Does he explain how the military passed around smallpox-infested blankets without miraculously avoiding infection themselves?

Smallpox was endemic to the European population of the US. Many people were exposed to it in childhood and had immunity, but not as much exposure as Europeans. During the Revolutionary war, the British used smallpox as a weapon against Americans, because almost all British born soldiers had been exposed to smallpox as children while many Americans had not been exposed to it. Military use of smallpox during the American Revolution is the main reason why Canada is a separate country today.

Can you provide documentation for this? I have never heard it asserted before that immunity is possible absent vaccination.
