With Bible passages in their hands to justify their every move, the Puritans began their march inland from the seaside communities. Joined by British settlers, they seized land, took the strong and young Natives as slaves to work the land, and killed the rest. When they reached the Connecticut Valley around 1633, they met a different type of force. The Pequot Nation, very large and very powerful, had never entered into the peace treaty negotiated by Squanto as had other New England Native nations. When two slave raiders were killed by resisting Natives, the Puritans demanded that the killers be turned over to them. The Pequot refused. What followed was the Pequot War, the bloodiest of the Native wars in the northeast.
An army of over 200 settlers was formed, joined by over 1,000 Narragansett warriors. Because of the lack of fighting experience, and the vast numbers of the fierce Pequot warriors, Commander John Mason elected not to stage an open battle. Instead, the Pequot were attacked, one village at a time, in the hours before dawn. Each village was set on fire with its sleeping Natives burned alive. Women and children over 14 were captured to be sold as slaves; other survivors were massacred. The Natives were sold into slavery in The West Indies, the Azures, Spain, Algiers and England; everywhere the Puritan merchants traded. The slave trade was so lucrative that boat loads of 500 at a time left the harbors of New England.
In 1641, the Dutch governor of Manhattan offered the first scalp bounty; a common practice in many European countries. This was broadened by the Puritans to include a bounty for Natives fit to be sold for slavery. The Dutch and Puritans joined forces to exterminate all Natives from New England, and village after village fell. Following an especially successful raid against the Pequot in what is now Stamford, Connecticut, the churches of Manhattan announced a day of “thanksgiving” to celebrate victory over the heathen savages. This was the 2nd Thanksgiving. During the feasting, the hacked off heads of Natives were kicked through the streets of Manhattan like soccer balls.
The killing took on a frenzy, with days of thanksgiving being held after each successful massacre. Even the friendly Wampanoag did not escape. Their chief was beheaded, and his head placed on a pole in Plymouth, Massachusetts — where it remained for 24 years. Each town held days of thanksgiving to celebrate their own victories over the Natives until it became clear that there needed to be an order for these special occasions. It was George Washington who finally brought a system and a schedule to thanksgiving when he declared one day to be celebrated across the nation as Thanksgiving Day.
