 One of the primary reasons for the separation from Providence was dissension over admitting Samuel Gorton and his Warwick friends to equal rights in Providence . After being evicted from other places Gorton attempted to join in the Providence government , but the Pawtuxet settlers wanted no part of him or his followers . On a personal level , Gorton had bought from the Indians some of the same land that Arnold had bought four years earlier and attempted to seize the land . Another cause of dissatisfaction was Gorton 's treatment of the Indians . Having acquired the language of the Narragansett people , Arnold felt a strong affinity towards them , and in a long letter to Governor John Winthrop of Massachusetts in 1648 he complained of the injustice shown them by Gorton and the other Warwick settlers .
