 Having already become proficient in the Narragansett and Wampanoag native languages , and harboring an intense dislike of Gorton , Arnold and his father devised a scheme to undermine their adversary , and to simultaneously obtain extensive lands from the local Indians . Gorton had purchased Shawomet from Miantonomi , the chief sachem of the Narragansett people . Two minor sachems , <unk> and <unk> , had some control of the lands at Pawtuxet and Shawomet , and Arnold , acting as interpreter , took these chieftains to Governor Winthrop in Boston , and had them submit themselves and their lands to Massachusetts , and claim that the sale of Shawomet to Gorton was done " under duress . " Now with a claim to Shawomet , Massachusetts directed Gorton and his followers to appear in Boston to answer " complaints " made by the two minor sachems . When Gorton refused , Massachusetts sent a party to Shawomet to arrest Gorton and his neighbors . The ensuing trial had nothing to do with the land claims , but instead focused on the writings and beliefs of Gorton , for which he and others in his group were imprisoned . Ultimately , Gorton was released and went to England where he was given legal title to his lands from the Earl of Warwick , and in his honor the settlement of Shawomet was renamed Warwick .
