Set within a larger analysis of class relations in the Haitian Revolution, this is a microhistory that intersects with several important themes in the revolution: rumor, atrocity, the arming of slaves, race relations, and the origins and wealth of the free colored population. It is an empirical investigation of an obscure rebellion by free men of color in the Grande Anse region in 1791. Although the rebellion is obscure, it is associated with an atrocity story that has long resonated in discussion of the revolution. Formerly the least-known segment of Caribbean society, research has shed much new light on free people of color in recent decades, but much remains to be clarified. In certain ways, they are the key to understanding the Haitian Revolution, because of their anomalous position in Saint Domingue society and the way their activism precipitated its unraveling. The Grande Anse region had a unique experience of the revolution in that white supremacy and slavery were maintained there longer than in any other part of the colony. Based primarily on unexploited or little-known sources the article demonstrates the range and depth of research that remains possible and suggests that a regional focus is best way to advance current scholarship on the Haitian Revolution.
