On page 20 of this sketchbook, there is a drawing by Frederick E. Ransom, 11th Illinois Infantry, titled "Soldiers celebrating the Fall of Vicksburg."

Cave Life in Vicksburg: original etching #28 by Adalbert John Volck. Volck was an artist, dentist, and Confederate symaphizer. This illustration is from the set of 29 etchings entitled Confederate War Etchings, published in Philadelpha between 1880 and 1894.

During the Spring and Summer of 1863, the citizens of Vicksburg fled for safety to makeshift "caves" in nearby bluffs. Women, children, older men, and servants sought shelter from the constant bombardment of artillery shells from all directions until July 4, 1863. Beds and tables were squeezed into the cramped burrows, and what scarce food there was turned out to be more plentiful than the fare of the soldiers fighting in the town below.

Mary Loughborough, the young wife of a Confederate officer, kept a diary of her experience, published as My Cave Life in Vicksburg.
