found in Patagonia, parts of the Peruvian mountain ranges. An interesting beginning for new migration theories.
