A short-entry manuscript diary of Confederate States soldier Thomas Benton Alexander, written during the Civil War as a member of the 1st Tennessee Heavy Artillery Regiment, Company B (3rd). The diary is a single volume (13 cm) of 59 leaves, with 118 pages of content in Alexander's hand, mostly in pencil. Approximately 70 per cent of this content consists of dated diary entries, ranging from 2 June 1862 to 18 May 1865. Most of these date from March 1863 to the end of the war, and appear in chronological sequence from 11v to 51v. Entries were made with considerable regularity but are generally very brief. The greater part of the diary content (20v to 51v) treats the final sixteen months of the war. Thirty-six pages at the front and back of the volume are devoted mostly to accounts and a considerable variety of other material, some dating to as early as 1861. Among the more significant entries are a list of men killed in the Maury Artillery, December 1861 to July 1863 (2r to 3r); a "song ballad," dated 30 August 1862, "wrote by T. B. Alexander" (57r to 57v); and, most notably, a table (of uncertain origin) indicating the individual Confederate regiments at Fort Donelson, with numbers of troops engaged, killed, and wounded (4v to 7r).
