In Aristocrat in Uniform, Rembert W. Patrick delivers a compelling portrait of General Duncan Lamont Clinch, a Southern military officer whose career spanned some of the most formative and turbulent years in early American history. From the War of 1812 through the Seminole Wars and into the antebellum period, Clinch stood at the nexus of frontier warfare, Native American removal, and Southern political life. Patrick's biography draws on military records, personal correspondence, and government documents to reconstruct Clinch's life as both a soldier and planter, illuminating the tensions between duty, landholding privilege, and regional loyalty. The book explores Clinch's controversial role in the forced displacement of Native peoples and his participation in the U.S. Army's expansionist mission, while also offering insight into his aristocratic values, family life, and political ambitions. Rich in detail and interpretive nuance, Aristocrat in Uniform is a vital contribution to Southern biography and early American military history, capturing a figure emblematic of both honor and contradiction in the Old South.
