The summer of 1614 was the first time that the Pequots encountered white settlers. They started trading furs for the settlers' goods, such as steel knives, needles, and boots. In 1633, the Dutch bought land from them and opened a fur trading post. Meanwhile, the English bought land for settlement from the local tribes. The Dutch had unintentionally killed the Pequots' chief, and this prompted revenge by the Pequot tribe, and this escalated into the Pequot War (1636–38). On the night of May 26, 1637, the Colonial forces arrived outside the Pequot village near the Mystic River. The palisade surrounding the village had only two exits, and their leader Colonel John Mason gave the order to set the village on fire and block off the exits. Those who tried climbing over the palisade were shot; anyone who succeeded in getting over was killed by the Narragansett forces.
