Considering that I had never heard of this person before I came across his name in regards to the Hurricane of 1812. He obviously had quite a varied and impactful life in both France and the United States.
Back in France, he received the Royal Order of St. Louis on 3 July 1779 and was made a major in the artillery on 5 April 1780.
In 1784, he was promoted to lieutenant colonel in the Fernch Army and stationed on Saint-Domingue (Haiti). In the slave revolt led by Toussaint L'Ouverture, he commanded troops battling the slaves and tried to persuade the local government to arm free Blacks but was ignored.
Nonetheless, Tousard was blamed for the failure of the colonial officials to obey orders from France in this regard and was arrested and imprisoned. U.S. pressure caused his release in February 1793 and he went to the United States and settled on a farm outside of Wilmington, Delaware.
And, his story still isn't over.
