By the mid 1630s, a new group of 700 even holier Europeans calling themselves Puritans had arrived on 11 ships and settled in Boston-which only served to accelerate the brutality against the Indians.
In one incident around 1637, a force of whites trapped some seven hundred Pequot Indians, mostly women, children, and the elderly, near the mouth of the Mystic River. Englishman John Mason attacked the Indian camp with “fire, sword, blunderbuss, and tomahawk.” Only a handful escaped and few prisoners were taken-to the apparent delight of the Europeans:
To see them frying in the fire, and the streams of their blood quenching the same, and the stench was horrible; but the victory seemed a sweet sacrifice, and they gave praise thereof to God.
This event marked the first actual Thanksgiving. In just 10 years 12,000 whites had invaded New England, and as their numbers grew they pressed for all-out extermination of the Indian. Euro-diseases had reduced the population of the Massachusett nation from over 24,000 to less than 750; meanwhile, the number of European settlers in Massachusetts rose to more than 20,000 by 1646.
