Signed lower right: AR Waud.
Title inscribed below image.
Inscribed above image: fort on Manchester side of the river; guns to repress the prisoners.
Inscribed on verso: [ * ]by a prisoner. As far as topographical accuracy goes it is not to be compared with my sketch It is valuable as giving an idea of the crowd of tents, and the surroundings of the prison. The great guns in battery in the photo are exaggerations[.] in my sketch will be seen a ledge artificially cut in the knoll, upon which two field pices[sic] were mounted to dominate the casup[?] and two others, (as shown) on top of the knoll The embankment was the dead line, the buildings on the right a cook house, The accompanying rough outline will give an idea of how it looked, when tents mostly old "Sibleys" were pitched for the men. in the early days, I am told, the men slept on the ground without shelter or fire.
