Let's not come down too hard on Madison.
Support for the revolt was far from unanimous. The presence of competing pro-Spanish, pro-American, and pro-independence factions, as well as the presence of scores of foreign agents, contributed to a "virtual civil war within the Revolt as the competing factions jockeyed for position." The faction that favored the continued independence of West Florida secured the adoption of a constitution at a convention in October. The convention had earlier commissioned an army under General Philemon Thomas to march across the territory, subdue opposition to the insurrection, and seek to secure as much Spanish-held territory as possible. "Residents of the western Florida Parishes proved largely supportive of the Revolt, while the majority of the population in the eastern region of the Florida Parishes opposed the insurrection. Thomas' army violently suppressed opponents of the revolt, leaving a bitter legacy in the Tangipahoa and Tchefuncte River regions."
Of course, there were indigenous residents too, whose ancestors had resisted occupation until disease reduced them.
