Often neglected by historians, actions in Missouri and Kansas had an important influence on the course of the Civil War, with profound effects for the communities and people in the region. Outside of Virginia and Tennessee, Missouri was perhaps the most hotly contested territory during the war. The fighting in Missouri culminated with an expedition that re-wrote the books on tactics and the use of mounted infantry. This book focuses on the experiences of the soldiers, officers and civilians on both sides. The author brings to life the events in the region that contributed to the internecine strife in the Western Theater.
