This is a typescript of a diary of a Mexican War soldier who served in the "Mormon Battalion." The diary was kept from 16 July 1846 to 10 Sept. 1847 with a few entries for the years 1848-1855. He was also among the first groups to enter Salt Lake Valley in July of 1847. He went to Winter Quarters in August 1847 and went to Ogden, Utah in 1852. There are numerous gaps in this diary. The entries tend to be short but some are lengthy and detailed. Two small biographies of Andrew Jackson Shupe and his brother, James Wright Shupe, have been included.
