1st Battalion, Tennessee Light Artillery (Confederate)
"An attempt was made in May, 1862 to form a regiment of light artillery out of the light artillery batteries which had belonged to the Artillery Corps of Tennessee. The attempt was unsuccessful; no field officers were elected, and the organization was never recognized by the Adjutant and Inspector Generals Office. However, some of the companies were mustered as companies in the First Tennessee Light Artillery Regiment. Some of them later formed a temporary field organization known as the 1st Tennessee Light Artillery Battalion, also called the 1st Tennessee Heavy Artillery Battalion, the remnants of which were permanently consolidated into the 1st Tennessee Heavy Artillery Regiment (q.v.) by order of Major General Leonidas Polk in January, 1864." 
The book "Units of the Confederate States Army" by Joseph H. Crute, Jr. contains no history for this unit. 
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.
