This biographical dictionary catalogs the Union army colonels who commanded regiments from Missouri and the western States and Territories during the Civil War. The seventh volume in a series documenting Union army colonels, this book details the lives of officers who did not advance beyond that rank. Included for each colonel are brief biographical excerpts and any available photographs, many of them published for the first time.

Much of Civil War history emphasizes generalship (or the lack of it) as the key factor in analyzing why battles were won or lost. Taking an innovative approach, this book focuses on six elements of victory in nine important Western Theater engagements during 1862--a year when the North had not yet fully mobilized for war. With increasing complexity on the battlefield and the enormous growth of American armies, winning or losing depended upon achieving as many of these six critical goals as possible: a clear objective; mobilization of effective lieutenants; a competent staff; seizing and holding initiative; deploying all available resources; and realizing a successful strategic outcome. The more goals achieved, the greater the victory.

Lyman Gibson Bennett (1832–1904) had a curious mind and a keen sense of humor. He had an engineer’s mentality and a poet’s grasp of language, except for spelling. As a Union soldier, Bennett saw extensive service in the Trans-Mississippi Theater. A writer of considerable energy and intelligence, Bennett’s wartime diaries recount his diverse and wide-ranging military record, stretching geographically from the prairies of Illinois to the Rocky Mountains, while a postwar account details, among other things, his labors to recruit “Mountain Feds” in the Ozarks. This volume provides the perspective of an individual who was both a topographical engineer—with extensive experience that spanned the country from Arkansas to the Overland Trail—and a common soldier. As a member of the Thirty-Sixth Illinois Infantry, Bennett provided one of the most detailed contemporary accounts of the pivotal Battle of Pea Ridge, March 7–8, 1862. By December 1863, Bennett was promoted to first lieutenant in the newly formed Fourth Arkansas Cavalry (US) and wrote an invaluable first-person account of guerrilla fighting in the Ozark mountains. Readers will delight in Bennett’s witty descriptions of the ankles (and even higher!) of ladies as they gathered their skirts to trek through the mud; his sometimes-cutting words about his fellow hospital patients; and his wry comments on that “exclusively southern institution,” the chigger. New Fields of Adventure will prove useful to scholars of the Ozarks, landscape studies, and the Civil War in the West.
