The Jerry Rescue occurred on October 1, 1851, and involved the public rescue of a fugitive slave who had been arrested the same day in Syracuse, New York, during the anti-slavery Liberty Party's state convention. The escaped slave was William Henry, a 40-year-old cooper from Missouri whose slave name was "Jerry."

The Fugitive Slave Act or Fugitive Slave Law was a law passed by the 31st United States Congress on September 18, 1850, as part of the Compromise of 1850 between Southern interests in slavery and Northern Free-Soilers.
Print by E. W. Clay, an artist who published many proslavery cartoons, supports the Fugitive Slave Act of 1850. In the cartoon, a Southerner mocks a Northerner who claims his goods, several bolts of fabric, have been stolen. "They are fugitives from you, are they?" asks the slaver. Adopting the rhetoric of abolitionists, he continues, "As to the law of the land, I have a higher law of my own, and possession is nine points in the law."
The Vicksburg Whig did not cite any sources for these claims about the number of fugitives from American slavery ("Slaves Escaping from the South", January 16, 1861)
