Although Lee surrendered at Appomattox Court House in April, 1865, some Confederates refused to abandon their cause. Fallen Guidon , originally published in 1962 by Jack Rittenhouse's Stagecoach Press in 1962, is the gripping story of one such group of men who, rather than surrender, boldly decided to follow their cavalry flag or guidon south and transplant their imperialistic vision in the troubled soil of Mexico. This little-remembered episode of the Trans-Mississippi Civil War was written as a popular history by the late Edwin Adams Davis, a respected scholar of southern and Civil War history.
General Jo Shelby had led the Missouri Cavalry Division through battles at Westport, Mine Creek, Newtonia, and elsewhere. Shelby's men were all recruits rather than draftees, fiercely loyal, and they followed the code of chivalry to a degree unusual even in the old South. While preparing to march against the Federals at Little Rock, they heard of Lee's surrender. In a meeting at Marshall, Texas, Shelby announced, "We will stand together, we will keep our organization, our arms, our discipline, our hatred of oppression . . . that this Missouri Cavalry Division preferred exile to submission--death to dishonor." Having heard that the U.S. government wanted the Habsburg emperor Maximilian out of Mexico and that Lincoln liked the idea of ex-Confederates joining forces with Benito Juarez to oust Maximilian and his French military forces, Shelby formed his plan. Shelby believed he had found a way to save their honor and at the same time spread their lost southern empire to a new land, where riches and glory surely awaited them.
Shelby and his men marched through Texas, stopping in Corsicana, Tyler, Waxahachie, Waco, Austin, Houston, and San Antonio, declaring martial law and forcibly quelling local outbreaks of looting and rioting where they found it. At the Rio Grande, in a funereal memorial, they buried their Confederate battle flag in the murky waters before heading into Mexico. Shelby's men did not want to support Benito Juarez's liberal guerrillas, however. Identifying themselves as "imperialists," they wanted to fight gloriously for Emperor Maximilian. In pitched battles against the local Juaristas and isolated guerrillas and bandits, they spilled blood from Piedras Negras to Mexico City and even undertook the chivalrous and bloody rescue of a woman imprisoned in a hacienda. Once in Mexico City, Shelby's "Iron Brigade" discovered its march to have been futile, and in a bittersweet final review, Shelby said good-bye.
