[6] This riot occurred on June 14, 1833. Thornton Blackburn and his wife, the alleged runaways from Kentucky, were lodged in jail pending the departure of a boat. A crowd of colored men and women, armed with clubs, stones and pistols, gathered in the vicinity of the jail. Upon the pretext of visiting Blackburn's wife a colored woman was admitted to the jail and by an exchange of clothing effected the escape of the prisoner who immediately crossed into Canada. Some time thereafter the sheriff attempted to take his other prisoner to the boat, but was knocked down and badly beaten. During the encounter the sheriff fired into the mob, but Blackburn was rescued and carried to Canada. This caused a great disturbance among the white people. They armed themselves and attacked the blacks wherever they could be found. The city council convened and undertook to dispose of the trouble by enforcing the law of 1827 requiring that colored people should stay off the streets at night.

[7] Five years after the organization of the Detroit Anti-Slavery Society Henry Bibb, an ex-slave, came to the city and lectured for two years under the auspices of the Liberty Association, which was promoting the election of anti-slavery candidates. Public sentiment against slavery was becoming such that the Legislature of Michigan passed a law prohibiting the use of jails to detain fugitives. Frederick Douglass and John Brown found many friends of their cause in Detroit. Of the many organized efforts made to circumvent the law and assist fugitives one society purchased land and established homes for as many as 50 families between 1850 and 1872. Farmer, "History of Detroit and Michigan," I, Chapter XLVIII. [8] The immediate cause of the riot in Detroit was the arrest, conviction, and imprisonment of a colored man called William Faulkner charged with committing an assault on a little girl. Feeling that the prisoner was guilty, bands of ruffians swept through the streets and mercilessly beat colored people. Seven years later it was discovered that Faulkner was innocent and to reimburse him for his losses and humiliation the same ruffians raised a handsome sum to set him up in business. See Farmer's History of Detroit and Michigan, Chapter XLVIII. [8a] A study of the directories of Detroit shows that a considerable number of Negroes had entered the higher pursuits of labor. See especially the Detroit Directory for 1865. [9] Simmons, "Men of Mark," 356.
