That’s very possible but another narrative I’ve seen says that Squanto was a captive not a member of the Wampanoags. It does make me question the “plague” or sickness narrative but you’re right most sources say sickness killed his tribe.
I think there’s no doubt about the Indians of the Americas being almost wiped out by Old World diseases.
It wasn’t done on purpose, of course, as 16th Century Westerners had no idea how germs and viruses act—or even knew they existed.
But thousands of years of East/West traffic from the Far East to Europe and mankind there living cheek and jowl with poultry, swine and cattle meant many, many bacteria and viruses jumped species barriers and wiped out plenty of people in waves of plague. The Old World humans earned their immunity the hard way. The descendants of plague victims’ micros versus the peoples of hardly any disease clashed.
Bad news for Indians. Most of them died from diseases from people they never even saw.
