The Tennessee 48th (Nixon's) Infantry Regiment was organized at Corinth, Mississippi, in April, 1862. It was formed with remnants of the 48th (Voorhies') and 54th Tennessee Regiments, plus a few additions from other units. It moved to Knoxville, fought at Richmond and Perryville, then remained in the Shelbyville and Estill Springs area for a time. During December, 1862, the four companies from Voorhies' Regiment transferred to their original organization. Attached to General L.E. Polk's Brigade, the remaining six companies were engaged at Chickamauga and from September, 1863, to April, 1864, were consolidated with the 35th Regiment. On July 31, 1864, Polk's Brigade was broken up and the men from Nixon's 48th Regiment merged into Voorhies' 48th Regiment. This unit lost nineteen percent of the 312 engaged at Richmond and fifty percent of the 155 at Chickamauga. In December, 1863, the 35th/48th (Nixon's) totalled 251 men and 207 arms.Companies Of The Tennessee 48th Infantry Regiment•Company A - Captain O.T.
