Though its most famous battles were waged in the East at Antietam, Gettysburg, and throughout Virginia, the Civil War was clearly a conflict that raged across a continent. From cotton-rich Texas and the fields of Kansas through Indian Territory and into the high desert of New Mexico, the Trans-Mississippi Theater was site of major clashes from the war’s earliest days through the surrenders of Confederate generals Edmund Kirby Smith and Stand Waite in June 1865. In this comprehensive military history of the war west of the Mississippi River, Thomas W. Cutrer shows that the theater’s distance from events in the East does not diminish its importance to the unfolding of the larger struggle.
