July 4, 1675, Governor John Leverett sent Edward Hutchinson to sign a treaty with the Narragansets whereby they would agree not to harbor any of Metacomet's people. Hutchinson decided "to treat with the Narragansets sword in hand," and forced Pumham to sign on July 15. Pumham and his people ignored the treaty as soon as the colonists left.

Pumham was captured in Dedham, Massachusetts
