<P> In mid-June, John Mason set out from Saybrook with 160 men and 40 Mohegan scouts led by Uncas . They caught up with the refugees at Sasqua, a Mattabesic village near present - day Fairfield, Connecticut . The colonists memorialized this event as the Fairfield Swamp Fight (not to be confused with the Great Swamp Fight during King Philip's War). The English surrounded the swamp and allowed several hundred to surrender, mostly women and children, but Sassacus slipped out before dawn with perhaps eighty warriors and continued west . </P> <P> Sassacus and his followers had hoped to gain refuge among the Mohawk in present - day New York .

About 200 Pequots survived the war; they finally gave up and submitted themselves under the authority of the sachem of the Mohegans or Naragansetts: </P> <Table> <Tr> <Td> "</Td> <Td> There were then given to Onkos, Sachem of Monheag, Eighty; to Myan Tonimo, Sachem of Narragansett, Eighty; and to Nynigrett, Twenty, when he should satisfy for a Mare of Edward Pomroye's killed by his Men . The Pequots were then bound by Covenant, That none should inhabit their native Country, nor should any of them be called PEQUOTS any more, but Moheags and Narragansatts for ever . </Td> <Td>" </Td> </Tr> </Table>
