Scaramouche, the source of the Utah version would appear to be the manuscript diary of Andrew Jackson Allen 1818-1884 of Draperville, Utah. He was one of the Mormon pioneers of 1847, and kept a diary from 1848 until his death in 1884 which is a valuable record of the early Mormon days in Utah, including the Utah War of 1857. Copies of the diary, or of a typescript of it, are held by the University of Utah Library, the Utah State University Library and the Utah State Historical Society among others.
Some part, at least, of the diary may be viewed and downloaded from the Utah, Our Pioneer Heritage database but you need to be a registered subscriber to Ancestry.com. There is an offer of a free 14-day trial if you are willing to part with your credit card details and cancel them within 14 days. I'm not so trusting!
