6 April 1840 to 5 July 1849. Hyde is called on a mission to the Northeastern States and has some success. He records much of Brigham Young's speech refuting Sidney Rigdon's claim to lead the church and hears Brigham speak with Joseph Smith's voice. Hyde leaves Nauvoo with the Saints and joins the Mormon Battalion at Council Bluffs, Iowa. The paymaster at Fort Leavenworth, Kansas is impressed by the literacy of the Battalion. Colonel Allen dies and is greatly missed by the Battalion. The Battalion surgeon is universally despised and avoided by sick men. They reach Santa Fe, New Mexico and, traveling on, live on reduced rations. Hyde's journal emphasizes the difficulty of the trail and the occasional cruelty of officers. The Battalion safely arrives in San Diego, and they are congratulated by Lieutenant Colonel George Cook and do a variety of work in the city. On being mustered out, Hyde travels back to Winter Quarters via Salt Lake City and takes his family to the Salt Lake Valley.
