Capois is mostly known for his extraordinary courage and especially his herculean bravery at the Battle of Vertières in which the French general Viscount of Rochambeau, commander of Napoleon's army in Saint-Domingue (colonial Haiti), even called a brief cease-fire to congratulate him.
After his success at Petit-Fort, he decided to attack Tortuga island (Île de la Tortue).
On the night of February 18, 1803, 150 soldiers under the command of Vincent Louis were huddled together on this frail means of transportation in tow of 2 rowboats.
[1] On November 18, 1803, Jean-Jacques Dessalines had ordered Capois to take Vertières, a fort situated upon a mount.
Capois-la-Mort advanced with a demi-brigade which, horribly mutilated, soon recoiled before the cannon fire coming from the fort.
Boiling with rage, Capois ran to seek other new troops and, mounting his horse, advanced for the third time; again the thousand deaths that vomited from the fortress repulsed him and his brigade.
The next morning, a French officer followed by his companions led to the headquarters of the Haitian army a horse caparisoned, and delivered him with these words: "The Captain-general (Rochambeau) offers this horse as a mark of admiration to the "black Achilles" to replace the one of his that the French army regrets having killed".
[1] On October 8, 1806, Capois was on his way to Cap-Haïtien when, near Limonade, he rode into a trap set for him, and was killed by assassins on the orders of Henri Christophe.
