48th Regiment, Tennessee Infantry (Nixon's)
The 48th Regiment, Tennessee Infantry (Nixon's)was organized at Corinth, Mississippi, in April, 1862. This unit lost nineteen percent of the 312 engaged at Richmond and fifty percent of the 155 at Chickamauga. On July 31, 1864, Polk's Brigade was broken up and the men from Nixon's 48th Regiment merged into Voorhies' 48th Regiment. 
Companies in this Regiment with the Counties of Origin
Men often enlisted in a company recruited in the counties where they lived though not always. After many battles, companies might be combined because so many men were killed or wounded. However if you are unsure which company your ancestor was in, try the company recruited in his county first.
