During the winter of 1846 - 47, Latter - day Saint leaders in Winter Quarters and Iowa laid plans for the migration of the large number of Saints, their equipment, and their livestock. It was here that Brigham Young first met Thomas L. Kane, a non-Mormon from Philadelphia with deep personal connections to the Polk administration. Kane obtained permission for the Mormons to winter on Indian territory, and the site was originally called Kanesville. Brigham Young continued to trust Kane throughout his own lifetime, particularly as an intermediary with the often hostile Federal government. This major undertaking was a significant test of leadership capability and the existing administrative network of the recently restructured Church. For his role in the migration, Brigham Young is sometimes referred to as the ``American Moses. ''
