There were a great many petty officers, and some sectarian priests, who could descend to any level. Human butchery, if "Mormons" were the victims, was to them but a recreation. Such a man was Col. William O. Jennings, of the state militia. Another was Captain Nehemiah Comstock, who served under Jennings. These "brave" men with an armed force of characters like themselves--all from the state troops--were assembled, at the close of the month of October, 1838, near a small settlement of the Saints at Haun's Mill, on Shoal Creek, about twelve miles due east of Far West. On the 28th day of that month, a Sunday, Jennings approached the settlement and proposed a treaty of peace. The members of the Church located there, who were quietly minding their own business, knew not, when they were at peace, why they should be called on to enter into such an agreement. However, knowing the status of affairs throughout upper Missouri, they gladly entered into such a treaty, and continued with their domestic affairs, feeling perfectly secure. In the meantime Col. Ashley had informed Col. Jennings of the governor's order of extermination. Thereupon Jennings and Nehemiah Comstock gathered their forces, about two hundred and forty men, and immediately started for Haun's Mill.
Monday, October 29, 1838, passed in peace and quiet. Tuesday the 30th was clear and pleasant, an Indian summer day. In the afternoon, the Saints were engaged in their daily pursuits, the men in the fields and the shops; the women attending to domestic duties, and the children playing on the banks of the creek. Suddenly Jennings and his force approached at full speed, riding upon the settlement. David Evans, perceiving their evil intentions, raised his hands as a sign of peace; but they heeded him not. Continuing their advance, they commenced to fire. The stricken people fled, seeking shelter and endeavoring to escape. Some fled into the thickets near their homes, and by this means escaped. For lack of time and want of a better protection, several of the men and boys rushed into the blacksmith shop. The cracks between the logs of the shop were so wide that the fiends on the outside could see their victims within. Surrounding the place, they poured volley after volley through the cracks with deadly effect. Several intended victims rushed from the shop amidst the fire of the mob; some escaped to the thicket; others were shot. Miss Mary Steadwell, while fleeing, was shot in the hand and fainted; falling over a log she remained protected by it. After the work of destruction was over, more than twenty musket balls were discovered in the log. Yet the executioners were principally seeking for the men, and let most of the women escape.
