This map illustrates the layout of Andersonville Prison, as Sneden refers to the Confederate prison camp, and the surrounding area where Confederate guard troops of the 1st Florida Battery were stationed including the headquarters of Captain Henry Wirz, roads in and out, topographical features such as swampland, a graveyard presumed to be connected with the prison, and "Anderson Village." Sneden revised this map while maintaining his diary (v. 5, p. 560).
