The French had agreed to ally with the American Revolutionary forces following the royal ordinance issued by Louis XVI, the King of France, on March 12, 1779.
D’Estaing’s troops were mainly composed of colonial regiments coming from various locations such as Guadeloupe, Martinique, or Saint-Domingue. Of the 1,550, 800 men from the French Caribbean colony of Saint Domingue, present day Haiti, were organized into a regiment called Chasseurs-Volontaires de Saint-Domingue. These soldiers were Gens de Couleurs libres (Black and Mulatto free men of color) who voluntarily joined the French colonial forces.
They were allegedly born free and thus were distinct from free slaves or affranchis, who were born enslaved or became enslaved during their lives and then freed themselves or were freed. This distinction allowed the Gens de Couleur a higher social and political position in the French colonial West Indies. According to the 1685 French Black Code, they had the same rights and privileges as the white colonial population. In practice, however, strong discrimination by white French colonial residents impeded the gens de couleurs from fully exercising them.
Nevertheless, due to their in-between status, some men joined the Chasseurs-Volontaires formed after the March 12, 1779 royal ordinance. They became part of the French command which supported the Continental Army in Savannah. In fact, the gens de couleurs outnumbered the 500 American troops at the Battle of Savannah. Their role in the battle was also significant because they were sent in as scouts before the beginning of the hostilities on September 8, 1779.
