6 May 1842, the day Boggs was shot.
Nauvoo is approximately three hundred miles from Independence, Missouri. This journal entry records Butterfield’s assertion that JS attended a meeting of the Masonic lodge in Nauvoo from six to nine o’clock on 6 May 1842; however, JS’s name is not among those listed as present in the lodge minutes. According to his journal, JS was involved in activities with the Nauvoo Legion that day. (Nauvoo Masonic Lodge Minute Book, 6 May 1842; JS, Journal, 6 and 7 May 1842.)
