In 1817, following a land-grant Act of Congress, written to aide Napoleon-supporters in the War of 1812, 340 French families settled on four townships in Alabama. They arrived in Mobile, Alabama on the ship "McDonough" and made their headquarters in a small community named "White Bluff." A year later, with the community developed into a thriving village by their labors, they renamed it "Demopolis," an ancient Greek name meaning "City of the People." These Napoleonic exiles chose not to give it a French name that would recall their native land.
These cultured colonists, from the drawing rooms and military heritage of the old French aristocracy, were likely the least-prepared of any of the immigrant groups who settled the American wilderness, and soon found themselves pioneering the rugged interior of Alabama with illiterate traders, squatters and Indians for their neighbors. They called themselves "The Association of French Emigrants for the Cullivation of the Vine and Olive", but their attempt at olive and grape culture was a complete failure. The Indians taught them how to grow corn and beans, but when they discovered that through a surveying error they inadvertently had built their city outside the chartered boundaries, they drifted away, either returning to France or settling in Mobile or New Orleans. But Napoleon was no great hand when it came to reading maps and recognizing boundaries, either.
Director/writer George Waggner took the surveying mistake and converted it to a land-grab scheme, threw in a motley group of rugged Kentucky militiamen, returning from the Battle of New Orleans, used the most diverse cast in any of the American-frontier films from Republic...and then tossed in ten pounds of plot into a five-pound container. Most of which worked. Aside from the thematic song, a traditional called "Kentucky Marching Song", in which he wrote new lyrics to go with George Anthiel's arrangement. Neither of which, apparently, spent much time on the writing or the arranging.
