A few years later, Maquinna and his warriors captured the American trading ship "Boston" in March 1803. He and his men killed the captain and all the crew but two, whom they kept as slaves. After gaining release, John R. Jewitt wrote a classic captivity narrative about his nearly 3 years with the Nuu-chah-nulth and his reluctant assimilation to their society. This 1815 book is entitled "Narrative of the Adventures and Sufferings of John R. Jewitt;, Only Survivor of the Crew of the Ship Boston, during a Captivity of Nearly Three Years among the Savages of Nootka Sound: With an Account of the Manners, Mode of Living, and Religious Opinions of the Natives." In the end, Jewitt escaped with the help of Wickaninnish, a chief from an opposing group.
