The Whitman massacre ended with the death of fourteen people at the mission, including Marcus, Narcissa, and John and Francis Sager. Another fifty-four women and children were captured and held for ransom, including the daughters of Joseph Meek and Jim Bridger and all the Sager girls. Several of the prisoners died in captivity, mostly from illnesses such as measles, including Helen Mar Meek and Louisa Sager. One month after the massacre, on December 29, 1847, Peter Skene Ogden from the Hudson's Bay Company arranged an exchange of sixty-two blankets, sixty-three cotton shirts, twelve rifles, six hundred loads of ammunition, seven pounds of tobacco, and twelve flints for the return of the forty-nine surviving prisoners. They were brought to Fort Vancouver.
