The Narragansetts later had conflict with the Mohegans over control of the conquered Pequot land. In 1643, Miantonomi led the Narragansetts in an invasion of eastern Connecticut where they planned to subdue the Mohegans and their leader Uncas. Miantonomi had an estimated 1,000 men under his command. The Narragansett forces fell apart, and Miantonomi was captured and executed by Uncas' brother. The following year, Narragansett war leader Pessicus renewed the war with the Mohegans, and the number of Narragansett allies grew.
