Uncas (Faithful). A chief of the Mohegans in their war against the Pequods, which Tribe, after being conquered were divided among the others, one hundred being alloted to Uncas. As a rival to Miantonomo of the Narragansetts, the latter hired a Pequod to kill him. Uncas was a man of immense strength and when he captured Miantonomo he spared his life until the English decided his fate. Uncas was a great friend of the English. J. Fennimore Cooper, in his work, “The Last of the Mohicans,” called one of his principal characters “Uncas.”
