Three Years Among the Comanches: The Narrative of Nelson Lee, Texas Ranger

This is a detailed account of Lee's captivity among the Comanches in the 1850's and his escape through the mountains back to white civilization. The story is full of encounters with alligators, snakes, and panthers, as well as hostile Comanches. Lee saw his fellow captives slaughtered most horribly: he was spared only because he convinced the Indians that the Great Spirit spoke to him through his pocket watch. Nevertheless, Lee gives excellent details about the tribe's way of life, albeit from the perspective of someone who doesn't have the kindliest feelings towards his captors.
