Missing from the traditional Thanksgiving narrative—the brutal winter followed by the bountiful harvest—is the horrific epidemic that raged through the Native American community during the three years immediately preceding the 1620 arrival of the Mayflower. Rat feces on boot soles are believed to have carried lethal bacteria from European ships anchored along the New England coastline to Native villages. Whatever the precise nature of the disease, it worked with ruthless efficiency during the years 1616 to 1619. “The pace of death must have been terrifying,” Peter Mancall writes in The Trials of Thomas Morton, his book about a little-known chapter in the European settling of New England. “Most epidemics, even of highly contagious diseases like the plague, typically leave survivors. But this series of infections apparently killed almost everyone.” The Pilgrims regarded the “wonderfull Plague,” which decimated the Native farmers but left their cleared fields, as one more God-given thing to be thankful for.
Natives spared by the disease suffered another disaster in 1637, in what came to be known as the Pequot War but was more accurately a massacre. Colonists seized on various pretexts to slaughter 1,500 Natives in two months, including women and children in a village on the Mystic River that they deliberately torched. “It was a fearful sight to see them thus frying in the fire,” the Pilgrim leader William Bradford wrote of the atrocity, “and the streams of blood quenching the same.” Again, Bradford thanked a providential God for aiding his men, “thus to enclose their enemies in their hands and give them so speedy a victory over so proud and insulting an enemy.”
But there were other challenges to the Pilgrims’ fragile utopian experiment, and to the more worldly and successful Puritan colony of Massachusetts Bay, founded in 1630, that eventually absorbed it. This threat arose from fellow Englishmen, many of whom regarded the Pilgrims, with their astringent separatist views that had taken them first to Holland and then to New England, and the more moderate Puritans, who wished to reform the abuses of the Anglican Church, with distaste.
