In 1802, he was appointed to lead an expeditionary force against Saint-Domingue (Haiti) after General Charles Leclerc's death. His remit was to restore French control of their rebellious colony, by any means. Historians of the Haitian Revolution credit his brutal tactics for uniting black and gens de couleur soldiers against the French. After Rochambeau surrendered to the rebel general Jean-Jacques Dessalines in November 1803, the former French colony declared its independence as Haïti, the second independent state in the Americas. In the process, Dessalines became arguably the most successful military commander in the struggle against Napoleonic France.[2]
During his time in Haiti, Rochambeau waged a war of extermination, massacring thousands of blacks of all ages and genders. In 1803, he developed the world's first gas chambers. He used a rudimentary method of filling ships' cargo holds with sulfur dioxide to suffocate black prisoners of war.[3][4]
At the surrender of Cap Français, Rochambeau was captured aboard the frigate Surveillante by a British squadron under the command of Captain John Loring and returned to England as a prisoner on parole, where he remained interned for almost nine years.
He was exchanged in 1811, and returned to the family château, where he resumed the work of classifying the family's growing collection of maps, which his father had begun. He also enriched the collections with new acquisitions, in particular ones contributed by the military campaigns of his son, Auguste-Philippe Donatien de Vimeur, who served as the aide-de-camp for Joachim Murat and was with Murat's cavalry in the Russian campaign in 1812.
He was mortally wounded in the Battle of Nations, and died three days later at Leipzig, at the age of 58.
In addition to his legitimate son, Vimeur was survived by an illegitimate son, Lewis Warrington, conceived in Williamsburg, Virginia, when Vimeur was a young officer serving with his father in America during the Revolutionary War.[citation needed]
