In 1643, a quarrel broke out between Uncas and a sachem named Sequasson, and after the English had ineffectually attempted to preserve peace between them, Uncas attacked Sequasson, killing seven or eight of his men, and securing considerable booty.[585] The defeated sachem was an ally of the Narragansett chief Miantanomo, who requested permission from the English for liberty to revenge himself upon the Mohegan. This was granted, and Miantanomo, followed by a thousand warriors, fell upon Uncas, who was supported by less than one half that number.[586] The Mohegans, nevertheless were successful, and Miantanomo was taken prisoner, through treachery. It will be recalled that Samuel Gorton had bought his lands through the Narragansett chief from two of his sachems, who had subsequently repudiated the transaction, and placed themselves under the jurisdiction of Massachusetts. It will be remembered also that Miantanomo, in spite of recent suspicions, had consistently been a friend of the English, that he had sheltered Williams, when banished from Massachusetts, and that, through the influence of the latter, the Narragansetts had sided with the colonists in the Pequot war. Gorton now unwisely tried to save the savage's life by writing a letter to Uncas, threatening him should he harm his prisoner.[587] Uncas, upon its receipt, hurried the captive to Hartford, to advise with the authorities as to what course he should take. At Miantanomo's own request, he was placed in custody of the English. Footnote 585: J. Winthrop, _History_, vol. II, p. 155. Footnote 586: _Acts United Colonies_, vol. I, p. 11. Footnote 587: J.
