[Joseph Smith] tells his brother Hyrum to take his family to Cincinnati. Hyrum answers, "Joseph, I can't leave you." Joseph says, "I wish I could get Hyrum out of the way, so that he may live to avenge my blood."
Willard Richards writes James Arlington Bennett on behalf of Joseph, asking for his help, stating, "All the horrors of Missouri's murders are crowding thick upon us. . . . [We] invite you to come to our assistance with as many volunteers as you can bring. . . . Will you come? . . . If you do not, your turn may come next; and where will it cease?"
