Was the architect of British North America a pioneer of biological warfare?

In short: Jeffery Amherst, the first British governor general of Canada, secured victory in the Seven Years' War, ending French rule in North America. Yet, his legacy is deeply stained by his explicit support for using smallpox-infested blankets to decimate American Indian tribes during the 1763 uprising known as Pontiac's War.

Born in 1717, Jeffery Amherst rose through the ranks of the British Army, gaining fame for his successful siege of Louisbourg in 1758. As commander-in-chief in North America, he orchestrated the capture of Quebec City and Montreal, effectively dismantling French colonial power. His military success was so celebrated that he was knighted in 1761 and appointed Governor-General of British North America in 1760. However, his tenure was marked by a rigid, often brutal approach to colonial administration and indigenous relations.

The most controversial chapter of his career occurred during Pontiac's War, an uprising by a confederation of tribes resisting British occupation. Correspondence between Amherst and Colonel Henry Bouquet reveals that Amherst explicitly endorsed the use of smallpox as a weapon to 'extirpate' what he termed an 'execrable race.' While historical records confirm that blankets from a smallpox hospital were distributed to Lenape representatives at Fort Pitt in June 1763, historians debate whether this specific act caused the subsequent outbreak, as the virus was already circulating in the region. Regardless of the biological outcome, the intent remains a documented stain on his record.

Amherst's later career in Britain was equally fraught. Though he served as commander-in-chief of the British Army twice and was raised to the peerage in 1776, his reputation suffered as he aged. He was heavily criticized for his handling of the 1780 Gordon Riots and his perceived incompetence during the French Revolutionary Wars. By the time of his death in 1797, contemporaries like Horace Walpole described him as a man whose 'stupidity and incapacity are past belief.' Today, while his name persists on numerous North American towns and institutions, his historical memory is increasingly defined by his ruthless conduct toward indigenous peoples.
