The correspondence of George A.C. Barnett consists of a set of 27 letters written to a woman named "Dotty" between the dates of November 30, 1864, and December 25, 1864. The letters were written from Chattanooga, Tennessee. Just as Barnett arrived in Tennessee, the railroad was cut, making it impossible to send or receive mail. As a result, Barnett collected his daily correspondence, numbered each page, and eventually sent the batch of letters as a collected work. The letters, totaling 192 pages, describe Barnett's daily activities, thoughts, and feelings.
A small printed etching of the Three Graces is affixed to the November 30th letter. Pen and ink drawings illustrate the letters of December 18th (a man in tall boots), 19th (a pair of elegant "breeches"), and 20th (a horse).
