The Edgefield Advertiser published throughout the war, and irtually all the copies have been preserved on microfilm. Some companies of the 14th came from Edgefield District, so you may get lucky there. It is available on microfilm at South Caroliniana, University of Georgia, and Greenville Public Library, among others. Only a few scattered issues of the Greenville Southern Enterprise, and none of the Laurensville Heroad after September, 1861, nor of the Anderson papers.
