The Tennessee 12th Cavalry Battalion was formed in September, 1862, with four companies, later increased to seven. Its members were raised in Hawkins, Greene, Knox, Hamblem, and Grainger counties. The unit was assigned to Wharton's, J.J. Morrison's, H.B. Davidson's, Grigsby's, and Vaughn's Brigade. It fought at Perryville, Murfreesboro,and Monticello. Then from June, 1863, to March, 1864, the 12th and 16th Battalions were consolidated into a field organization known as Rucker's Legion. This command was active at Chickamauga and in Tennessee, and on January 31, 1864, totalled 171 effectives. During April, 1864, the 12th had 234 members and moved into the Valley of Virginia where it was engaged at Piedmont. The unit went on to skirmish in Virginia and East Tennessee, moved to North Carolina, and probably disbanded in Georgia during the spring of 1865.
