The Blues sustained heavy casualties in the Battle of Murfreesboro in Tennessee. The following year they marched to Mississippi in an effort to relieve the Siege of Vicksburg and in the fall of 1863, they fought in the battles of Chickamauga and Chattanooga. In the spring of 1865 the unit was in the Carolinas trying to slow the advance of General William Tecumseh Sherman after Sherman's 'March to the Sea'.
