Alfred Rudolph Waud -- Federal Assault at the Mine, July 30, 1864
Inscribed on separate sheet of cream paper: "Explosion of the mine under the Confederate works at Petersburg July 30th 1864. The spires in the distance mark the location of the city; along the crest, in front of them are the defensive works, it was an angle of these that was blown up, with its guns & defenders. The explosion was the signal for the simultaneous opening of the artillery and musketry of the Union lines. The pickets are seen running in from their pits & shelters on the front, to the outer line of attack. In the middle distance, are the magnificent 8 & 10 inch Mortar batteries, built and commanded by Col. Abbott. Nearer is a line of abandoned rifle pits, and in the foreground is the covered way, a sunken road for communication with the siege works and the conveyance of supplies and ammunition to the forts. The chief Engineer of the A. of P. is standing upon the embankment watching progress throw [sic] a field glass."
Inscribed on an accompanying piece of paper in pencil and black ink: "The advance to the "crater" after the explosion of the mine. In the middle distance are the mounds of earth thrown up by the explosion: beyond upon the high ground cemetery hill the Confederates inner line of works, which if they had carried, would have given the Union Army Petersburg and Richmond.
