Utah Territory in the American Civil War

The Utah Territory (September 9, 1850 - January 4, 1896) during the American Civil War was far from the main operational theaters of war, but still played a role in the disposition of the United States Army, drawing manpower away from the volunteer forces and providing its share of administrative headaches for the Lincoln Administration. Although no battles were fought in the territory, the withdrawal of Union forces at the beginning of the war allowed the Native American tribes to start raiding the trails passing through Utah.
