"The Great Slave Escape of 1848 Ended in Bracken County"
"The Great Slave Escape of 1848 Ended in Bracken County" by John E. Leming, Jr., describes the attempt as "the largest single slave uprising in Kentucky history." A white man, Patrick Doyle, was the suspected leader of the slave revolt; he was to take 75 slaves to Ohio, where they would be free.
The armed contingent of slaves made its way from Fayette County, KY, to Bracken County, KY, where it was confronted by a group of about 100 white men led by General Lucius Desha of Harrison County, KY. During an exchange of gunfire, some of the more than 40 slaves escaped into the woods, but most were captured and jailed, along with Patrick Doyle. Doyle was sentenced to 20 years of hard labor in the state penitentiary, and the slaves were returned to their owners.
