John Underhill's men massacre more than 100 Indians near present-day Massapequa. Governor Willem Kieft, who hired Underhill for 25,000 guilders to kill Indians, declares a day of thanksgiving. It is said that Underhill’s men pile the bodies of the dead Indians in a single large mound. Locals claimed that the surrounding ground is stained red for almost 50 years afterward (“List of Indian massacres”).
