Pierre Dominic Toussaint, known as Toussaint L'Ouverture, joined these Maroon bands, where he was called "the doctor of the armies of the king," and soon became chief aid to Jean Francois and Biassou. Upon their deaths Toussaint rose to the chief command. He acquired complete control over the blacks, not only in military matters, but in politics and social organization; "the soldiers regarded him as a superior being, and the farmers prostrated themselves before him. All his generals trembled before him (Dessalines did not dare to look in his face), and all the world trembled before his generals."[82] The revolt once started, blacks and mulattoes murdered whites without mercy and the whites retaliated. Commissioners were sent from France, who asked simply civil rights for freedmen, and not emancipation. Indeed that was all that Toussaint himself had as yet demanded. The planters intrigued with the British and this, together with the beheading of the king (an impious act in the eyes of Negroes), induced Toussaint to join the Spaniards. In 1793 British troops were landed and the French commissioners in desperation declared the slaves emancipated. This at once won back Toussaint from the Spaniards. He became supreme in the north, while Rigaud, leader of the mulattoes, held the south and the west. By 1798 the British, having lost most of their forces by yellow fever, surrendered Mole St. Nicholas to Toussaint and departed. Rigaud finally left for France, and Toussaint in 1800 was master of Hayti. He promulgated a constitution under which Hayti was to be a self-governing colony; all men were equal before the law, and trade was practically free. Toussaint was to be president for life, with the power to name his successor. Napoleon Bonaparte, master of France, had at this time dreams of a great American empire, and replied to Toussaint's new government by sending twenty-five thousand men under his brother-in-law to subdue the presumptuous Negroes, as a preliminary step to his occupation and development of the Mississippi valley. Fierce fighting and yellow fever decimated the French, but matters went hard with the Negroes too, and Toussaint finally offered to yield. He was courteously received with military honors and then, as soon as possible, treacherously seized, bound, and sent to France. He was imprisoned at Fort Joux and died, perhaps of poison, after studied humiliations, April 7, 1803.
