Illinois governor Thomas Ford calls for the state militia in eleven counties to "proceed by voluntary enlistment to enrol as many men as can be armed in their respective regiments. They will make arrangements for a campaign of twelve days, and will provide themselves with arms, ammunition, and provisions accordingly, and hold themselves in readiness immediately to march upon the receipt of further orders."
Ford is worried that Mormons will attack Carthage in retaliation for Joseph Smith's assassination. In Nauvoo thousands pass by the bodies of Joseph and Hyrum. The Nauvoo Legion "was paraded and stationed in different parts of the City apprehending an attack by the enemy."
