Born in Lexington, Kentucky, but drawn by the promise of the growing West, Shelby became one of the richest men in Missouri. Siding with the Confederacy at the outbreak of the Civil War, he organized his Iron Brigade of cavalry?whose ranks included Frank and Jesse James?taught his men a slashing frontier style of fighting, and led them on incredible raids against Federal forces in Missouri. When the Confederacy fell, Shelby refused to surrender and instead took his command to Mexico, where they fought in support of the emperor Maximilian. Upon his return to Missouri, Shelby became an immensely popular figure in the state, eventually attaining the status of folk hero, a living symbol of the Civil War in the West.
