Free blacks and mulattos also fled the uprising. Mulattos could own slaves and plantations, and many of them did. Free blacks often manned the militias used to hunt down runaway slaves. Like the white settlers, both groups therefore had reason to flee. But states such as South Carolina feared the consequences of their influence on the states own slave population.
EDENTON, November 9th.
The Governor of South Carolina has issued a proclamation, requiring and ordering all free negroes and people of color, who have arrived there from St. Domingo, or who have arrived within twelve months from any other place, to depart the state in ten days from the date thereof, many characters amongst them being deemed dangerous to the welfare and peace of that state.
