On Friday evening, January 9, 1863, Abraham Lincoln held a private meeting at the White House with two key Republican senators –John P. Hale of New Hampshire and Orville H. Browning of Illinois—where he boasted proudly about the reaction of Missouri’s enslaved population to his recently issued Emancipation Proclamation. While pointing at a map of the western borderland area, featuring Missouri, Illinois, Indiana, and Ohio, the president claimed that since the first public announcement of emancipation (September 22, 1862), “the negroes were stampeding in Missouri,” creating a backlash among Democrats in that region. Lincoln wanted to use this moment to press for a compensated abolition measure in Missouri, describing this Western slave state, according to the revealing but little-known entry in Browning’s diary, as “an empire of herself,” claiming it would be more than “enough” for the legacy of each of these three men, “if we make Missouri free.” Lincoln’s use of the concept of the slave stampede was surely no accident. He had personal experience with that term, because he had seen it bandied about in
Springfield newspapers about a dozen years earlier, when his neighbor, Jameson Jenkins, a free black drayman, was accused of orchestrating a “slave stampede” from Missouri during the early weeks of 1850. Modern scholarship on the Underground Railroad and emancipation has not done enough to emphasize the impact of this concept of the “slave stampede” on the mindset of politicians like Lincoln. Nor has there been quite enough attention to the importance of mass escapes within the overall process of seeking freedom in antebellum America.
