How did reports from Guadeloupe and Martinique affect the struggle for Haitian independence?

Reports that France had reestablished slavery in Guadeloupe and Martinique played a pivotal role in the final stages of the Haitian struggle for independence.

Following the imprisonment of Toussaint Louverture in 1802, the Black and mulatto populations in Saint-Domingue were deeply enraged by evidence that Napoleon Bonaparte intended to restore the old colonial regime and slavery, as he had already done in other French possessions. This realization galvanized the resistance, leading leaders such as Jean-Jacques Dessalines, Henry Christophe, and Alexandre Sabès Pétion to unite their forces against the French.

The news from Guadeloupe and Martinique transformed the conflict into a desperate, unified struggle for survival and liberty. This collective resolve, combined with the devastating impact of yellow fever on French troops and the renewal of hostilities between France and Britain, ultimately led to the defeat of the French forces and the declaration of Haiti’s independence on January 1, 1804.12
