On November 2, Plymouth Colony governor Josiah Winslow led a combined force of colonial militia against the Narragansett tribe. The Narragansetts had not been directly involved in the war, but they had sheltered many of the Wampanoag fighters, women, and children. Some of their warriors had participated in several Indian attacks. The colonists distrusted the tribe and did not understand the various alliances. As the colonial forces went through Rhode Island, they found and burned several Indian towns which had been abandoned by the Narragansetts, who had retreated to a massive fort in a frozen swamp. The cold weather in December froze the swamp so that it was relatively easy to traverse. The colonial force found the Narragansett fort on December 19, 1675 near present-day South Kingstown, Rhode Island; they attacked in a combined force of Plymouth, Massachusetts, and Connecticut militia numbering about 1,000 men, including about 150 Pequots and Mohican Indian allies. The fierce battle that followed is known as the Great Swamp Fight. It is believed that the militia killed about 600 Narragansetts. They burned the fort  of land) and destroyed most of the tribe's winter stores. Most of the Narragansett warriors  escaped into the frozen swamp. The colonists lost many of their officers in this assault; about 70 of their men were killed and nearly 150 more wounded.  The rest of the colonial assembled forces returned to their homes, lacking supplies for an extended campaign. The nearby towns in Rhode Island provided care for the wounded until they could return to their homes.
