Here is presented a transcript of the journal of Thomas Bullock during the period of 31 August 1845 to 5 July 1846. Bullock (1816–1885) was a historian for The Church of Jesus Christ of Latter-day Saints much of his life. This journal records the persecutions the Mormons endured in Nauvoo, Illinois. He writes of the life and trials of the Saints as well as his associations with Brigham Young, John Taylor, Parley P. Pratt, and many other prominent church figures of the day. Gregory R. Knight adds substantial footnotes that explain people and events recorded in the journal.
