At the request of Union general Ulysses S. Grant, in 1864 Major General Frederick Steele stripped the Department of Arkansas of twelve thousand men—half its strength—to support an expedition in Louisiana. And while the depleted infantry remained largely in garrison, the 8th Missouri Cavalry and its counterparts were ordered to patrol central Arkansas under horrid conditions and protect the state from guerrilla Rebels. The regiment spent nine long months battling against Confederate general Jo Shelby's efforts to raid the White River Valley behind Union lines while simultaneously battling to secure Arkansas' borders. Join author David Casto as he explores the 8th Missouri Volunteer Cavalry's perilous excursion into enemy territory.
